Experts are saying it is the worst tornado ever to hit Oklahoma. At over two miles wide, it completely flattened a Oklahoma City suburb.
If they are right, the tornado that hit today was an F4 class sytem on the Fujita instensity scale, meaning that the winds were clocking in at over 200 miles per hour at the peak of the storm.
The strongest winds on Earth, over 300 miles per hour, were found in the May 1999 tornado outbreak that killed 141 people in Oklahoma.
The damage from a system like this is incredible.

Rescue searches are being attempted to pull people out of the rubble.
