Details: 
...COASTAL FLOOD ADVISORY REMAINS IN EFFECT UNTIL 4 PM PDT WEDNESDAY...

* WHAT...Up to 1.4 ft of inundation above ground level is
possible in low-lying areas near shorelines and tidal
waterways.

* WHERE...Bayshore locations along the San Pablo Bay.

* WHEN...Until 4 PM PDT Wednesday.

* IMPACTS...Flooding of lots, parks, and roads with only
isolated road closures expected. High tides will result in
flooding along coastal trails, cut off access to some low-
lying beaches and coastal areas, and bring water and waves
farther up the beach than typical. Dangerous conditions are
forecast along the shoreline. Hazards include sneaker waves,
strong rip currents, and large breaking waves.

* ADDITIONAL DETAILS...At the San Francisco tidal gauge, high tide
is expected to be 1.4 ft above normal (7.2 ft MLLW) at 1:14 PM
Tuesday 10/13, and 1.0 ft above normal (6.8 ft MLLW) at 1:46 PM
Wednesday 10/14. These predictions include up to 1.5 ft of surge
that will enhance the astronomical tide and flooding threat.
High tide varies up to 90 minutes earlier or later along the
Pacific Coast and through the San Francisco Bay, respectively.

Information: 
If travel is required, allow extra time as some roads may be
closed. Do not drive around barricades or through water of
unknown depth. Take the necessary actions to protect flood-prone
property.
