The latest on the once-in-a-generation winter system off of the Gulf of Mexico from the southernmost Blizzard Warning ever issued to near-record snowfall.

Some areas of New Orleans and Houston got more than four inches of snow Tuesday morning in a historic winter storm hitting the south.

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.
