Record snowfall and blizzard conditions are affecting many southern US states; southeast Texas through Louisiana and into parts of Mississippi, Alabama and Florida, with conditions continuing to last through today, mostly clearing by Thursday.
"Widespread closures: Snow has closed or hindered operations at multiple airports in the South, contributing to the more than 2,300 flight cancellations into or out of US airports Tuesday – and more than 900 cancellations so far Wednesday. Large sections of Interstate 10 — the Gulf Coast’s major thoroughfare — in Texas and Louisiana are closed Tuesday as snow and some icy mix make travel difficult to impossible. Major roads were closed across the New Orleans area. Schools and government offices are closed Tuesday throughout the Gulf Coast and states of emergency are active in Louisiana, Georgia, Alabama, Florida and Mississippi."
