## 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 1.7 ft of inundation above ground level is
possible in low-lying areas near shorelines and tidal waterways.

* WHERE...Bayshore locations along the San Francisco Bay, San
Pablo Bay, and Monterey Bay.

* WHEN...From 5 PM Friday to 2 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 1.0 ft above normal (6.84 ft MLLW) at 6:55 PM
Friday 8/7, 1.3 ft above normal (7.15 ft MLLW) at 8:00 PM
Saturday 8/8, 1.6 ft above normal (7.44 ft MLLW) at 9:02 PM
Sunday 8/9, 1.7 ft above normal (7.56 ft MLLW) at 10:01 PM
Monday 8/10, 1.6 ft above normal (7.44 ft MLLW) at 10:57 PM
Tuesday 8/11, and 1.3 ft above normal (7.14 ft MLLW) at 11:49 PM
Wednesday 8/12. 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.
