ERIE, Pa. (WPVI) — At least five states are under a winter weather advisory Monday morning.

Parts of Pennsylvania, Ohio and New York are expecting up to two meters of snow in the coming days.

A lake-effect storm has already dumped more than two feet of snow on Erie County, Pennsylvania over the weekend.

Gov. Josh Shapiro signed a disaster declaration and called in the National Guard to help.

Pennsylvania State Police responded to more than 200 traffic accidents between Friday and Saturday alone, Shapiro said.

“At the county’s request, I called in the Pennsylvania National Guard — now on scene — to assist stranded drivers and ensure emergency responders can get to the people who need them,” Shapiro said in a statement.

Erie County, Pennsylvania Executive Brenton Davis said the local disaster emergency will remain in effect until the middle of this week.

Davis said county buildings, including courthouses, in Erie County will remain closed Monday and Tuesday and that officials are advising school districts to remain closed as well. He said residents should minimize travel.

Gaylord, Michigan, recorded 24.8 inches of snow on Friday, marking the snowiest calendar day on record and breaking its previous record of 17 inches set on March 9, 1942.
