SYNOP: (NWS SAN DIEGO)
ELEVATED FIRE WEATHER CONDITIONS FOR THE MOUNTAINS…DESERTS…AND INLAND VALLEYS FOR TODAY…

…MODERATE STRENGTH SANTA ANA WIND EVENT FOR THURSDAY INTO FRIDAY

Weak offshore flow this morning will become weak onshore today, then strengthen for Tuesday and Wednesday with gusty southwest to west winds in the mountains and deserts. Elevated fire weather conditions for the mountains, deserts, and inland valleys today, will shift to the deserts on Tuesday and Wednesday. The strengthening onshore flow will spread cooling and higher coastal humidity inland. With much lower inland humidity and moderate strength Santa Ana winds, critical fire weather conditions will develop on Thursday morning, especially for the mountains, inland valleys and inland Orange County, and below the Cajon and Banning Passes. Lowest daytime humidity of 5 to 10 percent will continue for inland areas on Friday and Saturday. Santa Ana winds will begin to weaken on Friday with weaker and more localized winds for Saturday. Critical fire weather conditions will continue into Friday with at least elevated conditions for Saturday.

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.

· West winds 20-30 mph with gusts to 40 mph Tuesday in the Kern County Mountains, Antelope Valley and Banning Pass eastward into the desert.

· Northeast winds of 25-35 mph developing Wed. afternoon in the Sierras, Inyo National Forest spreading southward Wed. night.

· Offshore winds 20-30 mph with gusts to 40-50 mph possible late Wed. night or Thursday morning across Southern CA. Offshore winds weakening Thursday afternoon before ending altogether Friday evening.

· Minimum humidity will drop into the 5-10% range across Southern CA Thursday into Saturday. Very poor recovery Thursday and Friday nights.

Strong Winds – Deserts and Desert Mountain Slopes

High Confidence Gusty west to northwest winds
Details

– What: West to northwest winds of 15-20 mph with gusts to 35-40 mph. Strongest winds will be on Wednesday.

– Where: Deserts and desert mountain slopes
– When: Tuesday and Wednesday

Critical Fire Weather – Mountains, Desert Mountain Slopes, Valleys, & Inland Orange County
High Confidence Gusty east to northeast winds and low humidity values

Details
– What: East to northeast winds of 15-25 mph with gusts 35-45 mph, local gusts to 50 mph combined with low humidity values will createcritical fire weather conditions. Humidity values will be 5-10% in the mountains and 10-15% in the valleys and inland Orange County.

– Where: Mountains, Desert Slopes, Valleys, and Inland Orange County
– When: Thursday and Friday

KEY POINTS
● On Thursday and Friday, a moderate Santa Ana event with gusty east to northeast winds
and very low relative humidity will create critical fire weather conditions, especially in
the mountains, desert mountain slopes, valleys, and Inland Orange County.

● Elevated fire weather conditions will continue through the week, with gusty west to
northwest winds expected Tuesday and Wednesday.

● Below freezing low temperatures are possible in the mountain valleys and High Desert
Saturday morning.

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
A mild and tranquil weather pattern continues Monday through Tuesday. A dry cold front will sweep across the region Wednesday and Thursday bringing gusty winds and significantly cooler temperatures. Minimum afternoon humidity levels will range from the single digits in the lower elevations to around 15-20
percent along the higher terrain over the next 7 days. With gusty winds and low RH`s fire weather conditions will be elevated Wednesday and Thursday.

DAILY FUELS/FIRE POTENTIAL:
There will be an elevated large fire potential later this week due to gusty winds and very low RH over a wide area. The previous offshore wind event was largely confined to the highest elevations. While this coming event may be of similar strength, there may be some higher gusts in the valleys this time around. An extended period of very low RH will be one of the primary threats later this week with at least 72 hours of single digits or teens likely later this week. Any start will show extreme rates of spread in windy areas with active burning likely at night. Dead fuel moisture readings are uniformly low across the region with values residing in the 90-95th percentile. Live fuel moisture is near, or just above, critically low levels. Thus, fires will readily burn through both live and dead fuels of all diameters. Resource demand is likely to be heavy later this week as a large area will be impacted by the winds and low RH. Look for lighter IA and resource demand early next week.

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.

DAYS TWO THROUGH SEVEN…Monday through Saturday

Much colder temperatures will arrive across Utah Wednesday as a powerful cold front cross the region. By Thursday temperatures are expected to run about 20 to 30 degrees below average. Locations that have not yet experienced a hard freeze, including the Wasatch Front, are likely to experience a hard freeze by late this week.

Moisture is overall expected to be limited with this storm system, however temperatures will be cold enough to support snow level falling to the valley floors.

Lake effect precipitation is possible south and east of the Great Salt Lake, mainly Thursday morning. However there remains plenty of uncertainty with respect to potential intensity and placement.

============================================================
THIS DAY IN WEATHER HISTORY:
1997: Very intense thunderstorms hit the Inland Empire. In Hemet, 1.65 inches of rain fell in just 75 minutes, and 0.31 inch fell in just three minutes. Floods and debris flows resulted, causing $2.5 million in damage. Large trees, mud, and boulders were swept down canyons. Homes and apartments were flooded in north San Bernardino and Highland. Up to two inches of rain fell in one hour on Holcomb Hill near Running Springs, the rapid runoff loosened debris associated with a recent burn scar and sent a six-foot wall of mud and debris flowing downhill. The flow damaged 29 buildings, 14 cars and forced a helicopter rescue of four teenagers. Big Bear Lake recorded 0.5 inch of snowfall, the earliest measurable snowfall on record.

1977: Hurricane Heather recurved with the remnants tracking across northern Baja California into Arizona. There was rainfall up to two inches in the southern mountains and deserts on 10/6 and on this day. This occurred during the El Niño of 1977-78.
