A rare frigid storm charged through Texas and the northern Gulf Coast on Tuesday, blanketing New Orleans and Houston with snow that closed highways, grounded nearly all flights and canceled school for more than a million students more accustomed to hurricane dismissals than snow days. The storm prompted the first ever blizzard warnings for several coastal counties near the Texas-Louisiana border, and snowplows were at the ready in the Florida Panhandle. In the Texas capital, two people died in the cold weather, according to a statement from the city of Austin. No details were provided, but the city said emergency crews had responded to more than a dozen “cold exposure” calls. Officials said one person died from hypothermia in Georgia.
