Coastal Flood Advisory issued August 10 at 10:18PM PDT until August 13 at 2:00AM PDT by NWS San Francisco CA

* 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 1.6 ft above normal (7.44 ft MLLW) at 10:57 PM Tuesday 8/11 and 1.4 ft above normal (7.24 ft MLLW) at 11:49 PM Wednesday 8/12.
