Small Craft for Hazardous Seas Advisory
Statement as of 2:31 AM PDT on May 22, 2013

... Small Craft Advisory for hazardous seas in effect until 5 PM
PDT this afternoon...

The National Weather Service in Seattle has issued a Small Craft
Advisory for hazardous seas... which is in effect until 5 PM PDT
this afternoon.

* Seas/swells... 10 feet at 10 seconds... subsiding to 8 feet at 11
seconds tonight.

Precautionary/preparedness actions...

A Small Craft Advisory for hazardous seas means that waves will
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.
