National Preparedness Level 5 

Southern California Area

Preparedness Level: (PL 3) 

Northern California Area

Preparedness Level (PL 4) SYNOP: A trough moving through the Pacific Northwest will produce cooler, breezier weather across much of the area today. Highs should be 5-10 degrees cooler than yesterday with widespread stratus along the central coast and interior valleys which will slowly clear during the afternoon. Temperatures this afternoon will only be in the 60s to lower 70s along the coast to the upper 70s to lower 80s in the valleys. West winds of 20-30 mph will be possible in the Kern County Mountains, Antelope Valley, Banning Pass and the east side of the Cleveland National Forest. Northwest winds of 15-25 mph will occur Friday in these same areas as well as the central coast. Local north winds of 10-20 mph will be possible across the Santa Ynez Range tonight and again Friday night. Isolated showers and thunderstorms will be possible today along the Sierra Crest, but today should be the last day of convection across the district. This weekend, temperatures will warm slightly and winds should become light. Early next week, an unseasonably deep trough will bring much cooler weather and gusty winds to the Sierras into Inyo and Mono Counties. West winds gusts over 50 mph may occur Monday into Tuesday morning across the Sierra high country eastward into the Owens Valley and Inyo National Forest. Expect widespread west winds of 20-30 mph over the deserts early next week as well. Light showers may be possible in these same areas Tuesday, but most of the precipitation should remain north of the area. Temperatures will drop to well below normal readings with highs only in the 50s in the mountains to the 70s in the valleys next Tuesday and Wednesday. There is a possibility of light offshore winds developing over Southern California late next week. Temperatures should warm back to near normal by next Thursday or Friday FLASH FLOOD POTENTIAL INDEX FOR EXTREME SOUTHWESTERN CALIFORNIA

Scattered showers and storms remain possible across  much of the region this morning before a strong trough pushes  moisture eastward tonight. Shower activity to be focused mainly  across Lincoln County on Friday with dry conditions area wide this  weekend. The weather will be cooler than recently experienced over  the weekend with temperatures several degrees below normal.

 

SPECIAL NOTES:

 

SANTA ANA OUTLOOK   September and the September through November

Summary:

The PDO and the Niño3.4 Index lack a strong signal which is causing these predictors to be less influential in the forecast

process. Analog methods using these indices show near to below normal Santa Ana wind days through November.

However, global sea surface temperature anomaly trends suggest above normal number of Santa Ana wind days for this

fall. Based on all current model guidance, there is likely to be a near normal number of Santa Ana wind days across Southern California for both the September and the September through November time periods. Confidence in this forecast is moderate.

 

Fire Potential:

Moisture content among the native vegetation is reaching its lowest level of the year. Live fuel moisture among Chamise

is primarily in the 60s while the dead fuel moisture is currently at record low levels. Unless significant wetting rains

occur, fuels should remain highly receptive to ignitions through at least the end of October, if not longer. Any offshore

winds that do occur this fall will be problematic due to the abundance of grass that has resulted from last winter’s heavy

rains. As a result, large fire potential for much of Southern California will be above normal this fall.

 

DAILY FUELS/FIRE POTENTIAL:

Large fire potential may become elevated in some of the desert interface regions such as the Kern County Mountains, “Canyon Country” of northern Los Angeles County and through the Banning Pass. Gusty winds will allow for wind-driven fire behavior during the afternoon hours today and Friday. But fine fuel moisture conditions have rebounded during the last 7-10 days due to humid weather and spotty precipitation and ignition components have moderated somewhat. Next week, the highest fire potential may shift northward to the east side of the Sierra Crest into the Owens Valley where downsloping winds may allow for lower RH during the afternoon Monday. Cool temperatures and cloudy skies may hinder fire potential in this area, but very gusty and erratic winds would allow for very rapid rates of spread even though fuel temperatures may be low. Late next week, the first offshore winds of the season due northeast and easterly pressure gradients may occur, resulting in lowering RH over Southern CA. Expect light IA and resource demand through the period. A widespread precipitation event over the Pacific NW and northern Rockies may allow for much lower national resource demand in coming days.’

2011: A rather large and intimidating funnel cloud was observed near Warner Springs. Ultimately, the funnel never made contact with the ground and was uneventful outside of its appearance.

 

1997: Large swell produced by Hurricane Linda slammed into Orange County. Surf as high as 18 feet was reported at the Wedge in Newport Beach. Five people were swept off a jetty there and were carried 300 yards out to sea before they were rescued by a passing boat. All of the 5 were injured, with one left in critical condition after nearly drowning. =========================================================================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

Depression Fifteen-E, located several hundred miles southwest

of the southern tip of the Baja California peninsula, and on

recently upgraded Tropical Storm Max, located near the southwest

coast of Mexico.

 

A broad area of low pressure is located several hundred miles south

of the southern tip of the Baja California peninsula. Shower

activity continues to show signs of organization, and a tropical

depression is expected to form within the next couple of days while

the system moves slowly northwestward. For more information on

this system, please see High Seas Forecasts issued by the National

Weather Service.

* Formation chance through 48 hours…high…80 percent.

* Formation chance through 5 days…high…90 percent.

 

An area of low pressure located about 1500 miles east-southeast of

the Hawaiian Islands is producing persistent shower and thunderstorm

activity. Satellite imagery indicates that a well-defined center

does not currently exist and additional development, if any, is

expected to be slow to occur while this system moves little during

the next several days.

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

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