More than 220 million people across the United States are facing dangerous cold that will also open the door for a potentially historic and crippling winter storm that could deliver snow as far south as Florida and the Gulf of Mexico.

A winter storm was on a track to sweep through Texas and Louisiana, across the Gulf Coast and deep into Florida, significant snow and ice in tow.
