## extract

Coastal Flood Advisory — San Francisco; North Bay Interior Valleys; San Francisco Bay Shoreline; Northern Monterey Bay; Southern Monterey Bay and Big Sur Coast
Severity: Minor. Certainty: Likely.
* 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 Francisco Bay, Monterey
Bay and Big Sur Coast.

* WHEN...From 8 AM Saturday to 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 1.1 ft above normal (6.9 ft MLLW) at 10:39 AM
Saturday 10/24, 1.4 ft above normal (7.2 ft MLLW) at 11:07 AM
Sunday 10/25, 1.7 ft above normal (7.5 ft MLLW) at 11:39 AM

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.
