... A series of cold winter storms to impact Southern California this
week...

Several winter storms are poised to impact Southern California this
week with periods of rain and mountain snow... gusty winds and cold
weather.

The first storm will bring light precipitation as early as Monday
morning as it approaches from the north. Rain and mountain snow will
become more widespread during the afternoon and evening with the
cold front. Rainfall is expected to be light to occasionally
moderate with a tenth to a quarter inch west of the mountains.
Upwards of a half inch is expected over the mountains where snow
will fall above 5000 feet. A Winter Weather Advisory is in effect
for the San Bernardino Mountains for 4 to 9 inches of snow. High
wind warnings and wind advisories are in effect for the mountains
and deserts Monday... and a Gale Warning will be in effect over the
coastal waters.

This first storm will move east on Tuesday and the precip will taper
off during the day. A second storm will approach the area Wednesday
afternoon. Moisture will be limited with this second system... and
precipitation amounts are still being determined. However... it will
bring another surge of cold air and gusty northerly winds into the
region Wednesday afternoon through Thursday morning.

A break in the weather follows with dry weather and offshore flow
Thursday afternoon and Friday... but the long range models show the
potential for a third winter storm next Sunday or Monday.
