DULUTH, MN (KDAL) - Road conditions have deteriorated as snow moved into the Twin Ports area during the late morning. Visibility is also restricted and motorists are advised to slow down and drive with your headlights on. The Minnesota State Patrol says even though the snow is heavy and wet, drifting is also occurring. Patrol Sgt. Curt Mowers says many SUV and pickup drivers are going way too fast. Not many crashes at this point but several vehicles have slid off the road. A Winter Storm Warning continues in the area until 4 a-m Friday.
