...SMALL CRAFT ADVISORY FOR HAZARDOUS SEAS NOW IN EFFECT UNTIL NOON PST TODAY...

...SMALL CRAFT ADVISORY FOR WINDS REMAINS IN EFFECT FROM MIDNIGHT TONIGHT TO 7 AM PST SUNDAY...

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.

...PATCHY LIGHT FREEZING RAIN POSSIBLE THIS MORNING...

A front offshore will push increasing rain into the region later this morning. At 3 am, temperatures in many lowland areas were in the upper 20s to lower 30s. Temperatures will rise this morning.

But, there is a chance that temperatures may not warm above freezing before the rain begins. This would result in patchy light freezing rain. Since rainfall will be light, little if any ice accumulation is expected.

Threat of the freezing rain will be 5 am and 8 am for valleys in the Coast Range and Willapa Hills, and from 8 to 10 am for the Willamette Valley and Clark County.

Again, most areas will not see the freezing rain, as will be quite patchy and short-lived.

Threat of patchy freezing rain may last until 1 pm for valleys in the south Washington Cascades, far north Oregon Cascades and Upper Hood River Valley.

Motorist driving about this morning should be prepared for locally icy conditions.
