After a winter storm dumped up to a foot of snow across parts of the Midwest this week, the system has closed in on the Northeast region Friday as officials warn residents of treacherous road conditions.

About 7 million people in the storm’s path across the Northeast were under winter weather alerts early Friday as the first round of snow began in Vermont, New Hampshire, northern Massachusetts and Maine.

“A winter storm will continue heavy snow and freezing rain across the Northeast through Friday. Another storm will develop over the Rockies and track east Friday into this weekend,” the National Weather Service said late Thursday.
