DALLAS (AP) – A mock storm dubbed Hurricane Tejas will help first responders practice air emergency evacuation methods at some major Texas airports.

Department of Public Safety Trooper Robbie Barrera says the drill began Wednesday and runs through Thursday. The exercise involves people supposedly needing to leave South Texas.

Barrera says the 2016 Rio Grande Valley evacuation exercise is a chance to practice and evaluate plans for evacuating and sheltering people, some with medical issues, using aviation and ground resources.

The drill involves Dallas-Fort Worth International Airport, Dallas Love Field, Austin-Bergstrom International Airport and Kelly Field Airport in San Antonio.

Barrera says most people will not be aware of the disaster drill because the exercise involves airport areas where there’s no commercial traffic.
