Western Whatcom County could see up to several inches of snow before Monday morning, according to the National Weather Service.
Bellingham and other low-lying areas could get 3 to 5 inches of snow Sunday and Sunday evening, according to a winter storm watch issued by the weather service early Saturday, Feb. 22.
Areas closer to the North Cascades were looking at the possibility of almost a foot of new snow from Saturday through Sunday evening, according to a winter weather advisory the service issued Saturday afternoon.
A light snow fell in Bellingham and surrounding areas well into the day Saturday, but roads remained bare and wet for the most part.
As more snow falls, drivers should be aware that roads could become slippery and snow-packed, NWS meteorologist Johnny Burg said.
Bellingham was expected to have a high of around 30 degrees Sunday, with lows in the mid-20s Sunday night, so some snow could start to stick around, Burg said.
Anything that does stick would likely start melting early Monday afternoon as temperatures rise to the upper 30s, and should be gone by Tuesday when highs reach the 40s, he said.
The winter storm watch and the winter storm advisory were in effect through late Sunday night and early Monday morning, and will be updated regularly as snowfall predictions change, Burg said.
School districts may start to weigh whether school delays or closures are necessary as early as Sunday evening, but most will likely wait until Monday morning to decide.
There was about 1 inch of snowfall at an elevation of 500 feet near Bellingham as of 11:13 a.m. Saturday, according to Bellingham Weather, a Twitter account dedicated to tracking weather and storm conditions.
The weather service also issued a gale watch for northern inland waters, including the San Juan Islands, to remain in effect Sunday afternoon through Sunday evening. Boaters can expect northeast winds of 25 to 35 knots and wind waves 4 to 6 feet high Sunday afternoon and night, with a significantly increased chance of gale force winds of 34 to 47 knots.
