Lake-effect snow showers will be heavy at times this afternoon and evening. Localized whiteouts and snowfall rate of about 1 inch per hour are expected through 10 p.m.

Additional accumulations through tonight will vary from as little as 1 inch to as much as 6 inches, according to the National Weather Service office in Grand Rapids.

The snow showers will occasionally reduce visibility to less than a half-mile. Travel will continue to be difficult as extremely cold temperatures have made roads icy, and road salt and chemicals are not working properly.

There have been numerous slide-offs and crashes, and and these are expected to continue into this evening. Motorists are urged to slow down and leave plenty of space between cars.
