waterways.

Shoreline Counties.
* WHEN...From 4 PM Thursday July 9, to 4 AM PDT Thursday July 16.
* IMPACTS...High tide 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 1.1 ft above normal (6.9 ft MLLW) at 7:25 PM
7/9, 1.3 ft above normal (7.1 ft MLLW) at 8:17 PM 7/10, 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.
