Details:
...HIGH SURF WARNING REMAINS IN EFFECT UNTIL 5 PM PST FRIDAY...
...COASTAL FLOOD ADVISORY ALLOWED TO EXPIRE AT 9 AM PST THIS
MORNING...
* WAVES AND SURF...Breaking waves rapidly building to 25 to 35
feet, with favored locations occasionally exceeding 45 feet.
* TIMING...Energetic waves will continue to build this morning,
peaking during the day before gradually subsiding on Friday.
* IMPACTS...Large breaking waves along the coast will lead to
increased wave run-up on beaches with waves topping and
washing over large rocks and jetties. They can easily move
large logs and other beach debris and cause localized beach
erosion. Use extreme caution near the surf zone as these large
waves will be capable of sweeping people into the frigid and
turbulent ocean water. Cold water shock may cause cardiac
arrest, and it also can cause an involuntary gasp reflex
causing drowning, even for a good swimmer. The surf zone will
be very dangerous due to strong currents and powerful breaking
waves.

Information:
A High Surf Warning indicates that dangerous, battering waves are
expected to pound the shoreline, bringing potentially damaging
and life-threatening conditions. It is advised that people remain
away from the shoreline during this event, especially staying off
rocks, jetties and beaches.
