NEW ORLEANS (AP) — A major winter storm that slammed Texas and blanketed the northern Gulf Coast with record-breaking snow moved east Wednesday, spreading heavy snow, sleet and freezing rain across parts of the Florida Panhandle, Georgia and eastern Carolinas.

Dangerous below-freezing temperatures with even colder wind chills were also expected to last over much of the week in the region. Authorities say three people have died in the cold weather.

A rare winter storm charging through Texas and the northern Gulf Coast on Tuesday has closed highways and airports and prompted the first blizzard warning for southeast Texas and southwest Louisiana.
