Alert
Details:
* WHAT...Up to 1.6 ft of inundation above ground level is possible in low-lying areas near shorelines and tidal waterways. * WHERE...Bayshore locations along the San Francisco Bay, San Pablo Bay, and Monterey Bay. * WHEN...Until 2 AM PDT Thursday. * 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 1.4 ft above normal (7.25 ft MLLW) at 8:00 PM Saturday 8/8, 1.6 ft above normal (7.44 ft MLLW) at 9:02 PM Sunday 8/9, 1.6 ft above normal (7.46 ft MLLW) at 10:01 PM Monday 8/10, 1.6 ft above normal (7.44 ft MLLW) at 10:57 PM Tuesday 8/11, and 1.3 ft above normal (7.14 ft MLLW) at 11:49 PM Wednesday 8/12. 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. |
