Whatcom County wakes to inches of new snow accumulations

WHATCOM COUNTY, Wash. — A second and more significant snow event this week arrived overnight leaving inches of snow accumulation across Whatcom County.

Law enforcement and tow companies were busy overnight helping stranded drivers, clearing abandoned vehicles and dealing with multiple crashes.

A low-pressure system made landfall in Washington State last night. The associated front is brushing the very southern part of British Columbia giving another round of heavy snow that began Monday evening. Consider postponing non-essential travel until conditions improve. Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow. Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow.
