***Strong offshore winds Monday***

***Very dry Monday and Tuesday***

A Pacific trough over the Great Basin will bring westerly winds of 20 to 30 mph with gusts to 50 mph to the mountain ridges and desert passes through this afternoon. This trough will also cause significant cooling across the region today, with 60s to low 70s across the mountains and mid 70s to mid 80s in the valleys. Humidity will increase throughout the day. Northeast winds of 20 to 40 mph with gusts to 60 mph will surface across the mountains and below the canyons and passes of Southern California Monday morning through Monday afternoon as a strong surface high sets up over the Great Basin. These offshore winds will decrease Monday evening and become light by Tuesday morning. Maximum temperatures will cool to the mid 50s to mid 60s across the mountains, but warm to the upper 70s and 80s in the valleys Monday. The entire region will see a few degrees of warming Tuesday as a weak ridge of high pressure aloft moves over California from the Pacific Ocean. Minimum humidity will be mainly in the single digits and teens both Monday and Tuesday. A Pacific trough will deepen over the West Coast bringing cooling and an increase in humidity Wednesday through the end of this week. Westerly winds of 15 to 25 mph with gusts to 40 mph will surface across the wind prone mountain and desert areas Wednesday through the end of this week.

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

A strong cold front will move through the area late  today through tonight. Gusty north winds will start to push into  northern portions of the area this afternoon, spreading south  overnight. Widespread wind gusts over 40 mph are likely with gusts  to 60 mph possible in some areas. Much cooler temperatures are  expected Monday behind the front while winds start to decrease late  in the day. Dry conditions and warming temperatures can be expected  Tuesday and Wednesday with some southwesterly breezes Wednesday.

 

SUNDAY AFTERNOON-MONDAY MORNING

Potential Wind Gusts

Ahead of the front: southwest gusts 20-30 MPH in Mohave County

Behind the front: North gusts 40-50 MPH, with 60+ in the Colorado River Valley north of Needles

 

Preliminary Cold Front ETA

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

2am-5am: Twentynine Palms, Yucca Valley

 

MONDAY

Widespread northerly wind gusts 30-50 MPH, diminishing through evening.

 

SPECIAL NOTES: UPDATE FOR SANTA ANA EVENT

Changes Since Last Briefing:

Fire Weather Watches and Red Flag Warnings have been issued. Check our detailed hazards page or weather.gov/sandiego for the latest watches/warnings.

 

Weather Summary

Moderate to Strong Santa Ana winds will bring very dry and windy weather to the region late Sunday night (10/8) through early Tuesday (10/10). Critical fire weather conditions are likely for portions of the coastal foothills/valleys/passes.

 

​ ​Weather Threats, Impacts and Locations:

  • Critical fire weather conditions due to low humidity, dry fuels and strong and gusty winds:
    • San Bernardino, Riverside and San Diego County mountains, foothills and passes (including I-15 and I-215 Cajon Pass, I-10 San Gorgonio Pass, I-8 Pass).
    • Santa Ana Mountains/Foothills and inland Orange County (including Highway 91 corridor and pass).
  • Strong winds resulting in hazardous cross-winds for high profile vehicles. Broken tree limbs and debris on the roadways.
  • Chance of power outages.

Forecast Winds:

  • Areas of northeast winds 25-35 mph with gusts to 55 mph.

Forecast Relative Humidity:

  • Humidity falling to 5-10 percent with poor recovery for the mountains and far inland valleys Monday night, then falling to 8-12 percent Tuesday.

Wind Timing:

  • Moderate to Strong winds late Sunday night through late Monday morning (with strongest winds during the early to mid morning hours Monday), then winds weak to moderate strength Monday afternoon through late Monday night, becoming mainly weak Tuesday morning.

 

Outlook:

Winds will turn back onshore late Tuesday and humidity recovery Tuesday night will be better, with humidities continuing to increase Wednesday and Thursday.

 

DAILY FUELS/FIRE POTENTIAL:

The potential for large fire will be low today as significant cooling and a large increase in humidity takes place. Strong offshore winds along with single digit humidity will bring a high risk for large fire to Southern California from the mountains westward Monday. Both the dead and live fuels are very dry so new ignitions will be likely and initial attack activity will most likely be heavy. The strong, dry offshore winds will likely cause rapid rates of spread and long range spotting on any new ignitions Monday. The large fire threat will decrease significantly on Tuesday as winds become light. The potential for large fire will become low Wednesday through the end of this week as conditions become cool and humid.

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.
