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.

On Tuesday, a historic winter storm left regions of the South blanketed in snow, including Florida, Texas and Louisiana.

President Trump's Department of Homeland Security finds "an actual or imminent mass influx" of illegal immigrants at the southern border.

The amount of snow the Gulf Coast States received makes this weather system the worst winter storm in over 120 years. Before 120 years ago, record keeping was unreliable or not recorded at all.

The move comes days into Trump’s second administration. He has already signed multiple executive orders that will support his plan for a crackdown on migrants at the southern border. Among this flurry of orders, Trump signed one Monday declaring a national emergency at the southern border.

The national emergency declaration will allow the Trump administration to deploy armed forces and National Guard members to the border. Trump said troops will "repel the disastrous invasion of our country." It's unclear how many troops will be sent to the border.

The first such military flight out of El Paso, Texas, took place, bound for Guatemala with approximately 80 immigrants on board.

Meteorologists were left speechless Tuesday as record amounts of snow fell along the Gulf Coast. Here’s why it was so snowy.

President Trump issued a raft of executive orders that effectively block migrants from entering the United States and applying for asylum, closing off major legal channels for immigration.

Officials warned residents across the South that the effects of a major winter storm were not over, and that driving remained a hazard on roads frozen with slippery ice.
