The misery brought on by Monday’s record-breaking winter storm continues to create havoc for travelers in the South, especially in Texas.
Austin Bergstrom International Airport announced that it has canceled all arriving and departing flights for Tuesday. Meanwhile, both Houston airports, George Bush Intercontinental and William P. Hobby, remain closed until at least midday. Dallas Fort Worth International and Nashville International Airport remain open but both caution that they expected more flights to be canceled or delayed Tuesday.
DFW led the entire world in cancellations and flight delays as of 8:30 EST on Tuesday morning, followed by Houston Bush Intercontinental. Nationwide, there were already more than 2,300 flight cancellations and close to 300 delays, according to FlightAware.com. Hobby, Austin, and Nashville were also in the top 10 worldwide. Dallas-based Southwest had the most cancellations of any airline in the world, followed by Fort Worth-based American.

Meanwhile, nearly 4 million homes and businesses were without power early Tuesday in Texas, where temperatures dipped into the single digits overnight.
And although snow has ceased falling in Nashville, roads throughout Middle Tennessee remain “hazardous,” the National Weather Service said.
It’s going to be pretty slick again,” Brenden Schaper, a meteorologist with the NWS in Nashville, said Monday night. “Road conditions through (Tuesday) will still be quite treacherous, so take it easy if you have to be on the roads.”
At least six people in four states died as a result of the winter storm since the weekend.
The “massive” winter storm was forecast to continue moving across the Midwest and Northeast, bringing snow, sleet and freezing rain Tuesday, and another winter storm was expected to reach south-central U.S. with snow and ice, the National Weather Service said.
As of Tuesday morning, only American and United Airlines, which both have a massive presence in the Lonestar State, still had active flight waivers. American’s is effective through Wednesday and covers 22 destinations in Texas and Oklahoma while United’s covers travel in and out of Houston through Thursday.
