“It’s doing damage. Major damage... This is an F5 right now,” one of the storm-chasers said in a shaky voice.
Just three minutes after the tornado touched down in Oklahoma, Chance Coldiron and Justin Cox of Fast Unit 70 already knew that they were witnessing a monstrosity. The above video shows an eerily clear view of the first 10 minutes of the Moore tornado, as it develops from a thin, wispy funnel into a terrifying, deadly tornado.
"This one is just getting stronger, and stronger, and stronger," one of the storm chasers observed around minute 6:30 as the twister turned. A close-up reveals dark gray clouds of debris, visible from miles away.
Those early observations were correct. Experts estimate the F5 tornado caused about $2 billion dollars worth of damage, destroyed up to 13,000 homes, and killed 24 people.
