January typically ranks among the wettest months of the year, and this year is no exception as a significant winter storm system approaches. The most impactful weather, including strong winds, rain, and snow in the mountains, is expected on Tuesday and will gradually ease over the following days, leading into a quieter weekend.
Morning commuters should brace for rain, particularly in Kitsap County and the South Sound region. Between 7 a.m. and 9 a.m., showers will spread towards north Seattle and Bellingham, advancing into Everett and south Whidbey by late morning or midday. Gusty winds from the south and west will accompany the rain, with speeds reaching 30-40 mph in areas like Magnolia and Bellevue. The gusts could exceed 45 mph in northern Whidbey and Burlington, prompting a Wind Advisory for regions including La Push, Clallam Bay, and Lake Crescent, where power outages could occur.
Mountain snow has already begun to fall over the Olympic Mountains, where a Winter Weather Advisory is in effect, predicting 1 to 2 feet of snow and hazardous travel conditions on mountain roads. The snow started a bit later in the Cascades but has already begun accumulating in the highlands of Whatcom and Skagit counties. A Winter Storm Warning remains active for the Cascades, projecting 2 to 4 feet of snow over the next three days, with fluctuating snow levels between 1,500 feet and 3,000 feet.
As the week progresses, temperatures may drop below 1,000 feet by Thursday morning, potentially bringing sleet or slush to the lowlands, particularly in Bellingham and the foothill valleys. Rain will be widespread on Tuesday, transitioning to a more intermittent pattern for the evening commute, and continuing through Wednesday and Thursday. Fortunately, a break in the weather is expected on Friday and Saturday, although showers are likely to return by Sunday, particularly in the mountain passes.
Residents are encouraged to stay informed and prepare for variable weather conditions over the coming days.
