Update to

High Surf Advisory issued January 14 at 3:36AM PST expiring January 18 at 6:00AM PST by NWS Los Angeles/Oxnard CA

Alert

A few strong storm systems in the Gulf of Alaska have caused a
large northwest long period swell. These large long period swells
will bring an extended period of high surf to northwest and west
facing beaches across SW California beaches beginning Monday and
persisting through at least Wednesday night. Another larger swell
is expected to move into the coastal waters once again late this
week into next weekend.
The National Weather Service in Los Angeles/Oxnard has issued a
High Surf Advisory, which is in effect from 10 AM Monday to 6 AM
PST Thursday. The Beach Hazards Statement has been cancelled.

* SURF AND TIMING... Energy from a large NW swell across the
outer waters will filter into the Southern California Bight by
mid morning Monday affecting unexposed west to northwest facing
beaches across Ventura and Los Angeles Counties through late
Wednesday night into very early Thursday morning. Initially,
High surf between 6 to 9 feet can be expected, then increase to
between 7 to 10 feet with local sets to 12 feet Monday night
through early Wednesday. High surf will begin to diminish some
through late Wednesay night.

* IMPACTS... Large, powerful, and dangerous waves with strong
currents will create an increased risk in drownings. Sneaker
waves can suddenly wash over previously dry beaches and jetties.
There will be also a high risk of life-threatening rip
currents. Local flooding of low lying beach parking lots will be
possible with the high surf.

Instructions

A High Surf Advisory means that high surf will affect beaches in
the advisory area...producing localized beach erosion and
dangerous swimming conditions. Swim near a lifeguard. If caught
in a rip current, relax and float. Don't swim against the
current. If able, swim in a direction following the shoreline. If
unable to escape, face the shore and call or wave for help.
