Coastal Flood Advisory

Coastal Flood Advisory issued October 8 at 9:45PM PDT until October 13 at 3:00PM PDT by NWS San Francisco CA
Oct 9, 9:00 AM → Oct 13, 3:00 PM
WHAT: Up to 1.4 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
Monterey Bays.

WHEN: From 9 AM Friday to 3 PM PDT Tuesday.

IMPACTS: Flooding of lots, parks, and roads with only
isolated road closures expected. High tides will result in
flooding along coastal trails, cut off access to some low-
lying beaches and coastal areas, and bring water and waves
farther up the beach than typical.

ADDITIONAL DETAILS: At the San Francisco tidal gauge, high tide
is expected to be 1.2 ft above normal (7.1 ft MLLW) at 11:22 AM
Friday 10/9, 1.4 ft above normal (7.3 ft MLLW) at 11:50 AM
Saturday 10/10, 1.3 ft above normal (7.2 ft MLLW) at 12:18 PM
Sunday 10/11, 1.2 ft above normal (7.1 ft MLLW) at 12:46 PM
Monday 10/12, and 1.1 ft above normal (7.0 ft MLLW) at 1:14 PM
Tuesday 10/13. 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.
