FIRE WEATHER WATCH FOR MUCH OF EXTREME SOUTHWESTERN CALIFORNIA FOR LATE TONIGHT THROUGH FRIDAY EVENING FOR STRONG GUSTY WINDS AND LOW HUMIDITY…

Onshore flow will strengthen into Wednesday evening spreading cooling and higher coastal humidity inland with gusty southwest to west winds in the mountains and deserts. Periods of strong and gusty Santa Ana winds will develop late Wednesday night in the San Bernardino County mountains and valleys, then spread southward into San Diego County mountains and valleys Thursday
morning with the winds becoming more widespread Thursday afternoon. Periods of strong and gusty winds will continue into Friday. Lowest daytime humidity will fall to 5 to 10 percent Thursday and around 5 percent Friday with poor overnight recovery. This will cause critical fire weather conditions for Thursday
into Friday for much of extreme southwestern California. Very low humidity will continue into Saturday, but with weaker and more localized winds. There will be a slow recovery in humidity for Sunday and Monday. Temperatures will cool into Wednesday for coastal and valley areas and into Thursday for the mountains and
deserts followed by a warming trend into Sunday and Monday.

Cooling trend through Wednesday with highs dropping 5-8 degrees each day. By Wednesday, highs will be in the 60s in the mountains to the upper 70s to low 80s in the valleys. Temperatures will warm up a few degrees Saturday and Sunday

· West winds 20-30 mph with gusts to 50 mph Wednesday in the Kern County Mountains, Antelope Valley and Banning Pass eastward into the desert.

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
RED FLAG WARNING IN EFFECT FROM 2 PM WEDNESDAY TO 5 PM PDT
THURSDAY FOR ALL OF SOUTHERN NEVADA FOR STRONG POST FRONTAL NORTH
WINDS…

…RED FLAG WARNING IN EFFECT FROM 2 PM PDT /2 PM MST/ WEDNESDAY
TO 11 AM PDT /11 AM MST/ FRIDAY FOR THE LOWER COLORADO RIVER
VALLEY FOR STRONG POST FRONTAL NORTH WINDS…

.Strong north winds and low relative humidity will develop over southern Nevada and surrounding states Wednesday afternoon through Thursday behind a fast moving dry cold front. This will lead to critical fire weather conditions for parts of the region though high temperatures will fall about 20 degrees between Wednesday and Thursday. The strongest winds can be expected along the Colorado River Valley…especially between Lake Mohave and Lake Havasu where gusts of 45 to 55 mph are possible. Minimum RH`s will remain below 15 percent across the region with little night time relief. As a result, a Red Flag Warning has
been issued for all of the southern NV zones including zones 460, 461, 462, 463, 464, and 465, as well as the Lower Colorado River Valley which include AZ 101, NV 466, and CA 229. The Red Flag Warning will be in effect 2PM Wednesday through 5PM Thursday for southern NV zones. Wind are expected to remain elevated down the Colorado River Valley through Friday morning where the Red Flag Warning will be in effect through 11AM Friday.

CHANGES SINCE PREVIOUS BRIEFING
Issued a Wind Advisory for all of southern NV, portions of southeast CA, and the Lower Colorado River Valley.
Issued a Red Flag Warning for all of southern NV and the Lower Colorado River Valley.

CONFIDENCE AND DETAILS
Southern Nevada/Northwest Arizona/Southeast California
HIGH Confidence
Dangerous boating conditions due to strong winds and significant wave activity from Lake Mead to Lake Havasu.
Extreme fire behavior and rapid fire growth for parts of southern NV/northwest AZ especially along the Colorado River Valley.
Hazardous crosswinds on east-west oriented roads, especially for high profile vehicles.

Details:

WINDS
Wind Advisory in effect from 2PM WED – 5PM THU for southern NV & portions of southeast CA and for the Colorado River Valley & portions of eastern San Bernardino
County from 2PM WED – 11AM FRI.
Gusty north winds of 35 to 45 mph will spread across the region Wednesday afternoon through Thursday. Strongest winds will be down the Colorado River Valley and far
eastern San Bernardino County where wind gusts to 50-55 mph will be possible WED night through Friday morning.

FIRE WEATHER
Red Flag Warning will be in effect for southern NV from 2PM WED-5PM FRI & for the Colorado River Valley from 2PM WED – 11AM FRI.
Single digit RH’s & strong north winds will lead to critical fire weather concerns.

TEMPS
High temps will drop about 20 degrees from Wednesday to Thursday. Record low minmum temperatures possible Friday morning.

SPECIAL NOTES:

DAILY FUELS/FIRE POTENTIAL:
Large fire potential will be very high later this week due to gusty offshore winds and extremely low RH. Expect roughly 36-48 hours of strong winds and 72-84 hours of very low RH. The combination windy, dry weather and seasonally dry fuels will allow for extreme rates of spread in new starts Wednesday over Central CA and Thursday – Friday over Southern CA. All fuel types will burn readily as evidenced by the rapid growth of the Briceburg Fire in Mariposa County yesterday. This fire has burned actively overnight despite relatively benign weather conditions and with the weather turning conducive to fire growth, new starts will likely burn at extreme rates of spread. A high risk day has been issued for much of Southern CA for later this week as large fires have developed historically 20% or greater of the time given the outlined weather and fuel conditions. Resource demand will be heavy the rest of the week all across USFS R5.

SANTA ANA WILDFIRE THREAT INDEX: TODAY: GREY-NO RATING
NO RATING: Sundowner winds are either not expected, or will not contribute to
significant fire activity.

MARGINAL: Upon ignition, fires may grow rapidly.

MODERATE: Upon ignition, fires will grow rapidly and will be difficult to control.

HIGH: Upon ignition, fires will grow very rapidly, will burn intensely, and will be very difficult to control

EXTREME: Upon ignition, fires will have extreme growth, will burn very intensely, and will be uncontrollable.

============================================================
THIS DAY IN WEATHER HISTORY:
1961: An early season storm brought thunderstorms to the San Diego Coast. The storms produced gusty winds, small hail, and at least ten reported water spouts between Del Mar and Oceanside. One waterspout moved onshore in Carlsbad to become a tornado, injuring three people when it threw a board through the window. Roofs were ripped off, trees felled and fences downed in Carlsbad and Oceanside. Boats were torn from moorings in Oceanside. Damage was incurred at the Carlsbad SDG&E electric generator plant.

1949: 2.5 inches of snow fell in Idyllwild and two inches fell in Palomar Mountain. Each snowfall is the earliest measurable snowfall for the season on record. A stretch of 140 days without precipitation finally ended in Campo, when 0.02 inches of rain fell.

==================================================================
TROPICAL EAST PACIFIC REPORT:
For the eastern North Pacific…east of 140 degrees west longitude:
Tropical cyclone formation is not expected during the next 5 days.
