... Pacific storm system to affect southwestern California this
afternoon through Saturday...

A cold upper level trough of low pressure and surface cold front
will bring periods of Rain... Mountain snow... possible
thunderstorms... and gusty winds to southwestern California this
afternoon through Saturday.

A fast moving cold front will spread rain along the central coast
this afternoon... then spread into Ventura and Los Angeles counties
this evening. Showers will persist into Saturday morning across the
region... with a chance of residual showers mainly on north facing
mountain slopes from Saturday afternoon through early Sunday
morning. Most areas are expected to see 3 to 4 hours of steady rain
with the initial front... then turn showery as the front moves east.
There will also be a slight chance of thunderstorms over San Luis
Obispo and Santa Barbara counties tonight as colder air moves in
aloft. Any thunderstorms would have the potential to bring brief
heavy rain and small hail.

Rainfall amounts from this afternoon through Saturday are generally
expected to range between three quarters of an inch to one and one
half inches along the central coast... with higher amounts across
northwestern San Luis Obispo County. Otherwise rainfall amounts of
one quarter to three quarters of an inch can be expected for most
areas... with local amounts up to one inch in the San Gabriel
Mountains.

Snow levels will start out above 7500 feet through this afternoon
then fall to 6000 to 6500 feet by Saturday morning. Most of the
steady precipitation should be over before the snow levels lower
significantly. Even so... 1 to 3 inches of snow accumulation will be
possible for the San Gabriel Mountains around 7000 feet and
above... with an inch or less between 6000 and 7000 feet. With the
expected snowfall combined with gusty winds... driving conditions in
the mountains could be difficult tonight.

Southwest winds gusting to around 40 mph are also expected over
the mountains of Ventura and Los Angeles counties and in the
Antelope Valley this afternoon and tonight in advance of the front.
Winds will turn northwest over the area by Saturday morning with
gusts around 40 mph possible in the mountains and Antelope Valley.

Residents near the Colby burn area should monitor the latest
National Weather Service forecasts and statements as the potential
for locally heavy downpours tonight could bring the threat of minor
mud and debris flows.

Since this will be the first widespread rain event in quite some
time... roads will be extra slick due to months of oil buildup on
paved surfaces. Motorists are urged to use extra caution in the
rain. In addition... people planning to travel into the mountains
should be prepared for winter weather driving conditions over the
higher elevations.

Listen to NOAA Weather Radio or your local media for the latest
updates on this storm system.
