...SMALL CRAFT ADVISORY FOR HAZARDOUS SEAS IN EFFECT UNTIL 4 PM
PST SATURDAY...
...SMALL CRAFT ADVISORY FOR WINDS IN EFFECT UNTIL 4 AM PST
SATURDAY...

The National Weather Service in Portland has issued a Small Craft
Advisory for winds, which is in effect until 4 AM PST Saturday.
A Small Craft Advisory for hazardous seas is also in effect until
4 PM PST Saturday. 

* WINDS...Southwest 20 to 25 knots with gusts to 30 knots through
  Friday afternoon.

* SEAS...Combined seas near around 25 feet with wave periods
  around 16 seconds, subsiding to 20 feet overnight. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Small Craft Advisory for wind means that wind speeds of 21 to
33 knots are expected. Inexperienced mariners, especially those
operating smaller vessels should avoid navigating in these
conditions.

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.
