Inbound flights continued to be delayed at their origin at an average of about 6 hours, according to Flight Aware.
Houston Hobby Airport is also being affected, as well as other major airports across the state. About 200 flights were cancelled out of the airport in southeast Houston.
Bill Begley, of Houston Airport System, said about 180 people are stranded at Bush Intercontinental. The airport is providing cots, food and toiletries to those passengers.
At Hobby, officials are looking at food and shelter options for any passengers who have nowhere to go, according to Begley.
If you plan to head to the airport today, make sure you check the status of your flight.
