Canceled flights: 1,800 cancellations Tuesday due to weather

(CNN) — More than 1,800 flights were canceled and many others delayed on Tuesday as a severe ice storm continued to batter parts of the southern and central United States, leading to a second day of transportation problems.

As wintry conditions affected an area from Texas to West Virginia, aircraft tracking website FlightAware reported that more than 1,800 flights were canceled in the United States and 3,900 delayed by around 6 p.m. ET .

More than 900 flights on Wednesday had already been canceled early Tuesday evening.

Texas was particularly hard hit.

Three of the state’s airports — Dallas-Fort Worth International (DFW), Dallas Love Field (DAL), and Austin Bergstrom International (AUS) — are experiencing significant disruptions, according to FlightAware, with Dallas Fort-Worth seeing the bulk of cancellations. As of 5 p.m. ET, nearly 1,000 flights to or from DFW have been canceled.

Nashville International Airport in Tennessee has also seen significant cancellations, with about 140 flights canceled as of 6 p.m. ET.

Southwest, US and regional carriers Envoy Air and SkyWest were the hardest-hit airlines.

Texas-based Southwest and US airlines had both canceled nearly 600 flights Tuesday night, representing 15% and 19% of their schedules, respectively.

On Monday, Southwest, which experienced an operational meltdown over the holidays, canceled about 12% of its schedule. American has canceled 6% of its flights. All carriers combined, more than 1,100 flights were canceled on Monday, with more than 6,000 delays.

DFW Airport tweeted on Tuesday that it was well prepared for winter conditions: “The airport’s runways, roads, bridges and walkways have been and will continue to be treated against any potential ice in order to Ensure the security”.

The heaviest ice accumulation is forecast over large parts of Texas, which could see one to three-quarters of an inch through Thursday morning. A quarter inch of ice is possible over a wider swath of the region, including southern Oklahoma, Arkansas, northwestern Mississippi and parts of Tennessee.

“I encourage Arkansasians experiencing winter conditions to avoid travel if possible and heed warnings from local authorities,” Arkansas Governor Sarah Huckabee Sanders tweeted Monday.
