## extract

Coastal Flood Advisory — San Francisco; North Bay Interior Valleys; San Francisco Bay Shoreline
Severity: Minor. Certainty: Likely.
* 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.
