Local 4 crews in Ann Arbor say the intensity has been picking up there Wednesday evening.
The good news is crews are out working to keep the roads safe for drivers. Ann Arbor uses an automatic vehicle location system so anyone can access an online map and track the work of snow plows throughout the city.
Color-coded in-screen icons are used to identify and track the snow plow truck activities. Solid blue means the ignition is on; Blue with green center means the truck is spreading salt and/or sand; Gray center line means the plow is down; Solid black means the ignition is off.
