SPOKANE, Wash. (AP) — Heavy snowfall is snarling traffic and producing motor vehicle accidents throughout the Spokane region.

Spokane city officials on Wednesday announced they will undertake a full-city plow.

That means crews will be working 24 hours a day and seven days a week until nearly 5,000 miles of city streets are plowed.

City officials say more than 90 pieces of equipment are working to improve road conditions.

The storm follows several weeks of mild weather in the Spokane area.
