Details: 
...COASTAL FLOOD ADVISORY REMAINS IN EFFECT UNTIL 4 AM PDT WEDNESDAY...

* WHAT...Up to 1.7 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 1.6 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. 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.

Information: 
If travel is required, allow extra time as some roads may be
closed. Do not drive around barricades or through water of
unknown depth. Take the necessary actions to protect flood-prone
property.
