National Preparedness Level 3 

Southern California Area

Preparedness Level: (PL 3) 

Northern California Area

Preparedness Level (PL 3) SYNOP:

***Offshore winds expected later this week***

***Dry and warm Friday into the weekend***

The cutoff low pressure area which brought cool weather to the region is lifting northeastward which will be replaced by high pressure aloft and offshore pressure gradients. This will lead to a strong warming trend through Saturday. Today, highs will be 10-15 degrees warmer across the valleys and lower foothills with 80s common across Southern California. By Friday and Saturday, highs will be close to the 100 degree mark over much of interior Southern California below 3,000 feet. Minimum RH will fall into the 7-12% range by Friday afternoon with poor RH recovery expected Friday night. Northeast winds of 15-25 mph with gusts to 40 mph will be possible through the passes and canyons of Southern California. At this time, the strongest winds look to occur over Ventura and Northern Los Angeles County on Friday. The offshore winds will likely continue into Saturday morning, but wind speeds should be a bit weaker. Onshore flow should bring cooler weather Sunday into Monday. Warmer weather looks to return next Tuesday along with light offshore flow. No precipitation is expected through the period.

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

Expect a warming trend into the weekend, with  afternoon humidities falling under 10 percent for the deserts, 15  percent for the mountains, and overnight recovery around 25 to 30  percent for southern portions of the area, 40-50 percent in the  Great Basin. Gusty winds possible, mainly for the Colorado River  Valley on Friday, with more widespread gusty winds possible Sunday  into Monday with a cold front expected to move south across the  area.

 

SUNDAY AFTERNOON-MONDAY MORNING

Potential Wind Gusts (could still change significantly, stay tuned)

Ahead of the front: southwest gusts 20-30 MPH

Behind the front: northwest gusts 45-65 MPH

Preliminary Cold Front ETA (could still change significantly, stay tuned)

2pm-5pm: Bishop, Tonopah, Ely

5pm-8pm: Furnace Creek, NNSS, Caliente

8pm-11pm: Ridgecrest, Pahrump, Las Vegas, Lake Mead, Mesquite

11pm-2am: Ft. Irwin, Lake Mohave, Bullhead City, Colorado City

2am-5am: Twenty-nine Palms, Yucca Valley, Lake Havasu, Kingman

 

MONDAY

Widespread northerly wind gusts 30-50 MPH, gradually diminishing through the day and evening.

 

TUESDAY MORNING

Localized northerly wind gusts 25-35 MPH, strongest along the Colorado River Valley.

 

SPECIAL NOTES:

NOAA National Weather Service outlook for mid to late October

  • Very warm conditions all areas including coast for October 8-14
  • Possible Santa Ana wind October 8-11 with surface high pressure over Great Basin.
  • Weaker Santa Ana October 12-16 but continued warm conditions
  • Surface high pressure shifts over Central Plains, pattern change brings the storm track into the Pacific Northwest with only a chance of showers SoCal, from October 15-20 with a frontal passage. Warmer than normal conditions prevail inland areas for October 15-20 and possible Santa Ana wind event.
  • Battle between east Pacific/Pac NW upper trough (storm) and weaker high pressure aloft for cooling trend and possible precipitation late October

 

DAILY FUELS/FIRE POTENTIAL:

Large fire potential will climb to elevated levels across the foothill and valley areas of Southern California Friday. Gusty winds, very warm temperatures and low RH will allow for extreme rates of spread in the passes Friday. Active burning may continue well into Friday night as RH recovery will be non-existent over much of Southern California. Additionally, although winds will be light over the central part of the state, very warm temperatures and low RH is also expected over interior portions of Monterey and San Luis Obispo Counties. All of these areas will see very high ignition components and fire spread will be aggressive, even in non-windy areas. Dead fuel moisture is below normal over much of the southern part of the state and live fuels are critically dry over some areas away from the coast. Large fire potential will drop Sunday and Monday in response to the cooler weather, but shifting winds may cause any ongoing fires to show erratic behavior as sea-breeze conditions return. Moderate IA and resource demand is likely Friday into the weekend.
