MOORE, Okla. - KFOR-TV Chief Meteorologist Mike Morgan and Chopper 4 pilot Jon Welsh were on the air as a tornado formed and touched down in Moore, Oklahoma, Wednesday.

Moments after Morgan pointed to what he called a "gustnado" of debris, rotating winds from the storm started snapped power lines causing electrical explosions and other destruction on screen.

The tornado destroyed homes, flipped semis on their sides and tore the roof off an elementary school.

As the storms moved northeast, one person was killed in a mobile home park just outside of Tulsa, about two hours from Oklahoma City.
