Heavy snow is expected for the rest of the morning with increasing north winds and a major impact on travel.

This Afternoon: Very heavy snow at times with snowfall rates between 1” – 3” per hour. Strong winds gusting to 50 - 60 MPH at times will cause blowing and drifting of the snow and also reduce visibility to near zero at times. The strong winds may also cause some power outages.
