The Virginia and Tennessee departments of transportation are preparing for the winter weather.

We're told they have crews on-call for when the snow hits our area.

VDOT spokesperson Michelle Earl tells us crews are waiting to put salt down until after Sunday night's rain switches over to snow. Earl says that will keep the salt from washing away.

Earl suggests people stay off the roads and check road conditions before heading out Monday morning. "We do have an application on smartphones, our 511 app and you can go on there and download that and see the roads that are color-coded by the conditions on those roads. They're going to be green if there's nothing in the way to impact traffic, and then it'll go yellow, to red depending on what's happening out there," she said.

Earl tells us you can also go to www.511Virginia.org for updated road conditions.

TDOT spokesperson Mark Nagi says TDOT trucks hit the road at 6:00 PM Sunday and are adding calcium chloride to the brine tanks to fight refreezing.

TDOT tells us there are 215 trucks in east Tennessee working to clear the roads with more than 65,000 tons of salt available.
