SEATTLE – The Thanksgiving weekend may seem to end on a rather quiet note, but a storm announces it as a confrontation to reality as we return to work and to school.
Heavy rains, strong winds and freezing rain in the mountains are waiting for you from Sunday night to Tuesday.
The storm was approaching the coast Sunday afternoon and rain is expected to rain in the Puget Sound area during the evening. It will rain and blow until Sunday night.
This system is a bit warmer than the one that brought abundant snow in the mountains during Thanksgiving, with snow levels up to about 7,000 feet. But with the cold air trapped in the passes, the rain ice is ideal, because this rain falls in the cold air near the roads and freezes on the surface. A winter weather report is in effect from 19h. Monday to midday Monday above 2500 feet. Ice accumulations should be less than 1/4 inch.
On the coast and to the north, strong winds are possible when the warm front moves inland. A HIGH WIND WARNING is in effect from midnight Monday morning to Monday evening for the coast and northwestern interior (Whatcom / Skagit Counties, Port Townsend / Admiralty Inlet area and the San Juan Islands , Whidbey and Camano) 40 mph with gusts to 60 mph. The peak of wind would be from Monday morning to Monday afternoon.
The Seattle / Puget Sound area should not receive so many winds thanks to its protection of the Olympic Mountains, with gusts ranging from 25 to 40 mph.
And do not forget the rain. This storm took advantage of the tropical humidity and is expected to bring up to 10 inches of rain in the Olympic Mountains and about 5 to 7.5 inches in the North Cascades. Flood monitoring is in effect for rivers in Mason County (Skokomish River) and Whatcom. The other rivers of the Olympic Mountains and the North Cascades will also be very busy. About 1 inch of rain is expected in the lowlands around Seattle, although the Olympic Rain Shadow will keep the north and northeast of the Olympic Peninsula relatively dry.
The weather will calm down on Tuesday.
