SYNOP: (NWS SAN DIEGO)
RED FLAG WARNING THROUGH THURSDAY AFTERNOON FOR STRONG GUSTY
WINDS AND LOW HUMIDITY FOR MOUNTAINS…VALLEYS…AND INLAND
ORANGE COUNTY AND THROUGH THIS AFTERNOON FOR ORANGE COUNTY COASTAL
AREAS…

Offshore flow will strengthen this morning, then gradually weaken for tonight through Thursday night. The strongest and most widespread winds are expected today. Winds are not expected to be quite as strong for tonight, then will decrease in coverage on Thursday and gradually weaken from the morning through the afternoon. The winds combined with very low humidity will bring critical fire weather conditions through Thursday afternoon for mountains, valleys, and inland Orange County. Weaker offshore flow with only a very slow recovery in humidity will follow for Friday and Saturday. Weak onshore flow for Sunday into early next week will slowly spread cooling and higher coastal humidity inland.

Likely time of strongest winds… This morning through 2100 this evening
· Strongest winds…30-40 mph, gusts 75+ mph…LA County, VTU, Cajon Pass 25-35 mph, gusts 65+ mph…OC, Inland Empire 25-35 mph, gusts 55 mph (mountains 75 mph)…San Diego Co.

· Lowest RH…widespread minimums 2-7% today and Thursday below 7,000 feet. No recovery tonight

· Gusty winds over 50 mph still possible tonight into Thursday morning before winds subside in the afternoon and evening.

· It will be a “cold” Santa Ana wind event with temperatures in the 50s in the mountains to the 70s at lower elevations.

· Light winds, warmer temperatures this weekend with highs back in the 80s in the valleys. Daytime RH will continue to be low away from the coast.

· No rain next 2 weeks.

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
Gusty north winds and low humidity will bring critical fire conditions to the Colorado River Valley through late
afternoon, and a Red Flag Warning remains in effect. Much warmer and dry weather is expected beginning Thursday and lasting through the weekend.

CONFIDENCE AND DETAILS
Colorado River Valley/Eastern San Bernardino County
HIGH Confidence Dangerous boating conditions due to strong winds and significant wave activity.
Extreme fire behavior and rapid fire growth.

MODERATE Confidence Loose or unsecured objects may be blown away.

Details:
TODAY
LAKE MEAD/LAKE MOHAVE/LAKE HAVASU/EASTERN SAN BERNARDINO COUNTY
North wind 25 to 35 gusts to 45 mph, before starting to weaken in the late afternoon.

Clark/Southern Nye/San Bernardino County Deserts
HIGH Confidence First freeze of the year will bring the end to the growing season.
Sensitive plants left outdoors will be killed.

Details:
THURSDAY MORNING
First freeze of the season likely to impact:
Much of the Mojave Desert, including parts of Las Vegas Valley, and San Bernardino County.
TEMPERATURES
Lows 25 to 30.

DAILY FUELS/FIRE POTENTIAL:
Large fire potential will be extreme today due to strong winds, very low humidity and critically dry fuels. As has been seen with new starts the past few days, all fuel types are burning readily and completely with long range spotting and near total consumption. Expect extreme rates of spread today which will challenge resources. Strong winds near higher terrain may limit the availability of fixed wing aircraft, especially this morning. Expect roughly 36 hours of extreme fire weather before conditions moderate Thursday afternoon. A return of light diurnal winds Friday may result in shifting fire fronts. Expect heavy IA and resource demand the next two days with lighter demand over the weekend.

SANTA ANA WILDFIRE THREAT INDEX: TODAY: RED HIGH

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.
