Autumn may have started on a rather tranquil note but it's sure going out with some fireworks.
Another in a parade of storms over the past several days is set to roll in Monday evening, promising another round of heavy rains, strong winds, and heavy mountain snows for the higher elevations.
Monday morning into the midday hours represent the calm before the storm until the rain and wind arrives later in the afternoon and evening with the passage of a strong cold front.
A High Wind Warning is in effect for the coast from 1 p.m. to 10 p.m. and for the Northwest Interior (Whatcom/Skagit Counties, the Port Townsend area and Whidbey/Camano/San Juan Islands) from 4 p.m. until 10 p.m. for southeasterly winds gusting to 40-60 mph. Those wind speeds are strong enough to potentially cause power outages.
The Olympic Mountains will protect the Puget Sound region from the strongest winds in this setup, but it will still be a windy afternoon and evening with gusts to 25-35 mph.
Up in the mountains, it's another big gob of snow, especially in the northern half of the Cascades above 3,500 feet. A Winter Storm Warning is in effect for the far north Cascades (Mt. Baker area) from 6 p.m. Monday through 6 p.m. Tuesday for as much as 21 inches of new snow along with 45 mph wind.
In the Central Cascades, a Winter Weather Advisory is in effect for the same time above 3,500 feet for 14-17 inches of new snow, primarily Stevens Pass. Snow levels should be just above Snoqualmie Pass but keep an eye on the pass reports just in case it sneaks lower. About 5-10 inches of new snow is also expected around Hurricane Ridge.
As for rainfall, a days-long Flood Warning for the flood-prone Skokomish River remains in effect. Most of the rain for this storm is aiming at southwestern Washington where 3-5 inches could fall, meaning some rivers in southwestern Washington and the Olympic Mountains could reach flood stage later this week.
The stormy pattern continues through the week and into next weekend.
