Beach Hazard Statement
Issued: 1:34 AM PST Jan. 18, 2017 – National Weather Service

... Beach hazards statement remains in effect from late tonight
through Monday evening...

* hazards... a large long period west to northwest swell will bring
high surf to area beaches late tonight through Monday... with
much larger... damaging surf likely late Friday through Saturday.
Surf of 10 to 15 feet Thursday and Friday may build to 20 to 30
feet late Friday and Saturday... potentially the highest surf
event seen in recent years. The surf will begin to subside
Sunday into Monday... but is expected to remain above high surf

* Impacts... large... powerful and potentially damaging surf will
create dangerous ocean conditions. Coastal erosion will be
likely with potential coastal flooding and damage to coastal
structures such as piers. Frequent strong rip currents and long-shore
currents are expected. Much larger waves may occur without
warning... which can wash people off their feet in the surf zone
or off of rocks and jetties. West-facing Harbor entrances such
as morro Harbor may see breaking waves across the entrance.

Precautionary/preparedness actions...

A high surf outlook is issued when high surf is expected to
affect beaches in the advisory area... producing rip currents and
the potential for beach erosion.

If you do not have to be in the water... stay on the shore. Stay
off rocks and jetties and away from the Waters Edge to avoid
being swept away by larger waves... which may occur without
warning. Never turn your back to the ocean.
