A “small tornado” caused severe damage Tuesday evening to a NASA building on Redstone Arsenal but resulted in no injuries, according to the arsenal Garrison.

The incident occurred about 7:30 p.m. as a line of severe thunderstorms moved through the area. Building 4604 at the Marshall Space Flight Center, which is unoccupied, suffered “severe damage to the exterior,” a Garrison news release stated.

“We are grateful that no one was injured during this severe weather event,” Garrison Commander Col. Erin Eike said. “Our team is working diligently to assess the damage and ensure the safety of all personnel.”

The area around Building 4604 has been secured.

Redstone officials are advising personnel to watch for potential hazards and to report any damage or safety concerns to their supervisors or the Directorate of Emergency Services, 256-876-2222.
