Winter storm warnings are in effect for nearly all of Indiana. The National Weather Service says six to ten inches accumulation expected, with locally higher amounts possible near Lake Michigan. Travel is very difficult. The Indiana Department of Transportation (INDOT) is deploying more than 11-hundred plow trucks to plow and treat interstates, U.S. routes and state roads. Everyone is urged to avoid travel if possible. INDOT says due to extremely cold temperatures and sub-zero wind chills, salt will take longer to melt snow and ice, and blowing and drifting may also push snow back onto recently plowed routes.
