The High Wind Warning is now in effect until 3 am PST Wednesday.

* Timing: winds will strengthen through the morning and peak in
the afternoon.

* Winds: northwest to north winds 30 to 40 mph with local gusts to
60 mph will be likely. The strongest winds are expected below
passes and canyons.

* Impacts: the gusty winds will make travel difficult for high
profile vehicles.

Precautionary/preparedness actions...

A High Wind Warning means a hazardous high wind event is expected
or occurring. Sustained wind speeds of at least 40 mph or gusts
of 58 mph or more can lead to property damage.

... Periods of strong north winds will persist through early
Wednesday...

... Sub-freezing temperatures possible tonight...

Isolated light snow showers with snow levels around 3000 feet over
the north slopes bordering Kern County will persist through the
afternoon. Less than two inches of new snow is possible through the
afternoon.

In the wake of a cold front... periods of strong north and northwest
winds will persist with potentially damaging gusts between 60 and 70
mph across the mountains... Antelope Valley... Santa Barbara South
Coast... Santa Clarita valley... and San Fernando Valley through early
Wednesday morning. High wind warnings are in effect for these areas.
Over the lower elevations wind advisories will remain in effect with
gusts between 35 and 50 mph.

Cold air will settle over the area and under clear skies
sub-freezing temperatures are likely in wind sheltered areas
tonight. Temperatures in the lower to mid 20s will likely occur in
areas of the Antelope Valley... Cuyama Valley... and interior valleys
of San Luis Obispo County... but these areas have already experienced
two hard freezes this season. Otherwise temperatures in the upper
20s to lower 30s will likely occur in the coastal valleys and frost
advisories are likely tonight.

Residents of Southern California are urged to stay tuned to the
latest National Weather Service forecasts for this developing
weather situation.

... Strong winds likely for the Southland today...

... Sub-freezing temperatures possible across portions of the
   Southland tonight...

A cold front passed over the area overnight and brought with
scattered shower activity. Shower activity will continue over the
San Gabriel valley this morning and over the north slopes through
the afternoon. Snow levels will be as low as 3000 feet. A few inches
of new snow will be possible across the north facing slopes... with
accumulating snow possible along Interstate 5 near the Grapevine.

In the wake of the front... strong and widespread northwest winds
are expected across the region today and this evening. This system
could produce damaging wind gusts between 60 and 70 mph across the
mountains... Antelope Valley... Santa Barbara South Coast... Santa
Clarita valley... and San Fernando Valley. High wind warnings are in
effect for these areas. The rest of the Southland are covered by
wind advisories... for wind gusts between 35 and 50 mph.

The influx of much colder air into the region tonight will also
bring the risk of sub-freezing temperatures to wind sheltered
portions of southern and central California. Portions of the Antelope
Valley... Cuyama Valley... and interior valleys of San Luis Obispo
County are expected to have minimum temperatures fall into the lower
to mid 20s... but these areas have already experienced two hard
freezes this season. Other wind protected locations will likely have
minimum temperatures fall into the upper 20s to lower 30s... with
frost advisories possibly being issued.

Residents of Southern California are urged to stay tuned to the
latest National Weather Service forecasts for this developing
weather situation.
