possible in low-lying areas near shorelines and tidal
waterways.
* WHERE...Bay Shoreline locations of San Pablo Bay, San
Francisco Bay, and Monterey Bay.
* WHEN...Until 6 PM PDT Sunday.
* 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. More substantial impacts are expected along bayshore
Marin County where increased flooding is anticipated across
low lying areas.
* ADDITIONAL DETAILS...At the San Francisco tidal gauge, high tide
is expected to be 1.9 ft above normal (7.7 ft MLLW) at 02:39 PM
Friday 10/30, 1.5 feet above normal (7.3 ft MLLW) at 03:44 PM on
Saturday 10/31, and 1.0 ft above normal (6.8 ft MLLW) on Sunday
11/01 at 3:59 PM. 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.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
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.
