SEATTLE -- The Pacific Northwest got the white Christmas it wanted, but now all that snow and slush is freezing up again.

Monday night, plows were scrambling to clear the roads as parts of the region braced for black ice and freezing fog.

Drivers were bracing for a tricky Tuesday morning commute.

"It's so important now because we're not really used to seeing all this snow in the Pacific Northwest,” said driver Edward Newell. “It's a beautiful sight but a little bit more cautious driving.”

The Washington Department of Transportation is trying to get ahead of the freeze.

Officials said three-dozen crews are plowing and treating roads—with more crews working the hardest hits areas from the Christmas Eve snow.

First, crews working 12 hour shifts will clear left over snow, then they will throw down de-icer.

"The roads have been pretty clear especially the highways. It's just those residential areas that we're you're know, worried about,” said driver Martin Hehn.

Steven Soliz who was driving from Montana msaid he is more concerned about the drivers he has to share the road with.

"That's my biggest concern is a lot of these cats from Seattle don't really know how to handle the snow,” said Soliz.

WSDOT said the agency also has about a dozen incident response crews to help people who spin out or get stranded on the roads.

The agency encouraged drivers to use caution on the highways.
