... 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.
