* WHEN...From 8 AM Saturday to 3 PM PDT Thursday.

Rising tides will bring water and waves farther up the beach

is expected to be 1.1 ft above normal (6.9 ft MLLW) at 10:39 AM

Wednesday 10/28, and 1.7 ft above normal (7.5 ft MLLW) at 01:43
PM Thursday 10/29. These predictions include up to 1.0 ft of

threat. High tide varies up to 90 minutes earlier or later along
the Pacific Coast and through the San Francisco Bay,
respectively.
