Minor Expected Likely

Coastal Flood Advisory

Coastal Flood Advisory issued October 25 at 8:36PM PDT until October 29 at 3:00PM PDT by NWS San Francisco CA
Oct 25, 8:36 PM → Oct 29, 3:00 PM
WHAT: Up to 1.9ft of inundation above ground level is
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 3 PM PDT Thursday.

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.

ADDITIONAL DETAILS: At the San Francisco tidal gauge, high tide
is expected to be 1.6 ft above normal (7.4 ft MLLW) at 11:39 AM
Monday 10/26, 1.8 ft above normal (7.6 ft MLLW) at 12:15 PM
Tuesday 10/27, 1.9 ft above normal (7.7 ft MLLW) at 12:56 PM
Wednesday 10/28, and 1.7 ft above normal (7.5 ft MLLW) at 01:43
PM Thursday 10/29. These predictions include up to 1.0 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.
