Coastal Flood Advisory issued December 23 at 7:45AM PST until December 24 at 9:00AM PST by NWS Los Angeles/Oxnard CA

* WHAT…Large breaking waves will build this morning, peak at
18 to 25 feet this afternoon into Tuesday morning, then will
subside slowly during Tuesday. Very dangerous rip currents are
expected. For the Coastal Flood Advisory, coastal flooding is
expected.

* WHERE…San Luis Obispo County Beaches and Santa Barbara
County Central Coast Beaches.

* WHEN…For the High Surf Warning, until noon PST Tuesday. For
the Coastal Flood Advisory, until 9 AM PST Tuesday.

* IMPACTS…Flooding of sea water is likely around the times of
high tides, over vulnerable low-lying coastal areas such as
parking lots, beaches, and walkways. Significant damage to
roads or structures is NOT expected. Powerful waves and strong
rip currents will pose an exceptional risk of ocean drowning
and damage to coastal structures like piers and jetties. Large
breaking waves can cause injury, wash people off beaches and
rocks, and capsize small boats near shore.

* ADDITIONAL DETAILS…High tides between 4.0 and 5.0 feet MLLW
are expected each morning between 4 AM and 6 AM. The risk for
shallow but impactful coastal flooding is highest during these
times, with flooded beach roads and parking lots possible,
especially for the Oceano Dunes area. It appears that the risk
of coastal flooding will be greatest tonight through Tuesday
morning.
