Preparedness Level: (PL 3) 

Northern California Area

Preparedness Level (PL 4) SYNOP: A weakening Pacific trough over the West Coast will bring a couple of degrees of warming to the area each day through Monday. Maximum temperatures will be around 10 degrees below normal today, with mid 60s to mid 70s across the mountains and mid 70s to mid 80s in the valleys. Temperatures will warm to near normal by Monday. Significant cooling will occur Tuesday through Thursday as the trough over the West Coast deepens. Minimum humidity will be above 20% across the region through Thursday, except there will be teens across the deserts at times. Westerly winds of 15 to 25 mph with gusts to 40 mph will surface across the wind prone mountain and desert areas through this evening. Strong westerly winds will surface across the mountain ridges and desert passes Monday afternoon through Thursday and there will be strong northerly nighttime winds across much of Santa Barbara County and the Grapevine Tuesday through Thursday. 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:

Cool and humid conditions will cause the potential for large fire to remain low across the region through the forecast period. However, rapid rates of spread and long range spotting will be possible if an ignition were to occur across the desert slopes due to strong winds, especially during the middle of next week when winds will be the strongest. The dead fuel moisture will be fairly high for this time of year due to humid conditions over the past week and continued humid conditions. Expect light initial attack activity across the region through the forecast period.

2015: A Pacific trough tapped into remnant moisture from tropical cyclone Linda on this day. One to two inches of rain was common across the entire region. Widespread urban flooding resulted, and led to a major traffic jam during the morning commute in LA and Orange County. A debris flow hit Silverado Canyon. An impressive 2.39 inches fell in Los Angeles on this day, and 1.21 inches fell in San Diego, each the second highest daily amount for any day in September. In San Diego this value missed the wettest September day in history by only 0.02 inch (wettest September day was 1.23 inch on 9/30/1921).

 

1979: The temperature soared to 104° in La Mesa on this day, the hottest day of the year, and the 5th hottest day of the 1970s.

 

1910: The remnants of a tropical cyclone moved north, bringing heavy rains to Santa Barbara County. Over four inches fell in Ojai and over two inches fell in Santa Barbara. Only a trace fell in Los Angeles=========================================================================TROPICAL EAST PACIFIC REPORT:

DISCUSSION AND 48-HOUR OUTLOOK

——————————

At 700 PM CDT (0000 UTC), the center of Tropical Storm Max was

located inland over southern Mexico near latitude 16.8 North,

longitude 98.7 West. Max is moving toward the east near 8 mph (13

km/h), and a turn toward the east-northeast is expected by tonight.

On the forecast track, the center of Max will move farther inland

over southern Mexico tonight.

 

Maximum sustained winds have decreased to near 70 mph (110 km/h)

with higher gusts. Rapid weakening is forecast, and Max is

expected to weaken to a tropical depression later tonight and

dissipate over southern Mexico on Friday.

 

Tropical-storm-force winds extend outward up to 45 miles (75 km)

from the center.

 

The estimated minimum central pressure is 992 mb (29.29 inches).

 

 

HAZARDS AFFECTING LAND

———————-

RAINFALL: Max is expected to produce total rainfall accumulations

of 5 to 10 inches in the Mexican state of Guerrero and western

portions of the state of Oaxaca. Maximum amounts locally in excess

of 20 inches are possible over coastal areas of Guerrero. These

torrential rains may produce life-threatening flash floods and

mudslides.

 

WIND: Tropical storm conditions will continue over portions of the

warning area through late tonight.

 

STORM SURGE: A dangerous storm surge is expected to produce

significant coastal flooding in areas of onshore flow to the

southeast of the center of Max. Near the coast, the surge will be

accompanied by large and destructive waves.
