...A VERY LARGE SWELL TRAIN WILL BRING COASTAL HAZARDS TO WEST TO
NORTHWEST FACING BEACHES...

A strong storm has been impacting the area and will continue to
significantly increase wave energy into early Tuesday. This wave
energy will transition through the coastal waters and peak this
afternoon. Swell of 16 to 24 feet at 16 to 18 seconds is forecast
to arrive with the swell train as it peaks on Monday and result
in a number of coastal hazards. These hazards include large
breaking waves of 20 to 30 feet (higher at favored break points),
increased risk of strong longshore and rip currents, increased
risk of coastal erosion and minor coastal flooding, and enhanced
coastal run up concerns due to the summer beach profiles in place.
Due to the early arrival of these large waves, many beaches are
still transitioning from their summer beach profiles and lack the
features and steepness to resist larger wave run up on coasts.
This means that more of this wave energy will have a chance to
move onto the beach and overtake individuals, potentially injuring
them, or pulling them into the cold ocean. Each year, people die
at the coast due to these or similar ocean conditions. A high surf
warning for the entire coast has been issued for this threat and
is in effect from 11PM Sunday to 11AM Tuesday, with the highest
risks once again at west to northwest facing beaches.

...HIGH SURF WARNING REMAINS IN EFFECT UNTIL 11 AM PDT TUESDAY...

* WHAT...For the High Surf Warning, dangerously large breaking
waves of 20 to 30 feet, greatly increased coastal run up, strong
rip currents and longshore currents, and increased risk of
minor coastal flooding in low lying areas.

* WHERE...Coastal North Bay Including Point Reyes National
Seashore, Southern Monterey Bay and Big Sur Coast, San
Francisco Peninsula Coast, San Francisco and Northern Monterey
Bay.

* WHEN...Until 11 AM PDT Tuesday.

* IMPACTS...Breaking waves can sweep people off jetties and
docks, and into dangerous seas. Life-threatening swimming
conditions and significant beach erosion can be expected.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Everyone should remain out of the water due to life-threatening
surf conditions. Stay off of jetties, piers, and other waterside
infrastructure.

...SMALL CRAFT ADVISORY REMAINS IN EFFECT UNTIL 9 PM PDT THIS
EVENING...

* WHAT...West winds 5 to 15 kt with gusts up to 25 kt and seas
10 to 12 feet at 17 seconds.

* WHERE...Monterey Bay.

* WHEN...Until 9 PM PDT this evening.
