On Sunday, October 20, at 9:30 p.m., 11 confirmed tornadoes touched down in the Dallas area.

The most fatal one, classified as an EF-3 with 140 mph winds, traveled through northern Dallas, crossing route 75, highway 635, and heading toward Preston. It damaged buildings, schools, homes, trees, and power lines, cutting power for more than 100,000 people in the area. The storm also included heavy rain, lightning, and baseball size hail.

The city lost about $2 billion in damage expenses–the costliest in state history. Fortunately, there were no serious injuries.

Unfortunately, Texas wasn’t the only state that was hit by a series of twisters on that Sunday–Oklahoma and Arkansas also experienced their force. Two people (one in each state ) were killed by trees falling into their homes.
