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

A fast moving cold front will spread rain along the central coast by
midday Friday. The precipitation will move inland over San Luis
Obispo and Santa Barbara counties Friday afternoon... then southeast
across Ventura and Los Angeles counties through Friday evening.
Showers will persist into Saturday morning across the region... with
a chance of residual showers mainly on north facing mountain slopes
by Saturday afternoon and lingering into early Sunday morning. Most
areas are expected to see 3 to 4 hours of 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 Friday night as colder air moves in aloft. Any
thunderstorms would have the potential to bring brief heavy rain and
small hail.

Rainfall amounts from Friday 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 local amounts up
to two inches across northwestern San Luis Obispo County.
Otherwise... rainfall 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 Friday evening
then fall to near 6500 to 7000 feet by late Friday night... and to
6000 to 6500 feet by Saturday morning. Most of the steady
precipitation should be over before the snow levels lower
significantly. Even so... 2 to 4 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... a Winter Weather
Advisory may eventually be needed for the San Gabriel Mountains.

Southwest winds gusting to 35 to 45 mph are also expected over the
mountains of Ventura and Los Angeles counties and in the Antelope
Valley Friday afternoon and Friday night in advance of the front.
Winds will turn northwest over the area by Saturday morning with
gusts 40 to 45 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 Friday night 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.
