Minor Expected Likely

Coastal Flood Advisory

Coastal Flood Advisory issued July 15 at 3:38AM PDT until July 16 at 4:00AM PDT by NWS San Francisco CA
Jul 15, 3:38 AM Jul 16, 4:00 AM
WHAT: Up to 1.5 ft of inundation above ground level is
possible in low-lying areas near shorelines and tidal waterways.

WHERE: Bayshore locations along the San Francisco and San
Pablo Bays.

WHEN: Until 4 AM PDT Thursday.

IMPACTS: Flooding of lots, parks, and roads with only
isolated road closures expected.

ADDITIONAL DETAILS: At the San Francisco tidal gauge, high tide
is expected to be 1.5 ft above normal (7.3 ft MLLW) at 12:48 AM
7/16. These predictions include both astronomical tides and
roughly 3-6 inches of additional water mainly from a combination
of thermal expansion and accumulated sea level rise since the
tidal datum was established (1983-2001). High tide varies up to
90 minutes earlier or later along the Pacific Coast and through
the San Francisco Bay, respectively.
