The massive tornado that cut a wide and deadly swath through a suburban Oklahoma City town was a top category EF5 system with winds over 200 mph (321 kmh), a weather official told AFP Tuesday.
"It's an EF5," the most powerful tornado classification, said Kelly Pirtle of the NOAA national Severe Storms Laboratory in Norman, Oklahoma, of the wedge tornado that struck Moore, Oklahoma on Monday.
"We have looked at the damage, and estimated windspeeds, and they've determined that the damage is EF5," she added by phone from Norman.
