SYNOP: (NWS SAN DIEGO)
KEY POINTS
• Elevated fire weather conditions briefly Friday morning due to gusty winds affecting the San Bernardino Mountains and the Inland Empire.

• Gusty west winds in the mountains and deserts through Friday morning, with peak gusts to 50 mph.

• Locally elevated surf conditions possible this weekend, along with increased rip current danger, mainly in San Diego County.

• Weak to moderate Santa Ana conditions Sunday through Tuesday. Another Santa Ana event is possible starting next Thursday.
________________________________________
CHANGES FROM PREVIOUS BRIEFING
• Santa Ana wind event has trended slightly weaker. Confidence on timing has increased, but strength remains low. Inland temperatures above seasonal averages for Monday and Tuesday. Confidence increasing for another Santa Ana event starting next Thursday.

Lower level flow will be onshore through Saturday night and except weak northerly near the San Bernardino County mountains for this morning and Saturday morning. Weak offshore flow will develop on Sunday and become a little stronger for late Sunday nigbt into Monday morning with gusty northeast winds to 35 mph near the coastal slopes of the mountains. Weaker northeast winds of 25 mph or less will then continue into Tuesday morning. Lowest daytime humidity for inland areas will fall to around 10 percent on Monday
and Tuesday with elevated to locally critical fire weather conditions for the mountains and inland valleys on Monday and elevated conditions for those areas on Tuesday. Weak onshore flow on Wednesday and Thursday will spread cooling and higher coastal humidity inland.

Onshore (west to northwest wind) winds through Friday as weather system passesby to the north. Desert slopes impacted. Wind shift to north in the deserts.

Santa Ana winds begin Sunday morning and dry air begins to arrive

Winds (northeast) increase Sunday night into Monday morning

WeakSanta Ana wind overall –elevated fire weather danger (no Red Flag at this time)

Temperatures warm to much above average for Monday (to coast) into Wednesday

Much less wind but dry and warm on Tuesday and Wednesday (hottest inland)

Another Santa Ana wind for Thursday and Friday (next week)

Potential for moderate winds (stronger) and high fire danger

Sunday and Monday: Wind gusts 35 to 50 mph for most wind prone areas of Santa Ana and San Bernardino mountains and isolated in San Diego mountains –most areas wind gusts 10 to 20 mph

Humidity values in the teens, lowest on Monday and Tuesday. Poor recoveryat night for Sunday night.

Very warm days Monday through Friday but mild nights

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
North winds will linger this morning with the strongest winds along the Colorado River Valley continuing through the afternoon. Temperatures will be cooler and clouds will be on the increase. A brief warm up is expected on Saturday before another cold front drops temperatures back below normal Sunday with more north winds. A slight warming trend follows for Monday through Wednesday then temperatures drop again Thursday behind another front. Otherwise, periods of high clouds will pass over the area but no precipitation is expected.

DAILY FUELS/FIRE POTENTIAL:
The potential for large fire will be low across most of the region through Sunday as cool and fairly humid conditions continue. However, strong north winds will allow for rapid rates of spread and long range spotting if an ignition were to occur in a windy location like the Real Fire in Santa Barbara County. Computer models continue to show the offshore wind event for early next week to be weaker and of shorter duration so “High Risk” Days are no longer needed for the Southern California PSAs. Expect light initial attack activity across the region through the end of 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.
