National Preparedness Level 3 

Southern California Area

Preparedness Level: (PL 3) 

Northern California Area

Preparedness Level (PL 3) SYNOP:

***Strong north winds across Santa Barbara County and the Grapevine this morning***

***Gusty offshore winds across Southern California early next week***

***Hot and very dry early next week***

Surface high pressure over Northern California will bring north winds of 20 to 30 mph with gusts to 50 mph to much of Santa Barbara County and the Grapevine this morning. High pressure aloft moving in from the south will bring around 10 degrees of warming each day through Monday.  Maximum temperatures will be near normal today, with mid 50s to mid 60s across the mountains and mid 70s to mid 80s in the valleys.  Minimum humidity will be between 15% and 30% today.  Well above normal temperatures will occur Sunday through Tuesday, with record heat Monday and Tuesday.  Minimum humidity will be in the teens Sunday and then in the single digits Monday and Tuesday. Northeast to east winds of 15 to 30 mph with gusts to 50 mph will surface across the mountains and below the canyons and passes of Southern California Monday morning through Tuesday afternoon.  The ridge will weaken bringing a cooling trend and a slight increase in humidity Wednesday through the end of next week.

 NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)

Gusty north winds and low humidity values combined with critical fuel levels will lead Red Flag  conditions this afternoon for the Colorado River Valley zones.  Improving conditions are expected Sunday and into next week as winds decrease, but conditions will remain quite dry.

 

SPECIAL NOTES: N/A

 

DAILY FUELS/FIRE POTENTIAL:

Strong north winds will bring an elevated risk for large fire to much of Santa Barbara County and the Grapevine this morning, but the risk will not be high since humidity will be well above critical levels (mainly between 20% and 40%). Otherwise, there will not be a heightened threat for large fire this weekend as there will just be some local offshore breezes over the wind prone areas.  There will be a high risk for large fire across Southern California from the mountains westward Monday and Tuesday as offshore winds strengthen and become more widespread. Also, when winds reach their peak strength early next week, they will be combined with record heat and single digit humidity. Rapid rates of spread and long range spotting will be likely on any new ignition across Southern California early next week. The large fire threat will decrease significantly Wednesday through the end of next week as winds become light and temperatures cool.  Expect moderate to heavy initial attack activity Monday and Tuesday, otherwise expect light IA activity through the end of next week.

2007: Very strong Santa Ana winds developed on this day and continued through 10/23. A gust of 85 mph was recorded at Fremont Canyon, 79 mph at San Bernardino, 75 mph at Descanso and Mira Loma, and 74 mph at Fallbrook and Rancho Cucamonga. Some locations experienced winds at least 45 mph for more than 36 consecutive hours. Winds caused at least $60 million in damage and destruction to buildings, fences, vehicles, etc. The devastating wildfires of 2007 were fanned by these winds. These fires caused one million Californians to evacuate, the largest mass evacuation in California history. Several notable fires that started on this day include the Witch Creek, Harris, and Santiago Fires. The Witch Creek fire eventually grew into the sixth largest wildfire in California since 1932, consuming 197,990 acres, 1,650 structures, injuring 40, and causing two fatalities. The combined cost of damages and fighting the fire was estimated at more than $1 billion. The Harris and Santiago Fires would scorch 90,440 and 28,445 acres respectively and cost a combined $43 million to fight.

 

2004: A waterspout was spotted two miles southwest of North Island.

 

1965: Newport Beach reached 96°, the all-time highest temperature on record.

 

1957: Widespread thunderstorms developed on 10/20 on this day. Hail drifted to 18 inches deep in East LA. Waterspouts were observed off Point Mugu and Oceanside.

 

1949: It was 34° in Santa Ana, the lowest temperature on record for October. This also occurred on 10/12/1924 and 10/31/1935.=========================================================================TROPICAL EAST PACIFIC REPORT:

National Preparedness Level 3 

Southern California Area

Preparedness Level: (PL 3) 

Northern California Area

Preparedness Level (PL 3) SYNOP:

***Strong north winds across Santa Barbara County and the Grapevine tonight into Saturday morning***

***Gusty offshore winds across Southern California early next week***

***Hot and very dry early next week***

A Pacific trough will bring westerly winds of 20 to 40 mph with gusts to 60 mph across the wind prone mountain and desert areas through this afternoon. This trough will also bring scattered showers away from the deserts with less than a quarter inch of additional rainfall through this afternoon.  Temperatures will be 10 to 20 degrees below normal today, with mid 40s to mid 50s across the mountains and mid 60s to mid 70s in the valleys.  Minimum humidity will be mainly above 30% away from the deserts.   A strong ridge of high pressure will build into California from the southwest bringing significant warming and drying to the region Saturday through early next week.  Temperatures will warm to the 90s across the coastal and valley areas of Southern California on Sunday and be above 100 degrees early next week.  Minimum humidity will be in the teens this weekend and then drop into the single digits early next week.  North winds of 20 to 40 mph with gusts to 60 mph will surface across much of Santa Barbara County and the Grapevine this evening into Saturday morning. There will be northeast to east winds of 15 to 30 mph with gusts to 50 mph across the mountains and below the canyons and passes of Southern California Monday morning through Tuesday afternoon. The strong ridge of high pressure will weaken bringing cooler temperatures and an increase in humidity Wednesday through the end of next week.

 NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)

Strong, southwest winds are expected to develop in a band stretching from San Bernardino to Mohave counties today ahead of an approaching cold front. Cold front will push across the southern Great Basin  today with post-frontal, north winds becoming gusty. Front will exit the area to the south tonight as winds shift to the north and decrease across much of the area late tonight into tomorrow. The exception  will be down the Colorado River Valley where gusty, northerly winds  will continue through the weekend. These winds combined with a drier airmass now in place could create critical fire weather conditions  along the river on Saturday.

 

FRI Morning

Eastern Sierra: West winds gusting as high as 80mph. HIGH WIND WARNING

Owens Valley: Gusts could reach speeds of 50 mph. Most likely near and west of US-395. WIND ADVISORY

 

FRI Morning-FRI Night

San Bernardino Co: Southwest winds gusting 35-45mph, with the strongest winds in the Barstow area as high as 55mph. WIND

ADVISORY

 

Wind will become northerly and decrease FRI night

 

SPECIAL NOTES: n/a

 

DAILY FUELS/FIRE POTENTIAL:

Cool temperatures and high humidity will cause the potential for large fire to remain low today. There will be an elevated threat for large fire across Santa Barbara County and the Grapevine tonight into Saturday morning due to strong north winds.  Rapid rates of spread and long range spotting will be likely if an ignition were to occur in one of these windy areas.  Much of Southern California will see a high risk for large fire Monday and Tuesday as gusty offshore winds combine with single digit humidity and record high temperatures.  Extreme fire behavior will be likely if a new ignition occurs in a windy area early next week.  Any fire that gets beyond its initial attack phase this weekend through early next week will burn actively at night due to poor humidity recovery.  Expect light initial attack activity through Sunday and then moderate to heavy IA activity early next week.

=================================

THIS DAY IN WEATHER HISTORY:

2004: A large winter season storm pummeled Southern California. Not just daily, but monthly record rainfall was received in only one day across the region. The same happened again on 10/27. The monthly record rainfall was exceeded in only six hours in many locations of Orange County on this day. Totals for last two weeks of October were four to eight inches in lower elevations, and up to 14 inches at Lake Arrowhead. On this day a storm wind of 39 mph was measured at Lindbergh Field from the south, the strongest October wind on record. Seven daily rainfall records fell on this day: Palomar Mountain (6.20), Big Bear Lake (3.25 inch), Santa Ana (3.15), Idyllwild (2.65), Campo (2.64), Riverside (2.50), and Vista (1.88). 3.5 inches of snow fell in Idyllwild, the greatest daily amount on record for October. Widespread flooding occurred. A bridge washed out near Wrightwood. One motorist was killed in floodwaters near Lytle Creek. Many mountain roads were impassable with mud and rockslides. Railroad tracks in Fontana washed out, derailing a train. The Santa Ana River flooded, putting horses neck-deep in flood waters in Norco and a rescue was made at a Chino golf course. Several funnel clouds were reported offshore from San Clemente.

1965: A very long heat wave began on this day and ended on 10/29. A peak temperature of 104° was reached at San Diego on 10/22 and 100° in Los Angeles. LA had ten consecutive days with afternoon highs reaching at least 90°.

1957: Widespread thunderstorms developed each day on this day and on 10/21. Hail drifted to 18 inches deep in East LA. Waterspouts were sighted off Point Mugu and Oceanside.

Preparedness Level: (PL 3) 

Northern California Area

Preparedness Level (PL 4) SYNOP:

***Cooler and windy across the mountains and deserts today and Friday***

***Hot, dry and breezy over the weekend into early next week***

A strong storm system over the Pacific Northwest will usher in a short period of cooler and more humid weather the next two days. Temperatures will continue to decline the next two days, and by Friday, highs will be in the 50s in the mountains, 60s at the coast to the upper 70s in the valleys.  Some light showers will be possible across the central coast and the Sierras from Yosemite N.P. northward tonight into Friday.  All precipitation amounts are expected to be under 0.25 of an inch.  Further south, a deep marine layer may bring some drizzle to areas near the mountains Friday morning.  It will be windy in the deserts and Sierras this afternoon through Friday evening.  In general, winds will be in the 25-40 mph in the deserts and the Sierras above 8,000 feet through Friday evening.  Strong gusts will be possible tonight along the Crest.  After the front passes eastward, north winds of 20-30 mph will be possible in Santa Barbara County and the I-5 Corridor Friday night into Saturday.  Similar wind speeds can be expected through the Cajon Pass Saturday.  The winds will transition to an offshore orientation Saturday night into Sunday morning.  At this time, the strongest offshore winds are anticipated to occur Sunday night and Monday night when some gusts to 35 mph will be possible over Southern California.  The offshore winds do not appear to be overly strong, but they will last for several days and may cover a wide area as opposed to the last two events which were more focused on discrete areas. The primary concern during the outlook period will be the return of very hot and dry weather as the offshore flow couples with a strong ridge of high pressure across the state.  High temperatures next Sunday through Tuesday will be in the 90s in the interior valleys and foothills of Central California to 100-105 across the valleys and even the coastal areas of Southern California. Minimum RH will be in the single digits below 6,000 feet with poor recovery at night.  Cooler weather may slowly return next Wednesday or Thursday.

 NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)

  • HIGH WIND WARNING has been issued for the eastern Sierra and a WIND ADVISORY for the Owens Valley from midnight tonight through 8 AM Friday.
  • A second WIND ADVISORY has been issued for northwest San Bernardino County  8 AM  Friday- 8 PM Friday.

Clouds will decrease from west to east today as isolated showers gradually move out of Lincoln and Mohave counties into Utah. Winds will begin to increase this afternoon, with strong downslope winds expected on the eastern slopes of the Sierra tonight and Friday morning and strong west winds expected in northwest San  Bernardino County Friday. A cold front will pass through the southern Great Basin Friday and the Mojave Desert Friday evening, bringing gusty north winds to the Colorado River Valley Saturday.  High pressure will bring quiet weather Sunday through the first half of next week, except for periods of gusty north winds in the Colorado River Valley.

 

Cold Front will Move through Friday Afternoon and Friday Night

 

Tonight-Friday Morning

Strong west winds, with gusts as high as 70-80 mph, will be possible along the eastern slopes of the Sierra. Gusts that make it into

the Owens Valley could reach speeds of 40-50 mph.

 

Friday-Friday night

Increasing winds across the Western Mojave Desert will reach sustained speeds of 25-35 mph gusting 45-55 mph.

Wind will become northerly and decrease Friday night.

 

 

SPECIAL NOTES:

Changes Since Last Briefing:

High confidence in a significant heat wave with Santa Ana winds Sunday (10/22) through at least Monday (10/23), likely leading to critical fire weather conditions and heat impacts in the valleys and coast.

 

Weather Summary

Santa Ana winds (weak to moderate strength) and very strong high pressure aloft will create hot, dry and windy conditions Sunday through Monday, and likely into Tuesday (10/24) as well for many areas.

 

Weather Threats, Impacts, Locations and Timing:

  • There’s a chance that fire weather conditions could be critical near the Cajon Pass late Saturday (10/21). Then, critical fire weather conditions likely through/below the canyons and passes (including Cajon Pass and San Gorgonio Pass) and into the coastal foothills and coastal slopes of San Bernardino, Riverside, Orange and San Diego counties Sunday through Monday and perhaps Tuesday as well.
  • Hot weather Sunday through Tuesday all the way to the coast, possibly reaching Heat Advisory levels.

 

Forecast Winds:

  • Northeast to East 15-25 mph with gusts 30-40 mph and local 50 mph.

 

Forecast Relative Humidity:

  • Day-time humidity of 5-10% away from the coast with very poor overnight recoveries.

Forecast High Temperatures and Heat Risks:

  • Monday (10/23):
    • Beaches: 88-93
    • Few miles inland from the Coast and into the Valleys: 97-105
    • Lower Mountain Elevations: 80s
    • Higher Mountain Elevations: 70s
    • High Deserts: 80s
    • Lower Deserts: 97-102

 

DAILY FUELS/FIRE POTENTIAL:

Large fire potential will continue to be low through Friday due to cooler and more humid weather. There will be some pockets of locally low RH this afternoon and evening due to downsloping winds on the east side of the Kern County Mountains and east of the Sierra Crest, but RH should climb quickly this evening into the overnight hours. A return of sunny, hot and dry weather will result in another round of elevated large fire potential across much of the district Sunday through the first half of next week.  Temperatures will likely surpass record readings over Southern California and the kiln-like dryness will cause fuel moisture levels to reach record low readings over most of Southern California.  Gusty winds during the night through morning hours will add to the fire threat.  The highest likelihood of large fires may be over the entire coastal strip and adjacent valleys from Ventura to San Diego County due to very hot temperatures, local winds and persistently low RH. This includes many urban interface regions. Expect very aggressive fire behavior during peak heating hours with active burning at night in the windy areas.  High levels of initial attack and resource demand are anticipated beginning Sunday.

heat wave and santa ana update

Changes Since Last Briefing:

High confidence in a significant heat wave with Santa Ana winds Sunday (10/22) through at least Monday (10/23), likely leading to critical fire weather conditions and heat impacts in the valleys and coast.

 

Weather Summary

Santa Ana winds (weak to moderate strength) and very strong high pressure aloft will create hot, dry and windy conditions Sunday through Monday, and likely into Tuesday (10/24) as well for many areas.

 

Weather Threats, Impacts, Locations and Timing:

  • There’s a chance that fire weather conditions could be critical near the Cajon Pass late Saturday (10/21). Then, critical fire weather conditions likely through/below the canyons and passes (including Cajon Pass and San Gorgonio Pass) and into the coastal foothills and coastal slopes of San Bernardino, Riverside, Orange and San Diego counties Sunday through Monday and perhaps Tuesday as well.
  • Hot weather Sunday through Tuesday all the way to the coast, possibly reaching Heat Advisory levels.

 

Forecast Winds:

  • Northeast to East 15-25 mph with gusts 30-40 mph and local 50 mph.

 

Forecast Relative Humidity:

  • Day-time humidity of 5-10% away from the coast with very poor overnight recoveries.

Forecast High Temperatures and Heat Risks:

  • Monday (10/23):
    • Beaches: 88-93
    • Few miles inland from the Coast and into the Valleys: 97-105
    • Lower Mountain Elevations: 80s

National Preparedness Level 3 

Southern California Area

Preparedness Level: (PL 3) 

Northern California Area

Preparedness Level (PL 4) SYNOP:

***Cooling trend through Friday ***

***Hot, dry and breezy over the weekend into early next week***

Cooler weather is expected over the next few days as a sizable trough moves into the Pacific Northwest. Onshore flow coupled with southwesterly flow aloft should allow temperatures to fall 5-8 degrees today with highs reaching the lower 70s at the coast to the lower 90s in the valleys of Southern California. RH will generally be higher this afternoon, but some single digit RH will be possible in desert-adjacent areas of the mountains. The main front associated with the trough will move inland Thursday, bringing a good chance of wetting rain for much of the northern part of the state. The trough will reach the district Thursday night into Friday. Most of the moisture will remain to our north, but light wetting rains will be possible across the Monterey Peninsula and in the Sierras from Yosemite N.P. northward. West winds of 20-30 mph with gusts to 40 mph will develop Thursday afternoon and again Friday in and near the Antelope Valley and the Banning Pass. Highs will drop to near normal readings by Friday with widespread marine layer stratus returning to the coast during the night and morning hours. The cool weather will be short-lived as a strong warming trend will begin over the weekend which will continue into the first half of next week.

A strong ridge along with weak offshore flow will generate record high temperatures across much of Southern California Sunday through next Tuesday.   This ridge looks to be exceptionally amplified for this time of year and the entire district should see temperatures 10-20 degrees above normal. Highs will reach the lower 90s across the valleys and lower foothills of Central California with readings over 100 over Southern California west of the mountains. Very hot weather will extend all the way to the coast as no marine layer will be present to mollify temperatures by Sunday. At this time, the offshore winds do not appear to be strong, but northeast winds of 15-25 mph will be possible Sunday and again next Tuesday. Minimum RH will fall into the single digits with poor recovery over most areas. Cooler weather may slowly return next Thursday.

 NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)

A weak disturbance will bring a slight chance of light showers to the higher elevations in southeast California this  morning, and southern Nevada and northwest Arizona this afternoon  and evening. Otherwise, dry weather is expected through Thursday  with temperatures a few degrees above normal. A storm system will bring a risk of downslope winds on the east slopes of the Sierra  Thursday night and strong west winds across the Mojave Desert on  Friday, along with cooler temperatures for Friday and Saturday.  Quiet weather is expected to return for Sunday and much of next  week.

 

Cold Front will Move through Friday Afternoon and Friday Night

Downslope winds along the eastern slopes of the Sierra and Spring Mountains will be possible as early as late Thursday night continuing through early Friday morning. Lower elevation speeds: 20-25 mph gusting 30-40 mph.

 

Elsewhere, west winds increase Friday afternoon.

Best chance for strong winds will be through Clark , San Bernardino, and northern Mohave Counties. Sustained wind 20-30 mph,

gusts up to 45 mph.

 

Potential for stronger winds exists.

Wind will become northerly and de crease Friday night

 

SPECIAL NOTES:

 

DAILY FUELS/FIRE POTENTIAL:

Fire activity and ignition potential should lower through Friday due to cooler weather and much higher RH. But by Sunday, a return of hot, dry and sunny weather will cause large fire potential to be elevated once again. The heat and low RH will be the primary threats over the weekend into early next week as temperatures look to be as hot, or perhaps even hotter, and more widespread than during the heatwave earlier this week. Central California will see temperatures 5-10 degrees warmer than last week which may allow fire activity to occur over nearly the entire district instead of the threat being confined to just Southern California. But the threat will likely be highest over areas such as Ventura, northern Los Angeles and Orange County where some light offshore winds will be possible. Dead fuel moisture is at record low readings currently, and conditions will only become drier over the weekend into early next week. Light IA is expected through Saturday, then heavy IA and resource demand is possible Sunday through early next week.

National Preparedness Level 3 

Southern California Area

Preparedness Level: (PL 3) 

Northern California Area

Preparedness Level (PL 4) SYNOP:

***Hot temperatures, low RH today***

***Isolated high-based showers and 1 or 2 thunderstorms possible portions of central coast this afternoon***

***Hot, dry and breezy again this coming weekend***

Today will be hot and dry once again today with temperatures close to 100 in the valleys and lower foothills of Southern California. Minimum RH will be in the single digits over a wide area of the district with the lowest readings likely over interior sections of Southern California.  A weak disturbance offshore will generate some convection off the central coast this morning.  It is expected to fall apart as it moves east, but some clouds and virga may occur, mainly in San Luis Obispo County, this afternoon. One or two lightning discharges may occur in this area this afternoon. A trough over the Pacific Northwest will bring cooler weather to the region beginning Wednesday.  Very light wetting rains may occur over Monterey County and Yosemite National Park Thursday night and Friday.  Temperatures will be close to normal by Friday with highs in the lower 70s at the coast to the lower 80s in the valleys.  Expect RH to recover at lower elevations during the second half of the week, but inland areas and places above 5,000 feet may continue to see minimum readings in the teens.   Another offshore event looks likely beginning Saturday night which may last through next Tuesday. Expect temperatures close to 100 over Southern California with RH in the single digits next Sunday and Monday. At this time, the wind speeds do not appear to be overly strong, but it will certainly be as hot and dry as last weekend.  No precipitation is expected through the period.

 NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)

A weak disturbance will bring a slight chance of light  showers to the higher elevations from Las Vegas northward tonight  and Wednesday, otherwise dry weather is expected through Thursday  with temperatures a few degrees above normal. A storm system will  bring a risk of downslope winds on the east slopes of the Sierra  Thursday night and strong west winds across the Mojave Desert on  Friday, along with cooler temperatures for Friday and Saturday.

 

Cold Front will Move through Friday Afternoon and Friday Night

Downslope winds along the eastern slopes of the Sierra and Spring Mountains will be possible as early as late Thursday night

continuing through early Friday morning. Lower elevation speeds: 20-25 mph gusting 30-40 mph.

Elsewhere, west winds increase Friday afternoon.

Best chance for strong winds will be through Clark , San Bernardino, and northern Mohave Counties. Sustained wind 20-30 mph,

gusts up to 45 mph.

Potential for stronger winds exists.

Wind will become northerly and de crease Friday night.

 

SPECIAL NOTES:

BI-MONTHLY FUELS DISCUSSION

For Southern and Central California

 

Updated: Thursday, October 12th, 2017

Next Routine Update: Thursday, October 26th, 2017

 

General Discussion:

 

September ended much like it began; hot and dry. An offshore flow along with high pressure along the coast

resulted in well above normal temperatures with very low daytime RH. The heatwave ended after the first few

days of October, but a strong offshore wind event occurred on the 8-9th which resulted in a drastic upswing in

fire activity across the state. North winds brought a drying wind to Central and Northern California and large

fires erupted in Napa and Sonoma Counties. In Southern California, a new start just west of last month’s

Canyon fire grew rapidly in the space of a few hours consuming 24 residences and thousands of acres. The

flames were fanned by strong Santa Ana winds with gusts over 60 mph during the afternoon of the 9th.

The rapid growth of fire activity underscores the dangerous fuel conditions across the area. NFDRS

calculations show dead fuel moisture is near or even surpassing record dryness levels across much of

Southern California. During the fires, all fuel types burned actively, and at times, explosively. The combination

of extremely dry fuels, a heavy growth from last year’s rain and a high dead fuel component will allow for very

rapid rates of spread and aggressive fire behavior during hot or windy periods. Only a heavy rainfall will lower

the potential for large fires much in the long term. For most, a chance of significant wetting rains is several

weeks away.

 

DAILY FUELS/FIRE POTENTIAL:

Large fire potential will continue to be elevated across the entire district due to hot temperatures, low RH and extremely dry fuels. There is an extremely remote chance of lightning generating a new start along the central coast this afternoon, but the highest likelihood of new fires will continue to be over Southern California due to near record high temperatures.  After a few cooler days, large fire potential will be elevated once again Sunday through the first half of next week due to the return of hot, dry weather. Dead fuel moisture is at record low readings over Southern California, and in general, near record low readings over the central part of the state.  The hot, sunny and dry weather will produce exceedingly high burning indices next week on south slopes and aggressive fire spread can be expected during peak heating hours.  Poor RH recovery will lead to active burning at night.  IA may be moderate today, then moderate to heavy again Sunday through the first half of next week.  Some precipitation over the northern part of the state may aid deployed resources across ongoing large incidents later this week.

2015: A brief landspout touched down in Menifee with no serious damage.

 

2005: A supercell thunderstorm produced penny size hail in Yorba Linda. Meanwhile, another storm dropped 1.70 inches of rain on Thermal, setting a daily record for the month of October.

 

2004: A tornado hit Oceanside. It was a waterspout that came ashore. Damage was done to structures, trees, windows, and an elementary school. Another funnel cloud occurred off Encinitas’ Moonlight Beach. This was the first day with measurable rain in San Diego since 4/17. A streak of 182 consecutive days of no measurable rain, the longest on record, ended on 10/16. Incredibly, this rain was the start of the wettest October on record.

 

1948: 1.89 inches of rain fell in Borrego Springs, the greatest daily amount on record for October.

 

1936: 3.77 inches of rain fell in Escondido, the greatest daily amount on record for October.=========================================================================TROPICAL EAST PACIFIC REPORT:

For the eastern North Pacific…east of 140 degrees west longitude:

 

Showers and thunderstorms associated with a low pressure area

located about a thousand miles west of the southern tip of the Baja

California peninsula have become significantly less organized since

this morning due to very strong upper-level winds. In addition,

the low has moved over colder waters, and development of this system

is becoming less likely while it moves northwestward at about 10

mph.

* Formation chance through 48 hours…low…30 percent.

* Formation chance through 5 days…low…30 percent.

 

Another low pressure area located about 1300 miles east-southeast

of the Hawaiian Islands is producing disorganized showers and a few

thunderstorms while moving west-northwestward at about 10 mph.

Development of this system is not expected due to increasing

upper-level winds and proximity of dry air.

* Formation chance through 48 hours…low…near 0 percent.

* Formation chance through 5 days…low…near 0 percent.

National Preparedness Level 3 

Southern California Area

Preparedness Level: (PL 3) 

Northern California Area

Preparedness Level (PL 4) SYNOP:

***Hot and very dry today***

***Strong north winds across Santa Barbara County and the Grapevine Friday night through Saturday morning***

***Strong offshore winds along with hot and very dry conditions across Southern California Sunday morning through Tuesday morning***

Strong high pressure aloft over California will bring hot and very dry conditions to the entire region today. Temperatures will be 10 to 20 degrees above normal, with 70s to low 80s across the mountains, mid 80s to low 90s in the Central California valleys, and mid 90s to 102 in the Southern California valleys. There will be widespread single digit humidity across the area today. High pressure will weaken Tuesday and Wednesday and then a Pacific trough will approach the West Coast Thursday and push inland Friday bringing a cooling trend and an increase in humidity. Temperatures will be near normal Thursday and 5 to 10 degrees below normal Friday. Westerly winds of 20 to 30 mph with gusts to 50 mph will surface across the wind prone mountain and desert areas Thursday afternoon through Friday afternoon.

A strong ridge of high pressure will build into California from the southwest bringing significant warming along with minimum humidity in the single digits and teens Saturday through early next week. Widespread 90s will occur across the coastal and valley locations of Southern California starting Sunday. Northerly winds of 20 to 30 mph with gusts to 50 mph will surface across much of Santa Barbara County and the Grapevine Friday night through Saturday morning and then these strong and gusty winds will transition to the northeast and east Sunday morning through Tuesday morning and affect much of Southern California.

 NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)

Dry conditions are expected areawide through Thursday,  with temperatures rising a few degrees above normal. A Pacific  trough will bring increasing clouds and winds, cooler temperatures,  and chances for precipitation to parts of the area Thursday night  through Friday night before high pressure returns for the weekend

 

SPECIAL NOTES:

Weather Summary

It will stay very dry (day-time humidity 5-10% away from the coast) and very warm/hot tomorrow and Tuesday, but offshore winds will be mostly light.

 

Looking ahead towards the next period of potentially critical fire weather conditions… a very dry, hot and windy (Santa Ana winds) weather pattern is possible next weekend in extreme southwest California, particularly Sunday (10/22) and Monday (10/23). The heat could reach excessive levels as well. Stay tuned!

 

DAILY FUELS/FIRE POTENTIAL:

Even though temperatures will be well above normal and humidity will be very low the next couple of days, the potential for large fire will be low due to light winds. The large fire threat will continue to be low across the region late this week due to cool temperatures and high humidity. Initial attack activity will be light across the region through the end of this week.

The potential for large fire will increase this weekend through early next week as strong offshore winds combine with hot temperatures and single digit humidity. This Santa Ana event looks to be the strongest and longest in duration of the season and “High Risk” days will be likely across much of Southern California Sunday through early next week. Moderate to heavy initial attack activity will be possible Sunday through early next week.

For the eastern North Pacific…east of 140 degrees west longitude:

 

Shower and thunderstorm activity associated with a broad low

pressure area located about 750 miles west-southwest of the

southern tip of the Baja California peninsula has become less

organized this afternoon. This system is forecast to move

west-northwestward or northwestward into less conducive

environmental conditions on Monday, and the chance of this system

becoming a tropical cyclone appears to be decreasing.

* Formation chance through 48 hours…medium…60 percent.

* Formation chance through 5 days…medium…60 percent.

 

Another low pressure area located about 1600 miles east-southeast

of the Hawaiian Islands is producing disorganized showers and

thunderstorms. Strong upper-level winds are expected to inhibit

significant development of this system while it moves westward at

10 to 15 mph during the next couple of days.

* Formation chance through 48 hours…low…10 percent.

* Formation chance through 5 days…low…10 percent.

National Preparedness Level 3 

Southern California Area

Preparedness Level: (PL 3) 

Northern California Area

Preparedness Level (PL 4) SYNOP:

***Gusty offshore winds across Southern California this morning***

***Very warm and dry through Wednesday***

Northeast to east winds of 15 to 25 mph with gusts to 40 mph will continue to surface across the mountains and below the canyons and passes of Southern California this morning as surface high pressure remains over the Great Basin. Temperatures will continue to warm through Monday as high pressure aloft strengthens over California.  Maximum temperatures will be in the mid 60s to mid 70s across the mountains, 80s in the Central California valleys, and 90s in the Southern California valleys today, with 70s to low 80s across the mountains, mid 80s to low 90s in the Central California valleys, and mid 90s to 102 in the Southern California valleys Monday.

Temperatures will only cool a couple degrees away from the coast Tuesday and Wednesday as high pressure aloft only weakens a little. Minimum humidity will be mainly in the single digits and teens away from the coast through Wednesday.  Winds will be light across the entire area this evening through the middle of this week.  A Pacific trough will approach the West Coast Thursday and move inland Friday bringing significant cooling and a large increase in humidity to the region.  Scattered showers with light rainfall totals will be possible Friday.  Westerly winds of 15 to 25 mph with gusts to 40 mph will occur over the wind prone mountain and desert areas Thursday and then increase to 20 to 30 mph with gusts to 50 mph Friday.

   NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)

Windy conditions will continue in the Colorado River Valley until early this afternoon. Mostly clear and dry conditions are expected area wide through the first half of the week, with temperatures warming each day. A Pacific trough will bring  increasing clouds and winds, cooler temperatures, and chances for  precipitation to parts of the area later in the week.

 

SPECIAL NOTES:

BI-MONTHLY FUELS DISCUSSION

For Southern and Central California’

 

General Discussion:

September ended much like it began; hot and dry. An offshore flow along with high pressure along the coast

resulted in well above normal temperatures with very low daytime RH. The heatwave ended after the first few

days of October, but a strong offshore wind event occurred on the 8-9th which resulted in a drastic upswing in

fire activity across the state. North winds brought a drying wind to Central and Northern California and large

fires erupted in Napa and Sonoma Counties. In Southern California, a new start just west of last month’s

Canyon fire grew rapidly in the space of a few hours consuming 24 residences and thousands of acres. The

flames were fanned by strong Santa Ana winds with gusts over 60 mph during the afternoon of the 9th.

The rapid growth of fire activity underscores the dangerous fuel conditions across the area. NFDRS

calculations show dead fuel moisture is near or even surpassing record dryness levels across much of

Southern California. During the fires, all fuel types burned actively, and at times, explosively. The combination

of extremely dry fuels, a heavy growth from last year’s rain and a high dead fuel component will allow for very

rapid rates of spread and aggressive fire behavior during hot or windy periods. Only a heavy rainfall will lower

the potential for large fires much in the long term. For most, a chance of significant wetting rains is several

weeks away.

 

DAILY FUELS/FIRE POTENTIAL:

Gusty offshore winds along with single digit humidity will keep the potential for large fire elevated across Southern California from the mountains westward this morning. Winds are not strong enough or widespread enough for a “High Risk” day.  However, a large fire will still be likely if an ignition were to occur in a windy area.  Even though it will continue to be very warm and dry Monday through Wednesday, the large fire threat will decrease significantly due to light winds.  Without wind, any new fire will likely remain small.  Cool and humid conditions will cause the large fire threat to become low late this week.  Expect moderate initial attack activity today and then light IA activity Monday through the end of this week.

2015: Strong thunderstorms generated gusty and damaging winds estimated at least 60 mph along the western side of the Salton Sea. Winds blew down over 10 power poles several miles to the northwest of the town of Salton City. Unseasonable high pressure and warm ocean waters led to very warm October days and the warmest October nights on record from 10/10 through this day. In San Diego, five out of the six highest October minimum temperatures on record occurred. The highest minimum temperature in any October was 76° on 10/10 and again on 10/13. This is only two degrees off the highest minimum temperature for any time of year! (Only seven nights in history recorded 77 or 78°, all of which occurred during September, meaning these October nights were warmer than any night in July or August in San Diego). On 10/10 the highest minimum temperature in October was also recorded in Chula Vista (73, only three degrees off all-time highest), Oceanside Harbor (74, only two degrees off all-time highest), and El Cajon (tied 69). On 10/13 Santa Ana recorded 78°, the highest October minimum temperature on record. The top six warmest October nights on the Chula Vista record occurred this month, and the top five in El Cajon occurred this month.

 

1965: One man died when an offshore gale capsized his fishing boat off the coast.

 

1961: Hot Santa Ana winds drove temperatures skyward at the coast for a second consecutive day, reaching 104° in Santa Ana, 102° in San Bernardino, Riverside, and La Mesa, 100° in Laguna Beach, 97° in San Diego, and 93° in Newport Beach.=========================================================================TROPICAL EAST PACIFIC REPORT:

For the eastern North Pacific…east of 140 degrees west longitude:

 

The low pressure system located several hundred miles southwest of

the southern tip of the Baja California peninsula continues to

become better defined. Environmental conditions appear conducive

for additional development and a tropical depression is likely to

form during the next day or two while the low moves toward the

west-northwest or northwest at 10 to 15 mph.

 

* Formation chance through 48 hours…high…80 percent.

 

* Formation chance through 5 days…high…80 percent.

National Preparedness Level 3 

Southern California Area

Preparedness Level: (PL 3) 

Northern California Area

Preparedness Level (PL 4) SYNOP:

***Strong offshore winds across Southern California through Sunday morning***

***Very warm and dry through Monday***

Strong surface high pressure over the Great Basin will bring northeast winds of 15 to 30 mph with gusts to 50 mph to the mountains and below the canyons and passes of Southern California through Sunday morning. Widespread minimum humidity in the single digits and teens will occur through Monday and there will be poor humidity recovery tonight and Sunday night.  High pressure aloft building into California from the south will bring a warming trend through Monday.  Maximum temperatures will be in the 60s to low 70s across the mountains and 80s to low 90s in the valleys today.  Some valley locations across Southern California will hit 100 degrees on Monday.  The ridge of high pressure over California will weaken bringing cooler temperatures and higher humidity to the region Tuesday and Wednesday.  Westerly winds of 15 to 25 mph with gusts to 40 mph will surface across the mountain ridges and desert passes Tuesday and Wednesday.  A Pacific trough will bring below normal temperatures and possible showers to the area late next week.  This trough will also bring westerly winds of 20 to 30 mph with gusts to 50 mph to the mountains and deserts late next week.

 NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)

The Red Flag Warning remains in effect for CA zone  229…NV zone 466…and AZ zone 101 from late this morning through  early afternoon Sunday. A passing cold front will lead to strong  north winds of 25 to 35 MPH with gusts to 45 MPH down the Colorado  River Valley. This along with critical RH values and sufficiently  dry fuels may lead to extreme fire behavior. For the remaining  zones, winds will be breezy on Saturday but should generally stay  below 25 MPH; after Saturday, winds will become fairly light through  at least Tuesday. Mostly clear skies and dry weather are expected  through early next week

 

SPECIAL NOTES:

Changes Since Last Briefing:

Fire Weather Watch elevated to Red Flag Warning from late Saturday morning through midday Sunday.  Otherwise, no changes since the Thursday briefing.

 

Weather Summary

 

High pressure will build over the Great Basin Saturday and combine with mountain waves from the San Bernardino Mountains and bring strong gusty winds late morning Saturday through midday Sunday. This will be accompanied by very low humidity and dry fuels.  Winds will decrease by Sunday afternoon, but humidity will continue to be low through Monday.

 

Weather Threats and Impacts:

 

Strong winds and low humidity will cause critical fire weather conditions, mainly in the San Bernardino County Mountains, Inland Empire, Santa Ana Mountains and inland Orange County.

 

Forecast Winds:

 

  • Areas of northeast winds 20 to 30 MPH with local gusts to 50 MPH.  Strongest winds will be through and below passes and canyons.
  • Confidence: Moderately high.

 

Forecast Relative Humidity:

 

Minimums both Saturday and Sunday will be 5 to 10 percent over most areas more than 15 miles from the coast.

 

Confidence: High

 

Timing:

 

WInds will increase late Saturday morning and continue at times through late morning Sunday.  Winds will decrease midday and afternoon Sunday.  Relative humidity will be low late-morning Saturday through Monday.

 

Confidence: High

 

Locations Impacted:

 

    • San Bernardino County Mountains (especially southwest slopes and near Cajon Pass)
    • Inland Empire
    • Santa Ana Mountains
    • Inland Orange County (mainly near the Santa Ana Mountains)

 

DAILY FUELS/FIRE POTENTIAL:

The potential for large fire will be high across most of Southern California from the mountains westward through Sunday due to strong and gusty offshore winds along with single digit humidity and very warm temperatures.  Extreme fire behavior will be likely on any new ignitions across Southern California, since the fuels are extremely dry and very receptive to fire.  Santa Ana winds will fan any new ignition causing rapid fire growth and long range spotting.  Moderate to heavy initial attack activity will most likely occur through this weekend.  The large fire threat will decrease significantly on Monday as winds become light and then the potential for large fire will become low Tuesday through the end of next week as temperatures cool and humidity increases.  Initial attack activity will become light Monday through the end of next week

2015: Unseasonable high pressure and warm ocean waters led to very warm October days and the warmest October nights on record from 10/10 through 10/15. In San Diego, five out of the six highest October minimum temperatures on record occurred. The highest minimum temperature in any October was 76° on 10/10 and again on 10/13. This is only two degrees off the highest minimum temperature for any time of year! (Only seven nights in history recorded 77 or 78°, all of which occurred during September, meaning these October nights were warmer than any night in July or August in San Diego). On 10/10 the highest minimum temperature in October was also recorded in Chula Vista (73, only three degrees off all-time highest), Oceanside Harbor (74, only two degrees off all-time highest), and El Cajon (tied 69). On 10/13 Santa Ana recorded 78°, the highest October minimum temperature on record. The top six warmest October nights on the Chula Vista record occurred this month, and the top five in El Cajon occurred this month.

 

1997: Santa Ana wind gusts measured 87 mph in central Orange County and contributed to a large fire.

 

1971: It was 97° at Palomar Mountain, the highest temperature on record for October.

 

1961: Hot Santa Ana winds drove the temperature to 110° in Long Beach, the hottest in the nation, 107° in San Diego (the highest on record for October), 105° in LA, and over 100° in many coastal and inland locations. It was 88° at San Nicolas Island.

 

1957: An early season storm brought daily record rainfall to Southern California. Over an inch fell at many mountain locations and in parts of central San Diego County. La Mesa recorded 1.08 inch.=========================================================================TROPICAL EAST PACIFIC REPORT:

For the eastern North Pacific…east of 140 degrees west longitude:

 

Showers and thunderstorms are showing signs of organization in

association with a low pressure area centered about 800 miles south

of the southern tip of the Baja California peninsula. Some

additional development of this system is likely, and a tropical

depression could form over the next day or two while it moves toward

the west-northwest at 10 to 15 mph. By late Monday, upper-level

winds look less favorable for development.

* Formation chance through 48 hours…medium…50 percent.

* Formation chance through 5 days…medium…60 percent.
