The Bay Area will experience a King Tide in February-- extreme high tide events that happen twice a year. King Tides this year occur on January 19 and 20 and on February 16,17 & 18.
These high tide events can provide a preview of potential impacts to shoreline areas caused by sea level rise in the Bay. Current projections indicate that sea level could rise as much as 16 inches in the next few decades.
Several groups in the Bay Area are collecting photos of high tides around the Bay and coastal areas -- check out http://www.sfbaynerr.org/ctp/KingTides/ for more information, and see the collected photos at http://www.flickr.com/groups/bayareakingtides/
