Interstate 10 from the Louisiana-Texas state line to as far east as Sorrento or Gramercy could be fully open to traffic in both directions at some point Thursday afternoon, Department of Transportation and Development Secretary Joe Donahue said.

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.

By noon, the National Weather Service had reported about 4 inches of snow in New Orleans. The storm prompted the first ever blizzard warnings for several coastal counties near the Texas-Louisiana border, and snow plows were at the ready in the Florida Panhandle, according to the Associated Press.
