Local Hazard History
Oklahoma City is the most tornado-tested major city in America. On May 3, 1999, the Bridge Creek–Moore F5 tornado tore through the metro's southern suburbs; a mobile Doppler-on-Wheels radar clocked winds near 302 mph (later analyzed as high as 321 mph) — the fastest winds ever measured on Earth — and the storm killed 36 people. Fourteen years later, on May 20, 2013, an EF5 tornado struck Moore again, killing 24 people — including seven children when a wall collapsed at Plaza Towers Elementary School — and causing roughly $2 billion in damage. The metro also gets giant hail and damaging straight-line winds with spring supercells, and winter brings the other Oklahoma extreme: ice storms that snap power lines and trees and can leave neighborhoods dark for days.
