...small craft advisory for hazardous seas remains in effect
until 3 pm pst friday...

* seas...12 to 17 feet.

precautionary/preparedness actions...

a small craft advisory for hazardous seas means that waves are
expected to be hazardous to small craft. mariners should avoid
shoaling areas. long period swell can sharpen into large breaking
waves in shoaling areas. it is not unusual for waves to break
much farther from shoaling areas than is normally experienced.
remember...breaking waves can easily capsize even larger vessels.
