...TSUNAMI ADVISORY IS IN EFFECT FOR THE FOLLOWING LOCATIONS, ALL
COASTAL AREAS OF LOS ANGELES...VENTURA...SANTA BARBARA...AND
SAN LUIS OBISPO COUNTIES...

.Synopsis for the southern California coast and Santa Barbara
Channel including the Channel Islands National Marine Sanctuary and
National Park...at 02Z, or 7 PM PDT, a 1025 mb surface high was 800
NM WSW of Point Conception while a 1011 mb surface low was over
southern Nevada. A tsunami capable of producing strong currents that
may be hazardous to swimmers, boats, and coastal structures is
expected. Widespread inundation is NOT expected. However, damage at
the harbors will be possible. Surging water in and out of harbors
can cause boats and docks to detach from structures. Port San Luis
and Morro Bay will be of particular concern for these impacts,
however other locations anywhere in the Advisory area will be
susceptible to impacts including coastal flooding. If you are
located in this coastal area, move off the beach and out of harbors
and marinas. Do not go to the coast to watch the tsunami. Be alert
to instructions from your local emergency officials.
