A narrow band of lake-effect snow is causing travel problems in northwestern Indiana.
The heaviest snow is hitting LaPorte and Porter counties along the southern edge of Lake Michigan. The National Weather Service says snow was falling at a rate of 2 to 3 inches an hour.
Meteorologist Gino Izzi of the National Weather Service in Romeoville, Ill., expects the heaviest snow to hit Porter County through midday Tuesday, and LaPorte County could see up to a foot of snow by Tuesday afternoon.
Indiana State Police say there are numerous slick spots on Interstate 94 and the Indiana Toll Road. Police had to close a more than 15 mile stretch of I-94 in both directions for several hours Monday night. Local police also report numerous weather-related accidents.
