AUSTIN (KXAN) — An early morning fire caused exterior damage at Travis Early College High School in south Austin.

Austin Fire responded to the fire at 4:49 a.m. Sunday. They said the cause was electrical.

AFD said the damage was limited to the exterior on the roof and HVAC system. No cost estimate for damages is available yet.

In a letter to families, Travis ECHS principal Erick Posadas said classes will not be affected Monday. Posadas wrote the fire was contained to the athletics building roof, which is separate from the main building.

“We are working closely with Austin ISD Central Office to assess the extent of the damage and plan for restoration,” Posadas wrote.
