MONDAY...
...HIGH SURF ADVISORY REMAINS IN EFFECT UNTIL 10 PM PDT MONDAY...
* WHAT...For the Coastal Flood Advisory, minor to moderate
coastal flooding can be expected near times of high tide. For
the High Surf Advisory, large breaking waves of 8 to 12 feet
is expected with dangerous rip currents.
* WHERE...San Luis Obispo County Beaches and Santa Barbara
County Central Coast Beaches.
* WHEN...Until 10 PM PDT Monday.
* IMPACTS...Minor to moderate flooding of sea water is likely
around high tide at beach and harbor areas that is uncommon
with normal tidal ranges. Low lying areas will be most
susceptible, including Oceano. Enhanced beach erosion is
likely. The risk for significant damage is very low. There is
an increased risk of ocean drowning. Rip currents can pull
swimmers and surfers out to sea. Waves can wash people off
beaches and rocks, and capsize small boats nearshore. Large
secondary high tides are also expected each evening.
* ADDITIONAL DETAILS...High tides are expected to be around 7
feet on Monday morning.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
Take the necessary actions to protect flood-prone property. Do
NOT drive around barricades or through water of unknown depth.
Remain out of the water due to dangerous surf conditions, or stay
near occupied lifeguard towers. Rock jetties can be deadly in
such conditions, stay off the rocks.

closed. Do not drive around barricades or through water of
unknown depth. Take the necessary actions to protect flood-prone
property.

AFTERNOON...
* WHAT...A very long period westerly swell will increase the
threat of sneaker waves.
* WHERE...Coastal Del Norte, Northern Coastal Humboldt,
Southwestern Humboldt and Coastal Mendocino Counties.
* WHEN...Through Monday afternoon. The risk will increase as winds

jetties, and beaches. These sneaker waves can also move large
objects such as logs, crushing anyone caught underneath.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
Don`t be fooled by an ocean that looks calm. There can be
30 minutes of small waves before a sneaker wave strikes. Avoid
rocks and jetties. Avoid steep beaches. Stay much farther back
