An F-5 tornado, $1 billion dollar hail storm: Why April 12 lives in South Texas weather infamy

April 12 is the anniversary of two of the most memorable weather events in South Texas history: A massive, deadly tornado that swept through Rocksprings in 1927, and one of the costliest hailstorms in Texas history left a mark on much of San Antonio in 2016.

1927 ROCKSPRINGS TORNADO

  • The F-5 tornado in 1927 swept through Rocksprings during the day on April 12, with winds of at least 260 mph.
  • 74 people died, while hundreds were injured. That’s approximately a third of the town’s population.
  • The tornado was on the ground for an estimated 65 miles!
  • Interestingly, you can still find debris from the storm in fields just east of Rocksprings.

  • The official cost of the storm came in at $1.36 billion, the second costliest hail storm in Texas history.
