National Preparedness Level 5 

Southern California Area

Preparedness Level: (PL 3) 

Northern California Area

Preparedness Level (PL 4) SYNOP: There will be little change in temperature through Tuesday as a weak trough remains over the West Coast. Maximum temperatures will be in the mid 60s to mid 70s across the mountains and upper 70s and 80s in the valleys. A Cooling trend will occur Wednesday through the end of this week as the trough over the West Coast deepens. Temperatures will be well below normal Thursday and Friday. Scattered showers with light rainfall totals will be possible over the Sierra and over Southern California Wednesday night through Friday afternoon. Minimum humidity will remain above 20% away from the deserts through the end of this week. Westerly winds of 20 to 30 mph with gusts to 50 mph will surface across the wind prone mountain and desert locations Monday afternoon through Thursday afternoon. Northerly winds of 20 to 30 mph with gusts to 50 mph will surface across Santa Barbara County and the Grapevine Thursday and Friday nights. A ridge of high pressure will approach the West Coast from the Pacific causing warming and drying next weekend. Gusty offshore winds will be possible across Southern California next weekend. FLASH FLOOD POTENTIAL INDEX FOR EXTREME SOUTHWESTERN CALIFORNIA

No thunderstorms are expected through early next week.

Weather conditions over the next several days will be  quiet with occasional clouds, afternoon breezes and seasonal  temperatures. A weather change is in the making for later this week  as a strong trough brings cooler, windier weather to the area.

 

SPECIAL NOTES: N/A

 

DAILY FUELS/FIRE POTENTIAL:

Cool and humid conditions will keep the potential for large fire low across the region through the end of this week. The offshore wind event across Southern California looks weak and will most likely not increase the large fire threat much next weekend. Light initial attack activity will continue across the region through next weekend.

2008: A landspout tornado was observed over Johnson Valley (east of Lucerne Valley), but no damage was reported.

 

1984: A tropical air mass lasting two weeks and high sea surface temperatures led to record minimum temperature records set each day except one at San Diego starting on 9/4 and ending on 9/19. Low temperatures ranged from 73° to the highest minimum of all time of 78° on this day and on 9/9. The high was 100° on 9/8.

 

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 this day and on 9/18. This occurred during the strong El Niño of 1982-83.

1963: Northeastward moving Tropical Storm Katherine made landfall in northern Baja California with rainfall of up to 6.50 inches in the mountains from this day to 9/19. 3.86 inches fell in San Bernardino, 3.44 inches in Riverside, 2.66 inches in Victorville and Cuyamaca, 1.90 inches in San Diego, 1.88 inches in Indio, and 1.62 inches in Santa Ana. Disastrous flooding and erosion hit a northern San Bernardino neighborhood

 

1929: A tropical air mass enveloped Southern California. The Meteorologist in Charge at the National Weather Service in San Diego reported temperatures of 111° in the coastal valleys on 9/16. A reading of 94° was observed at San Diego at 4 am on this day.

 

1913: Santa Ana conditions produced a high of 110° at San Diego, which was the all time record high temperature until 9/26/1963 (when it hit 111°). Temperatures reached 111° in Riverside and 110° in Escondido. From San Bernardino came an unofficial and dubious report of 127°. A carpenter working outside died there, and a few small fires occurred, including one downtown that destroyed one house.=========================================================================TROPICAL EAST PACIFIC REPORT:

DISCUSSION AND 48-HOUR OUTLOOK

——————————

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

located near latitude 19.9 North, longitude 110.2 West. Norma is

moving toward the north near 3 mph (6 km/h). The tropical storm

is expected to move toward the north-northwest or northwest

during the next couple days at a slightly faster forward speed. On

the forecast track, the center of Norma will move near or to the

west of the southern Baja California Peninsula on Sunday and Monday.

 

Maximum sustained winds are near 65 mph (100 km/h) with higher

gusts. Weakening is forecast during the next 48 hours.

 

Tropical-storm-force winds extend outward up to 90 miles (150 km)

from the center. The Mexican Navy station in Isla Socorro recently

reported a wind gust of 48 mph (78 km/h).

 

The estimated minimum central pressure is 989 mb (29.21 inches).

 

 

HAZARDS AFFECTING LAND

———————-

RAINFALL: Norma is expected to produce total rainfall accumulations

of 2 to 4 inches over the southern portion of the Mexican state of

Baja California Sur, with isolated maximum amounts up to 8 inches.

These rainfall amounts may produce life-threatening flash floods.

 

WIND: Tropical storm conditions are expected to first reach the

coast within the warning area by Sunday morning. Tropical storm

conditions are possible within the watch area by late Sunday 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 early next week. These swells are likely to cause life-

threatening surf and rip current conditions. Please consult

products from your local weather office.
