Snow and sleet started falling in Texas as officials begin to close schools and airports. Snow and ice could bring major travel disruptions and power outages from Texas to Florida.

A rare winter storm churned across the U.S. Gulf Coast on Tuesday, breaking snowfall records more than a century old in a southern region where flurries are unusual, as much of the United States remained in a dangerous deep freeze.

President Donald Trump on Monday signed an executive order demanding the body of water that runs along the United State’s Southeast Coast be renamed to the Gulf of America.

As part of a torrent of decisions he issued hours after taking office, President Donald Trump declared that the name of America’s tallest mountain be changed from Denali to Mount McKinley, and that the Gulf of Mexico be renamed “The Gulf of America.”

The order Trump signed instructs the Interior Department to update the Geographic Names Information System to reflect the renaming of the Gulf and remove all references to the Gulf of Mexico. It says all federal references to the Gulf of America, including on agency maps, contracts, and other documents and communications shall reflect the renaming.
