National Preparedness Level 3 

Southern California Area

Preparedness Level: (PL 3) 

Northern California Area

Preparedness Level (PL 4) SYNOP: *** Near-critical fire weather conditions likely Saturday into Sunday due to moderate Santa Ana Winds **

***Gusty north winds Santa Barbara County, I-5 Corridor next two nights***

***Offshore winds, very warm temperatures, low RH this weekend***

A trough diving into the northern Rockies and Great Basin will generate gusty winds, warm temperatures and low RH over the next few days. Today, northwest winds of 15-25 mph will develop this afternoon along the central coast and the Kern County Mountains. An increasing northerly pressure gradient will, in turn, lead to gusty north winds of 15-30 mph in southern Santa Barbara County and the I-5 Corridor into the Santa Clarita Valley and adjacent mountain areas tonight into Friday morning. Local RH recovery will be poor in Santa Barbara County and higher elevations of the eastern Angeles N.F. tonight and again Friday night. There may be a lull in winds Friday afternoon, but the winds will ramp back up in these areas Friday night into Saturday morning. Afterward, the winds will transition to the northeast through the day Saturday which will favor Ventura and northern Los Angeles County. By Saturday afternoon or evening, northeast winds of 20-30 mph with gusts to 40 mph can be expected. The winds will likely peak in strength Saturday night through noon Sunday before slowly subsiding Sunday afternoon and evening. Minimum RH will fall into the 5-10% range over a wide section of Southern California below 7,000 feet. Temperatures west of the mountains will climb toward 90 degrees all the way to the coast Saturday through Monday. A return of onshore flow may lead to cooler and more humid weather beginning next Tuesday.

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

Fall-like weather pattern is expected through the  weekend with dry conditions, sunny skies, and periods of breezy  conditions. Saturday will be the windiest day as a dry cold front  passes through the area. Strong winds will continue down the  Colorado River Valley Sunday while elsewhere winds will be weaker.  Temperatures warm early next week under high pressure.

 

SPECIAL NOTES:

NOAA National Weather Service outlook for mid October to early November

 

  • Santa Ana wind October 14-16, near average inland but above normal on the coast (storm track across northern Great Basin).
  • Pattern change brings the wet and cool active storm track into the Pacific Northwest – October 17-28 with only a chance of showers in Socal with a frontal passage. Cooler than normal conditions prevail Socal inland areas and near average on the coast.
  • Upper level high pressure could rebuild October 22 to November 3, and bring dry conditions and above normal temperatures for the coast or possible heat wave. These conditions could begin with Santa Ana winds.

 

DAILY FUELS/FIRE POTENTIAL:

Large fire potential will be extremely high this weekend, especially in the hills above highway 126, the Santa Clarita Valley and Canyon County of northern Los Angeles County where winds will be strongest. Expect extreme rates of spread in these areas with long range spotting and rapid uphill runs in the windy areas. Fuel moisture is at record, or very close to, record low readings in both the 100 and 1,000 hour dead fuels across Southern California. Hot, dry weather will allow both live and dead fuel beds to be highly receptive to ignition. Live fuels will show little resistance to fire spread as evidenced by the Canyon 2 fire which had extreme rates of spread through all fuel types. Although winds may not be quite as strong as earlier this week, this event may last a bit longer with the winds slowly ramping up Saturday before slowly abating Sunday afternoon. IA and resource demand will likely be heavy this weekend before turning light 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.

 

1987: A prolonged period of showers from the remnants of Hurricane Ramon started on 10/5 and ended on this day. Rainfall amounts ranged from 0.75 inch at the coast to two inches in the mountains. 2.14 inches fell at Camp Pendleton, 2.08 inches in Fallbrook and 0.69 inch fell at Lindbergh Field. Minor flood damage occurred.

 

1985: A thunderstorm produced wind gusts close to 80 mph near Encinitas. Tree and power pole damage was widespread, and the roof was ripped off a duplex.

 

1950: Strong high pressure brought record high temperatures. It was 93° in Idyllwild, the highest temperature on record for October. This also occurred on 10/1/1980.

 

 

1924: An early season cold snap gripped Southern California from 10/11 to 10/13. On this day it was 34° in Santa Ana, the lowest temperature on record for October. This also occurred on 10/21/1949 and on 10/31/1935. It was 32° in Escondido, the earliest freezing temperature of the season on record. It is also the lowest temperature on record for October, which also occurred the next day on 10/13.

 

1889: A monsoon-type thunderstorm brought 7.58 inches of rain to Encinitas in eight hours from 10 pm this day to 6 am on 10/13. 0.44 inch fell in San Diego.=========================================================================TROPICAL EAST PACIFIC REPORT:

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

 

A broad area of low pressure centered about 700 miles south of the

southern tip of the Baja California peninsula is producing

disorganized showers and thunderstorms. Strong upper-level winds

will likely limit development of this system for the next couple of

days, but some gradual development could occur thereafter while the

system moves generally westward at 10 to 15 mph.

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

* Formation chance through 5 days…low…20 percent.
