Preparedness Level: (PL 3) 

Northern California Area

Preparedness Level (PL 4) SYNOP: Temperatures will gradually warm through early next week as a Pacific trough over the West Coast weakens. Maximum temperatures will be in the upper 60s and 70s across the mountains and upper 70s and 80s in the valleys today. The Pacific trough over the West Coast will strengthen bringing significant cooling to the area Wednesday through the end of next week. Minimum humidity will be above 20% away from the deserts and there will be good humidity recovery at night through the end of next week. Westerly winds of 20 to 30 mph with gusts to 50 mph will surface across the wind prone mountain and desert areas Monday afternoon through the end of next week. There will be northerly winds of 20 to 30 mph with gusts to 50 mph across much of Santa Barbara County and the Grapevine both Thursday night and Friday night. Scattered showers with light rainfall totals will be possible over the Sierra and parts of Southern California Wednesday night through Friday afternoon. FLASH FLOOD POTENTIAL INDEX FOR EXTREME SOUTHWESTERN CALIFORNIA

SPECIAL NOTES:

BI-MONTHLY FUELS DISCUSSION

For Southern and Central California

Updated: Thursday, September 14th, 2017

Next Routine Update: Thursday, September 28th, 2017

 

General Discussion:

After a spell of record high temperatures at the end of August into early September, a tropical storm, Lidia,

brought some moisture to the region earlier this month. The monsoon, which has been absent for much of the

summer, was finally pulled far enough west to bring wetting rains to portions of the district. Although

precipitation was light for the most part, an increase in precipitable water and relative humidity kept fine fuel

moisture from changing too much during the middle of the month.

 

Fuel moisture conditions at the current time continue to be a mixed bag. In general, coastal areas continue to

enjoy above normal fuel moisture while inland, live fuels are approaching critically dry levels in small diameter

brush and small plants. Heavier riparian fuels are above normal in terms of fuel moisture, likely due to the

moisture over the past two weeks. Dead fuel moisture is still quite low away from the coast, but percentages

have climbed above the critical level across many areas recently.

 

An amplified pattern is expected to develop across much of the western half of the country during the next two

weeks. A trough may stall over the West Coast and Great Basin which may keep temperatures below normal

during much of the next two weeks. Some windy periods, including some offshore winds, may arrive during

the last part of the month which may push fuel moisture levels downward once again.

 

DAILY FUELS/FIRE POTENTIAL:

The potential for large fire will be low across the region through the end of next week as cool and humid conditions continue. The humid conditions will keep the dead fuel moisture high and initial attack activity will remain light across the region through the end of next week.

The easterly flow collided with the sea breeze in the late morning and afternoon, producing rare severe thunderstorms from San Diego to the Inland Empire. Downburst winds downed or damaged hundreds of trees and caused power outages and structural damage in El Cajon, Spring Valley, Clairemont and Kearny Mesa. Ten aircraft were heavily damaged at Montgomery field by winds in excess of 50 mph. 30 buildings were damaged in the city of San Diego. A funnel cloud was observed just north of Big Bear Lake.

 

1969: A heavy thunderstorm hit Barstow and flash floods flowed through the streets. Water washed into 40 homes. Thunderstorms around San Bernardino dropped numerous lightning strikes, which caused power failures. Power poles were set on fire. Several forest fires were also set, but quickly contained.

 

1929: A tropical air mass enveloped Southern California. The Meteorologist in Charge at San Diego reported temperatures of 111° in the coastal valleys. A reading of 94° was reported at San Diego at 4 am on 9/17.

 

1909: It was 100° in San Diego, the hottest day since 9/22/1883 (26 years). It occurred at 9 am=========================================================================TROPICAL EAST PACIFIC REPORT:
