* WHAT...Up to 2.1 ft of inundation above ground level is
possible in low-lying areas near shorelines and tidal
waterways.

* WHERE...Pacific Coast.

* WHEN...Until 5 PM PDT Friday.

* IMPACTS...High tides will result in flooding of low-lying
infrastructure, isolated road closures, and coastal erosion.
Rising tides will bring water and waves farther up the beach
than normal, restricting escape from beaches and coastal areas.

is expected to be 2.1 ft above normal (7.9 ft MLLW) at 12:15 PM
Tuesday 10/27, 1.9 ft above normal (7.7 ft MLLW) at 12:56 PM

Thursday 10/29, and 1.6 ft above normal (7.4 ft MLLW) at 02:39
PM Friday 10/30. These predictions include up to 1.2 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
