Motorists should use extreme caution if traveling in Southwest Mississippi, said Lincoln County Emergency Management Director Clifford Galey.

“Bridges, overpasses, county roads are icing over,” Galey said. “If people don’t need to be on the roads, they should stay off.”

He said at least three collisions have been attributed to driving in the weather. He expects the snowfall to accumulate to an inch or more by 8 p.m.

Galey said classes are canceled for Wednesday in the Brookhaven and Lincoln County school districts as well as at Brookhaven Academy.

Lawrence County School Superintendent Tammy Fairburn posted on social media that classes there will be canceled Wednesday, too.

Wesson Attendance Center Principal Marilyn Phillips said Copiah County schools will be closed, also.

All campuses of Copiah-Lincoln Community Community Colleges will be closed, said Natalie Davis, director of public information.
