...SMALL CRAFT ADVISORY FOR WINDS IN EFFECT FROM 2 PM THURSDAY TO
11 PM PDT FRIDAY...
...SMALL CRAFT ADVISORY FOR HAZARDOUS SEAS NOW IN EFFECT FROM
5 PM THURSDAY TO 3 AM PDT FRIDAY...

The National Weather Service in Portland has issued a Small Craft
Advisory for winds, which is in effect from 2 PM Thursday to
11 PM PDT Friday.



* WINDS...North 15 to 20 kt with gusts to 25 kt. Strongest winds
  will be in the afternoon and evening hours.

* SEAS...Become steep and hazardous as seas build to around 7 ft
  with a dominant period of 7 seconds Thursday evening.



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.
