A winter storm that brought snow, sleet and freezing rain to a large swath of the Midwest swept into the mid-Atlantic and Northeast on Thursday, causing treacherous travel conditions, prompting school delays and closures and potential power outages for millions of Americans.

Storm Freya whipped from the Midwest into the Northeast Thursday, coating roads in slick ice from Baltimore up the I-95 corridor, making for dangerous commutes and forcing school closures and delayed openings.

Multiple drivers had to be rescued after getting stranded in the floodwaters, authorities in West Virginia said.
