Northern California Area

Preparedness Level (PL 4) SYNOP: A weak Pacific trough over the West Coast will cause temperatures to remain 5 to 10 degrees below normal through Wednesday, with 60s to low 70s across the mountains and mid 70s to mid 80s in the valleys. Minimum humidity will be above 20% across most of the region through Wednesday, but it will be in the teens across the deserts. Westerly winds of 20 to 30 mph with gusts to 50 mph will surface across the mountain ridges and desert passes this afternoon through Thursday afternoon. There will be northerly winds of 20 to 30 mph with gusts to 50 mph over much of Santa Barbara County and the Grapevine Thursday and Friday nights. Temperatures will drop to 10 to 20 degrees below normal Thursday and Friday as the trough over the West Coast deepens. Scattered showers will occur over the Sierra and over Southern California Wednesday night through Friday night, with less than a quarter inch of rainfall. The snow level will be around 8,000 feet over the Sierra. Temperatures will warm and humidity will lower across the region this weekend as high pressure approaches the West Coast from the Pacific. Light offshore flow will occur across the area this weekend. FLASH FLOOD POTENTIAL INDEX FOR EXTREME SOUTHWESTERN CALIFORNIANo thunderstorms are expected through Wednesday.                                   MON          TUE

Expect more fall-like weather conditions later this  week, with cooler temperatures and stronger winds. Near normal  temperatures today will cool to around 15 degrees below normal by  the end of the work week with the cooler temperatures carrying over  into the weekend.

 

SPECIAL NOTES: N/A

 

DAILY FUELS/FIRE POTENTIAL:

The potential for large fire will remain low across the region through Friday due to cool and humid conditions away from the deserts. Even though humidity will drop and it will warm this weekend, the large fire threat will remain low due to the absence of significant winds. Light initial attack activity will continue across the region through this weekend.

1985: A tornado was reported around the north shore of the Salton Sea.

 

1982: The remnants of Hurricane Norman tracked northeastward across northern Baja California into Arizona with scattered rainfall amounts up to one inch in the southern mountains and deserts on 9/17 and on this day. This occurred during the strong El Niño of 1982-83.

 

1963: Tropical Storm Jennifer-Katherine made landfall in northern Baja California (the storm has two names because forecasters thought the storm had dissipated, but later reformed). The storm brought heavy rains to the region over a three-day period centered on this day. Up to 6.50 inches of rain fell in the mountains, 3.86 inches fell in San Bernardino, 3.66 inches in Victorville, 3.29 inches in Riverside, 1.44 inches in Palm Springs, and 1.00 inch in San Diego. Disastrous flooding and erosion hit parts of San Bernardino.

 

1939: A heat wave that started on this day and ended on 9/22 preceded the arrival of a tropical storm called “El Cordonazo.” High temperature records of more than 95° occurred at San Diego each day, with the highest temperature reaching 106° on 9/21.

 

1929: A tropical cyclone moved north-northwest just off the west coast of Baja California, dissipating off the coast of northern Baja California. Rainfall of up to four inches occurred in the southern mountains and deserts of Southern California on this day.

 

1924: It was 38° in Escondido, the lowest temperature on record for September.=========================================================================TROPICAL EAST PACIFIC REPORT:

Tropical Weather Outlook

 

For the eastern North Pacific…east of 140 degrees west longitude:

 

The National Hurricane Center is issuing advisories on Tropical

Storm Norma, located south-southwest of the southern tip of the Baja

California peninsula, Mexico, and on Hurricane Otis, located more

than 1000 miles west-southwest of the southern tip of the Baja

California peninsula.

 

A trough of low pressure located about 1300 miles east-southeast of

the Hawaiian Islands is producing disorganized showers and

thunderstorms. Development, if any, of this system should be slow

to occur while it remains nearly stationary during the next few

days.

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

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

 

An area of low pressure is expected to form by the end of the week

south of southeastern Mexico. Some subsequent development

is possible as the system moves slowly west-northwestward.

* Formation chance through 48 hours…low…near 0 percent.

* Formation chance through 5 days…low…20 percent.

DISCUSSION AND 48-HOUR OUTLOOK

——————————

At 600 PM MDT (0000 UTC), the center of Tropical Storm Norma was

located near latitude 21.3 North, longitude 111.2 West. Norma is

moving toward the northwest near 6 mph (9 km/h). The storm is

expected to turn toward the west-northwest by tomorrow and move in

that general direction during the next two days. On the forecast

track, the center of Norma will move nearly parallel to and offshore

of the Baja California peninsula through Tuesday.

 

Maximum sustained winds are near 50 mph (85 km/h) with higher

gusts. Some weakening is forecast during the next 48 hours and Norma

could become a tropical depression by Tuesday.

 

Tropical-storm-force winds extend outward up to 70 miles (110 km)

from the center.

 

The estimated minimum central pressure is 1001 mb (29.56 inches).

 

 

HAZARDS AFFECTING LAND

———————-

RAINFALL: Norma is expected to produce additional rainfall

accumulations of an inch of less over the southern portion of the

Mexican state of Baja California Sur.

 

WIND: Tropical storm conditions are possible within the watch area

tonight or early Monday.

 

SURF: Swells generated by Norma are affecting portions of the coast

of southwestern Mexico and Baja California Sur and will continue

into late Monday or Tuesday. These swells are likely to cause

life-threatening surf and rip current conditions. Please consult

products from your local weather office.
