## extract

Coastal Flood Advisory — San Francisco; North Bay Interior Valleys; San Francisco Bay Shoreline
Severity: Minor. Certainty: Likely.
* WHAT...Up to 1.8 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 1.7 ft above normal (7.5 ft MLLW) at
10:06 PM 7/12, 1.8 ft above normal (7.6 ft MLLW) at 11:01 PM
7/13, 1.6 ft above normal (7.4 ft MLLW) at 11:55 PM 7/14, 1.3
ft above normal (7.1 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.
