...SMALL CRAFT ADVISORY FOR HAZARDOUS SEAS IN EFFECT UNTIL 9 AM
PST THIS MORNING...
...SMALL CRAFT ADVISORY FOR WINDS IN EFFECT FROM MIDNIGHT TONIGHT
TO 7 AM PST SUNDAY...

The National Weather Service in Portland has issued a Small Craft
Advisory for hazardous seas, which is in effect until 9 AM PST
this morning. A Small Craft Advisory for winds has also been
issued. This Small Craft Advisory for winds is in effect from
midnight tonight to 7 AM PST Sunday.

* WINDS...South to southwest wind rising to 15 to 20 kt with gusts
  to 25 kt late this evening through early Sunday morning.

* SEAS...Seas near 8 to 10 ft with a period of 8 to 10 seconds
  will make for steep seas this morning.

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.

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.
