the national weather service in san francisco has issued a high
surf advisory, which is in effect until 9 pm pdt wednesday. 

* waves and surf...seas building rapidly from 14 to 16 feet with
  breaking waves to 20 feet possible in the surf zone.

* timing...3 pm tuesday through 9 pm wednesday.

* impacts...beach visitors, surfers, fisherman and others visiting
  the beaches should be prepared for rapidly building seas with
  dangerous crashing waves in the surf zone. sea surface
  temperatures in the mid 50s will cause hypothermia in a short
  amount of time. the surf zone has been relatively tranquil and
  this will be a quick change in surf conditions. beach and water
  related fatalities are common but preventable. dont become a
  statistic. 

precautionary/preparedness actions...

a high surf advisory means that high surf will affect beaches in
the advisory area, producing rip currents, localized beach
erosion and sneaker waves.
