(CNN) — More than 1,600 flights were canceled and many more delayed on Tuesday as a brutal ice storm continued to hit parts of the South and central United States, bringing a second day of transport problems.
As wintry conditions affected an area from Texas to West Virginia, airplane tracking website FlightAware reported that more than 1,600 flights had been canceled within the US and more than 2,600 delayed by about 1:30 p.m. ET.
Texas has been 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 disruption, according to FlightAware, with Dallas Fort-Worth seeing the bulk of cancellations. As of 1 p.m. ET, more than 800 flights to or from DFW were canceled.
Nashville International Airport in Tennessee was also seeing significant cancellations, with about 130 flights canceled by 1 p.m. ET.
Southwest, American and regional carriers Envoy Air and SkyWest have been the most affected airlines.
Texas-based Southwest and American airlines had both canceled more than 500 flights by early Tuesday afternoon, representing 14% and 16% of their schedules, respectively.
On Monday, Southwest, which experienced an operational meltdown over the holidays, canceled about 12% of its schedule. American canceled 6% of its flights. Across all carriers, more than 1,100 flights were canceled on Monday, with more than 6,000 delays.
DFW airport tweeted Tuesday that it is well prepared for the winter weather: "Airport runways, roadways, bridges, and pedestrian walkways have been and will continue to be treated for any potential ice to ensure safety."
The heaviest ice accumulation is forecast across large portions of Texas, which could see one- to three-quarters of an inch through Thursday morning. One-quarter inch of ice is possible across a wider swath of the region, including southern Oklahoma, Arkansas, northwestern Mississippi and parts of Tennessee.
"I encourage Arkansans who are experiencing winter weather to avoid travel if possible and heed the warnings of local officials," Arkansas governor Sarah Huckabee Sanders tweeted on Monday.
