Small Craft Advisory issued July 12 at 8:01PM PDT until July 13 at 9:00AM PDT by NWS San Francisco CA
* WHAT...Northwest winds 15 to 20 kt. * WHERE...Waters from Point Reyes to Pigeon Point 10-60 NM. * WHEN...Until 9 AM PDT Monday. * IMPACTS...Conditions will be hazardous to small craft.
Inexperienced mariners, especially those operating smaller vessels, should avoid navigating in hazardous conditions.
Coastal Flood Advisory issued July 12 at 9:03PM PDT until July 16 at 4:00AM PDT by NWS San Francisco CA
* WHAT...Up to 1.8 ft of inundation above ground level is possible in low-lying areas near shorelines and tidal waterways. * WHERE...Bayshore locations along the San Francisco and San Pablo Bays. * WHEN...Until 4 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 1.7 ft above normal (7.5 ft MLLW) at 10:06 PM 7/12, 1.8 ft above normal (7.6 ft MLLW) at 11:01 PM 7/13, 1.6 ft above normal (7.4 ft MLLW) at 11:55 PM 7/14, 1.3 ft above normal (7.1 ft MLLW) at 12:48 AM 7/16. 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.
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.
