...SMALL CRAFT ADVISORY FOR HAZARDOUS SEAS REMAINS IN EFFECT FROM
4 AM TO 10 PM PST THURSDAY...

* WINDS...Northwest 20 to 25 kt with gusts up to 30 kt through
  tonight. Occasional gusts up to 35 kt today.

* SEAS...11 to 14 feet, except peaking 14 to 17 feet this
  afternoon and evening. Seas subsiding to near 10 feet Thursday
  night.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Small Craft Advisory means that wind speeds of 21 to 33 knots
are expected to produce hazardous wave conditions to small craft.
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.

The National Weather Service in Medford has issued a Small Craft

this morning to 10 AM PST Thursday.

* Winds...Northwest 15 to 25 KT. Winds will become north late
  Wednesday night, then diminish to 10 to 20 KT Thursday.

  ft Wednesday, peak at 12 to 15 feet Wednesday night into

  be a combination of short period wind-driven waves, fresh

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Hazardous Seas Warning means very steep and hazardous sea
conditions are imminent or occurring. Recreational boaters should
remain in port, or take shelter until waves subside.  Commercial
vessels should prepare for rough seas and consider remaining in
port or taking shelter in port until hazardous seas subside.

A Small Craft Advisory for hazardous seas means that waves will
be steep enough to create a potential hazard to smaller vessels
and inexperienced mariners.
