Millions of people across the northern Gulf Coast braced Tuesday for a rare winter storm that’s expected to scatter heavy snow, sleet and freezing rain around the Deep South as a blast of Arctic air plunges much of the eastern U.S. into a deep freeze.

Winter Storm Enzo has brought rare, record-breaking snow to parts of the Gulf Coast, snarling travel and resulting in historic snowfall totals from New Orleans to Florida. New Orleans picked up 8 inches, making it the heaviest snowfall there in modern day records (since 1948) and the city's biggest total in over 100 years.

A rare frigid storm is charging through Texas and the northern Gulf Coast, blanketing New Orleans and Houston with snow, closing highways and grounding nearly all flights.
