The Washington State Patrol reported numerous spinouts on I-5 from Smokey Point north to Stanwood on Saturday night as another round of snow hit Snohomish County.
“People are going off into the ditch,” Trooper Keith Leary said. “We haven’t had any major collisions but most are caused by speeds too fast for conditions.”
Drivers should make sure they watch their speed, increase their following distance, and make sure they’re not hitting their brakes because the roads are extremely icy, he said.
“People need to be on their best driving behavior,” he added.
The worst conditions were on I-5 from Mount Vernon to the Canadian border, according to the state Department of Transportation.
Marysville was hit hard, with seven streets closed, including Getchell Hill, Sunnyside Boulevard and Soaper Hill Road.
Road crews will be out clearing streets until midnight and are expected to resume plowing at 6 a.m. Sunday, according to the Marysville Police Department
In Everett, where about an inch of snow fell Saturday, trucks spread salt and sand and plowed 15 miles of streets, spokeswoman Kate Reardon said.
Seven plows were out clearing streets at 8 p.m.
Spinouts were also reported on Mukilteo Speedway on the hill leading to the Mukilteo ferry dock.
