Coastal Flood Advisory issued October 29 at 4:23AM PDT until October 31 at 6:00PM PDT by NWS San Francisco CA
WHAT: Up to 1.9 ft 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 6 PM PDT Saturday.
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
01:43 PM Thursday 10/29, 1.6 ft above normal (7.4 ft MLLW) at
02:39 PM Friday 10/30, and 1.1 feet above normal (6.9 ft MLLW)
at 03:44 PM on Saturday 10/31. 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.
