Up to 6 inches of snow fell over Skagit County this morning, creating trouble for the morning commute.

“We’re definitely stretched right now as far as being able to (plow) all the roads,” state Department of Transportation spokesman Dave Chesson said. “When it’s snowing this heavily, if you can avoid traveling that’s the smart thing to do.”

The National Weather Service reported that Skagit County was hit hardest by the latest snowstorm.

Debbie Allen, a cooperative observer for the National Weather Service and the foreman of the Sedro-Woolley wastewater treatment plant, said on Wednesday morning that 3.9 inches of snow fell at the plant.

State and county plows and sanders will be out all day and into the night to catch up with the snow and ice on the roads, officials said.

County Road Operations Manager Cliff Butler said he doubted more remote roads, such as Baker Lake Road or roads in the Lake Cavanaugh area were fully cleared as of 9 a.m.

“It’ll take a while to get it all opened up again,” Butler said of Lake Cavanaugh.

Another heavy snow band was approaching Skagit County from the Oak Harbor area shortly after 9 a.m., Chesson said.

A winter storm warning remains in effect for Skagit County and surrounding areas until 10 a.m. Thursday. Weather Service meteorologist Dennis D’Amico said the area could get another 2 or 3 inches of snow by then. Everett and Whidbey Island have reported rain mixed with the snow, D’Amico said.
