- ...Coastal Flood Advisory in effect from 9 am Sunday to 8 PM PST Monday... The sun...moon and the Earth are coming into proper alignment to encourage the largest tidal cycles of the season which is expected to occur over the next few days. These extreme tides often refereed to as King tides will result in coastal flooding of low lying areas along our coast line and Bay fronts during periods of high tide. The locations that are typically dry during high tide may become submerged due to this extreme tidal cycle. During periods of extreme low tide expect to see tide pools develop along the immediate coast. The National Weather Service in the San Francisco Bay area has issued a coastal Flood Advisory...which is in effect from 9 am Sunday to 8 PM PST Monday.
- Timing...generally speaking...extreme high tides are expected to occur during the mid to late morning hours of December 21st...22nd and 23rd. Extreme low tide will occur during the late afternoon to late evening hours. The exact timing of tides is location dependent so please visit tidesandcurrents.NOAA.Gov/ports/...for more specific tidal information.
- Locations...low lying areas along the immediate coast and Bay front including marshes and sloughs. These locations may include parking lots...coastal trails...sidewalks...underpasses and roadways.
- Impacts...sea water on roadways...parking lots...trails and sidewalks. People visiting beaches may lose entry and exit to coves and narrow beaches. Precautionary/preparedness actions... A coastal Flood Advisory indicates that onshore winds and tides will combine to generate flooding of low areas along the shore. Do not leave your vehicle in low lying parking lots near the coast or Bay front. Do not travel through flooded roadways. If visiting the coast avoid narrow beaches and coves.
