沿海洪水警报

* 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 south-facing beaches due to the
expected combination of very high level tide levels around 8
feet (including additive effect of low barometric pressure and
onshore winds gusting to 15 to 25 mph), high surf of 5 to 8
feet, and light to moderate rainfall. For all other beaches,
minor to moderate coastal flooding is expected near times of
high tide. From Sunday night through Tuesday, there will be the
continued threat of at least minor to moderate coastal flooding
and elevated surf across Los Angeles county beaches, especially
south facing shores. Dangerous rip currents are likely.

* WHERE...Malibu Coast and Los Angeles County Beaches.

* WHEN...For the Coastal Flood Warning, until 3 PM PDT Sunday.
For the High Surf Advisory, from 6 AM to 10 PM PDT Sunday. For
the Coastal Flood Advisory, from 3 PM Sunday to 2 PM PDT
Tuesday.

* IMPACTS...For vulnerable south-facing beaches (such as Alamitos
Peninsula and Naples in Long Beach as well as Malibu),
SIGNIFICANT sea- water flooding will likely DAMAGE coastal
structures and beach roadways around the time of high tide,
especially the Sunday morning high tide. In addition,
significant ponding of water on low-lying beach roadways could
make driving difficult. THERE IS GROWING CONFIDENCE THAT THE
EXPECTED COASTAL FLOODING IMPACTS ON SUNDAY MORNING FOR
VULNERABLE SOUTH FACING BEACHES OF LA COUNTY COULD BE THE MOST
SIGNIFICANT WE HAVE SEEN SO FAR THIS SEASON, INCLUDING THOSE
SEEN WITH MARIE. For all other beaches and harbors, shallow with
minor to moderate sea- water flooding will likely impact
beaches and walkways, especially with the Sunday morning high
tide which could cause local damage to most vulnerable locations
such as Venice. For all beach areas, significant erosion is
expected. There is an increased risk for ocean drowning.
Dangerous and life- threatening 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 (nearly 2 feet above astronomical high tide of
6.1 feet), returning to around 7.5 feet for Monday and Tuesday
mornings. The projected high tides of around 8 feet for Sunday
morning would approach or exceed recent record tide levels for
LA county. Large secondary high tides are also expected each
evening.
