## extract

Coastal Flood Advisory — Coastal North Bay Including Point Reyes National Seashore; San Francisco Peninsula Coast; Northern Monterey Bay; Southern Monterey Bay and Big Sur Coast
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...Pacific Coast including Monterey Bay.

* WHEN...Until 4 AM PDT Wednesday.

* 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. 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.
