Coastal Flood Advisory

* 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...From 8 PM Saturday to 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.
