@cellmania: The Tri-State Tornado was truly a horrific event. The twister was moving at speeds of over 70 mph and wind speeds between 250 and 300 mph. For most areas, there was absolutely no warning of the approaching storm until it was already there.
The tornado had a 219 mile long path of destruction and, in some places, was a mile wide. It lasted for three hours. A school in West Frankfort, IL was completely leveled. The neighboring town of Parrish was 90% destroyed.
As stated, there were hundreds of people killed. There were 2,000 more that were injured. 15,000 homes were completely destroyed. No storm to this day has matched the devastation that was left by the Tri-State Tornado.
