Commuters are dealing with icy roads in many parts of Massachusetts as a winter storm moves in.

The storm began as a mix of snow and freezing rain in much of the state, although the precipitation is expected to change over to mostly rain — heavy at times — as temperatures rise during the day.

State police spokesman David Procopio said troopers responded to numerous crashes and spinouts caused by icy roads, some involving their own cruisers.

Among the hardest hit areas were north and west of Route 128. Drivers were urged to reduce speeds and leave extra time.

The National Weather Service posted a flood watch for urban and poor drainage areas, and a coastal flood advisory for the midday high tide cycle from 11 a.m. to 3 p.m.
