* WHAT...DAMAGING sea-water coastal flooding is likely through
Sunday, especially near the Sunday morning high tide where
anticipated tide levels are expected to be around 8 feet. The
most likely areas for DAMAGING coastal flooding on Sunday
morning will be vulnerable southeast facing beaches, such as
Avalon and Pebbly Beach. For all other beaches and harbors,
minor to moderate coastal flooding is expected. The most
DAMAGING and WIDESPREAD coastal flooding risk along southeast
beaches will likely be with the Sunday morning high tide due to
the expected combination of very high level tide levels
approaching 8 feet (including additive effect of low barometric
pressure, high surf of 5 to 8 feet, and light to moderate
rainfall.
* WHERE...Catalina and Santa Barbara Islands.
* WHEN...For the Coastal Flood Warning, until 3 PM PDT Sunday.
For the Coastal Flood Advisory, from 3 PM Sunday to 2 PM PDT
Tuesday.
* IMPACTS...Sea-water flooding of beach and harbor roads, parking
lots, and walkways is likely, especially around the time of high
tide. Isolated damage is likely across southeast facing beaches
near Sunday mornings high tide. Significant beach erosion is
expected. There is an increased risk for ocean drowning. Rip
currents can pull swimmers and surfers out to sea. Large
breaking waves can cause injury, wash people off beaches and
rocks, and capsize small boats near shore.
* ADDITIONAL DETAILS...High tides of around 8 feet are expected on
Sunday morning, returning to around 7.5 feet for Monday and
Tuesday mornings. Large secondary high tides are also expected
