A special statement issued by the Weather Service says an approaching Pacific storm has the potential to produce damaging winds on the coast Sunday night and in the interior north of Everett early Monday.
The Grays Harbor County Department of Emergency Management issued its own warning for the same period, advising coastal residents of heavy rain and possible 30-foot coastal swells on the beaches.
Elsewhere in Western Washington it will also become windy with gusts to 50 mph possible Sunday night through Monday morning. A period of wet snow is also possible in the lowlands around the Hood Canal.
Gale force winds are expected over the inland waters of the Puget Sound and Strait of Juan de Fuca.
The mountains could receive another 1 to 3 feet of snow by late in the day Monday from the incoming system - on top of the 10 to 16 inches being predicted from Saturday through midday Sunday.
It will also be very windy in the mountains, with extremely low visibility at times due to blowing and drifting snow. Westerly winds in the passes behind the low on Monday could easily exceed 40 mph with higher gusts, according to National Weather Service meteorologists.
A colder air mass will follow the storm Monday night, with snow levels predicted to plummet to near sea level by Tuesday morning. High temperatures on Tuesday may struggle out of the 30s, including the Puget Sound region.
