the West Coast and was analyzed over central and southern
California with a minimum central pressure of 1006 mb (29.71 in of
Hg). A small occluded front extended southeast from the low
pressure center in central California to a triple point. From the
triple point a cold front extended to the southwest into the
Pacific and a warm front extended to the south and east across
southern California. Moisture is streaming onshore ahead of and
along the cold front, which is producing particularly heavy
precipitation across southern California. Precipitation is falling
as rain at low elevations and as mixed precipitation and snow in
the mountains.

The storm system is forecast to remain stationary over central and
southern California through Saturday morning, then gradually move
east into the Intermountain West Saturday night and Sunday.
Significant mountain snows are likely Friday night into Saturday
with major impacts to travel and infrastructure. Downed trees and
power lines are possible. Lower snow levels may bring significant
snowfall to areas where snow is unusual. Strong winds will lead to
blizzard conditions in some mountainous terrain and passes, and
blowing dust is possible in desert areas. Heavy rain may lead to
flooding of some rivers/streams and flood-prone areas. Strong rip
currents and high surf will be hazardous to swimmers and beach
goers. Temperatures will be well below normal over much of the
region with below freezing readings possible in some areas of
Northern California.

The next Storm Summary will be issued by the Weather Prediction
Center at 700 AM PST. Please refer to your local National Weather
Service office for additional information on this event.
