The National Weather Service is confirming that an EF-1 tornado touched down near Canyon Lake just after 1 a.m. Tuesday.
The twister was on the ground for about two minutes and traveled less than half a mile in a path 250-yards wide.
It was part of a storm system that moved through the Hill Country, bringing rain, hail, and powerful winds.
The tornado had maximum wind gusts of 100 miles an hour, and blew down power lines, damaged trees, and tore off part of a roof.
No injuries were reported.
The twister was part of a line of storms that was pushing through Texas. Earlier in the night damage was reported in the town of Bertram.
The National Weather Service says the damage was caused by straight line winds of 75-miles an hour and a microburst that caused the damages when the storm hit late Monday into early yesterday. A part of the old A.B. McGill building built in the 1880s collapsed during the storm. Due to public safety concerns, demolition started yesterday of the historic structure's remnant that was left standing.
