SYNOP: (NWS SAN DIEGO)
LOW RELATIVE HUMIDITY AND GUSTY OFFSHORE WINDS POSSIBLE NEXT WEEK…

Higher temperatures and low relative humidity will bring elevated fire weather conditions inland through the weekend. For next Thursday and Friday, offshore flow with locally gusty east to northeast winds will be possible. The winds combined with low relative humidity could create elevated fire weather conditions Thursday and Friday for the mountains, valleys and inland Orange County.
Temperatures will be around 5 degrees above normal through Monday, with mid 60s to mid 70s across the mountains and 80s to low 90s in the valleys.

· Minimum humidity will be mainly in the single digits and teens away from the coastal areas through Tuesday.

· Winds will be light through Monday.

· Southwest to west winds of 20 to 30 mph with gusts to 50 mph will surface across the desert passes Tuesday afternoon through Wednesday morning.

· Temperatures will cool to near normal Tuesday through the end of next week.

· Minimum humidity will increase to 15% to 30% Wednesday and then decrease back into the single digits and teens late next week.

· Gusty northeast winds will surface across the mountains and below the canyons and passes of Southern California Thursday morning through Thursday mid-afternoon.

· Winds will become light late Thursday afternoon through Friday.

KEY POINTS
● Elevated fire weather conditions in the deserts and desert slopes of the mountains due
to low humidity values and breezy southwest winds through the weekend.

● Humidity values will increase slightly over the weekend.

● Critical fire weather conditions on Thursday and Friday due to gusty east to northeast
winds and low humidity values in the mountains, valleys, and Inland Orange County.

Elevated Fire Weather – Deserts and Desert Mountain Slopes
High Confidence Low humidity values and gusty northwest winds
Details
– What: Breezy winds from the northwest with gusts to 30 mph and relative humidity values of 5 to 10 percent in the afternoons. Humidity values will slowly increase in the late afternoons as onshore flow spreads
inland.

– Where: Deserts and desert mountain slopes
– When: Through this weekend

Critical Fire Weather – Mountains, Valleys, Inland Orange County
Moderate
Confidence
Gusty east to northeast winds and low humidity values
Details
– What: East to northeast winds of 15-25 mph with local gusts to 50 mph combined with low humidity values will create critical fire weather conditions. Humidity values will be 5-10% in the mountains and 15-20% in
the valleys and inland Orange County.

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

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
Expect plenty of sunshine and dry conditions with temperatures close to their seasonal normals over the weekend. Minimum RH`s will remain below 15 percent over the next 7 days. There will be some gusty north winds down the Colorado River on Sunday. Temperatures will increase a degree or two through early
next week. Next weather system is expected by mid-week mainly bringing gusty winds and a decrease in temperatures.

DAILY FUELS/FIRE POTENTIAL:
The potential for large fire will be low across most of the region through the end of next week. However, gusty offshore winds will bring an elevated risk for large fire across windy areas of Southern California Thursday. Fuel moisture will continue to drop through the end of next week as very dry conditions continue. Light initial attack activity will continue across the area 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.

Amounts ranged from 0.75 inch at the coast to two inches in the mountains. 2.14 inches fell at Camp Pendleton and 0.69 inch fell at San Diego. Minor flood damage occurred.

1985: A rapidly moving storm system brought 50 knot wind gusts to Catalina Island, causing nearly 100 boats to pull lose from or drag their moorings.

1980: It was 85° in Big Bear Lake and 101° in Victorville, each the highest temperature on record for October. In Victorville this also occurred two days previous on 10/3.

TROPICAL EAST PACIFIC REPORT:
For the eastern North Pacific…east of 140 degrees west longitude:

Showers and thunderstorms have decreased substantially during the past several hours near a low pressure system located about 1200 miles west-southwest of the southern tip of the Baja California peninsula. Some development of this system is still possible over the next day or two before it interacts with, and possibly merges with, another disturbance west of it. The low is expected to move northwestward at about 10 mph during the next couple of days.

* Formation chance through 48 hours…low…30 percent.
* Formation chance through 5 days…low…30 percent.

Another low pressure system located just west of the disturbance mentioned above, about 1700 miles southwest of the southern tip of the Baja California peninsula, continues to produce disorganized shower and thunderstorm activity. Development of this system is not likely before it interacts or merges with the larger disturbance located to its east during the next couple of days.

* Formation chance through 48 hours…low…10 percent.
* Formation chance through 5 days…low…10 percent.
