Heavy snow in mountains
Higher elevations of Whatcom County are under a winter storm warning for heavy snowfall from 4 p.m. Monday to 6 a.m. Wednesday. Two to 4 feet of snow is forecast for the next two days above 2,000 feet.
Temperatures will be in the teens, with west-southwest winds to 11 mph.
“Severe winter weather conditions are expected,” the weather service said. “Significant amounts of snow are forecast that will make travel dangerous. Only travel in an emergency. If you must travel, keep an extra flashlight, food and water in your vehicle.”
With such heavy snowfall, mountain passes could close for avalanche control, the weather service said.
For backcountry travelers, the avalanche danger has increased to high at the treeline and above on western slopes of the Cascades in Whatcom County, according to the Northwest Avalanche Center. The avalanche danger remains moderate below the treeline.
