SEATTLE – A strong storm will continue to affect Western Washington through Monday, with heavy rain and gusty winds.
A coastal flood warning is in effect for the central Washington coast until 5 a.m. Tuesday.
The National Weather Service says high surf is expected along the central Washington coast through Monday night.
The Weather Service says waves along the coast were up to 23 feet on Sunday afternoon. Waves will continue building slowly Sunday night, then peak between 29 and 34 feet Monday morning.
On the Washington coast, a cabin that had been teetering on the edge fell into the Pacific early Sunday.
Anyone venturing onto the beaches should be extremely careful and stay back from the water's edge. The Weather Service says waves this large will sweep up the beaches faster than people can run, and the waves will likely throw around large objects and debris.
The rain is expected to continue across Western Washington. The National Weather Service has issued a flood warning for the Skokomish River near Potlatch.
On Sunday morning, sustained winds reached 35-40 mph on the coast, with peak gusts to 62 mph. Peak winds on Monday will hit the interior in the morning, with sustained southerly winds of 20-30 mph near Puget Sound.
As the cold front associated with the low crosses the area, temperatures will drop and snow levels will plummet to 4000 feet.
A winter storm warning has been issued for the north and central Cascades for heavy snow above 4000 feet through Monday. Travelers over the Cascades should expect winter conditions Sunday afternoon through the day Monday.
The National Weather Service says roads to Paradise and Sunrise in Mount Rainier National Park will likely receive 6 inches to a foot of snow through Monday afternoon.
KING 5 forecaster Lisa Van Cise says showers will continue Tuesday, especially over the coast and Cascades.
"Wednesday will be a dry day after a few early morning showers. Enjoy that dry weather Wednesday, because another wet system moves in Thursday," she said.
White-out conditions at Mount Hood
By mid-day Sunday, snow was accumulating at both Timberline Lodge and Mount Hood Meadows. The Meadows website reported white out conditions and five inches of snow. Timberline reported eight inches at the lodge.
At Government Camp, the temperature at 3:30 was 31 degrees and snow was just beginning to fall.
"At 5,000 feet and above, it's an all-out snowstorm," said KGW meteorologist Rod Hill.
In the Willamette Valley and Portland area, expect the rain showers to continue on into Tuesday morning, said Hill. Temperatures should remain between the mid 40s overnight to mid 50s during the day.
The Coast Guard has closed the Columbia River and Tillamook Bay bars and the Siuslaw River mouth at Florence, Ore. because of hazardous storm conditions.
"A high surf warning means that dangerously high surf will batter beaches in the advisory area producing deadly rip currents and minor beach erosion," officials said. "This is not a time to be near the water."
