The Texas Department of Public Safety reported a tornado around 6 p.m. in the town of about 400 residents located in the northeastern part of Brown County.
The National Weather Service will survey the damage to see if it was indeed caused by a weak tornado.
The storm damaged the Blanket school just before 6 pm, ripping part of the gym roof off and causing quite a bit of damage to the west side of the school. Classes had been dismissed at the time.
Many trees and utility polls are also down in the Blanket area.
The Blanket superintendent tells KTXS News that classes have been canceled for the rest of the school year but graduation will be held. This was to have been the final week of classes anyway in Blanket.
