Pablo Bay, and Monterey Bay.

isolated road closures expected.
ADDITIONAL DETAILS: At the San Francisco tidal gauge, high
tide is expected to be 1.5 ft above normal (7.34 ft MLLW) at
9:02 PM Sunday 8/9, 1.5 ft above normal (7.36 ft MLLW) at
10:01 PM Monday 8/10, 1.6 ft above normal (7.44 ft MLLW) at

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.
