## extract

Coastal Flood Advisory — San Francisco; North Bay Interior Valleys; San Francisco Bay Shoreline
Severity: Minor. Certainty: Likely.
* WHAT...Up to 1.7 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 1.6 ft above normal (7.4 ft MLLW) at 9:11 PM
7/11, 1.7 ft above normal (7.5 ft MLLW) at 10:06 PM 7/12, 1.7 ft
above normal (7.5 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.
