Pebbly Beach, damaging sea-water flooding is likely. For all
other beaches and harbors, minor coastal flooding is expected.
* WHERE...Catalina and Santa Barbara Islands.
* WHEN...Until 3 PM PDT Sunday.
* IMPACTS...For vulnerable south-facing beaches, sea-water
flooding can damage beach roads and structures, especially
around the time of high tide. For all other beaches and harbors,
shallow and minor sea-water flooding can impact beaches and
walkways. For all beach areas, significant erosion is expected.
There is an increased risk of ocean drowning. Rip currents can
pull swimmers and surfers out to sea.
* ADDITIONAL DETAILS...Sunday carries the widest range of coastal
flooding outcomes due to chances of rain, wind, low pressure
tidal enhancements, and swells from multiple directions. Coastal
flooding impacts on Sunday could be similar to other days, or
greatly enhanced. High tides of 7.3 to 7.6 feet will be common
each morning. This warning may be extended past Sunday, or
converted to a Coastal Flood Advisory through Tuesday.
