* surf... surf will continue at 8 to 12 feet through tonight. The
high surf will likely diminish some on Sunday morning, before
increasing once again late Sunday afternoon and evening. Very
large and potentially damaging surf will be likely late Sunday
evening through early Tuesday morning, likely peaking late
Sunday night through Monday. Breakers between 18 and 25 feet
will be common across west and northwest facing beaches, with
local sets up to 30 feet possible during this time period.

* Coastal flooding... minor coastal flooding of low-lying areas
will be likely during times of high tide on Monday and Tuesday
mornings when peak tides around 5.5 feet are expected between
530 and 630 am each morning. Water could spill into normally
dry beaches, beach parking lots and Harbor walkways.

* Impacts... the high surf will continue to bring a threat of
strong rip currents and breaking waves that can suddenly
overtop rocks and jetties. From late Sunday evening through
early Tuesday morning, there will be more significant and
numerous impacts with the very large and damaging surf
expected, including frequent and very strong rip currents and
sneaker waves, along with a threat of significant beach
erosion and possible damage to piers and coastal structures.
The very large surf and very strong rip currents will bring
extremely dangerous and potentially life-threatening
conditions to unexperienced swimmers and surfers, with
powerful waves battering rocks and jetties. In addition, large
breaking waves can be expected across the Morro Bay Harbor
entrance, potentially capsizing small boats.

* Tides... peak high tide on Monday will be 5.4 feet around 550
am, then 5.7 feet around 620 am Tuesday morning.

Precautionary/preparedness actions...

A high surf advisory means that high surf will affect beaches in
the advisory area... producing localized beach erosion and
dangerous swimming conditions.

A high surf warning indicates that dangerous... battering waves
are expected to pound the shoreline, bringing potentially
damaging and life- threatening conditions. It is advised that
people remain away from the shoreline from Sunday night through
Tuesday, especially staying off rocks and jetties. If caught in a
rip current, relax and float. Don't swim against the current. If
able, swim in a direction following the shoreline. If unable to
escape, face the shore and call or wave for help.

A coastal flood advisory indicates that onshore winds and tides
will combine to generate flooding of low areas along the shore.
