A "super derecho" of violent thunderstorms left a more than 700-mile trail of destruction across the Midwest and mid-Atlantic on Friday, cutting power to millions and killing thirteen people.

More than 600 damaging wind reports were received by NOAA's Storm Prediction Center (SPC) as the derecho took roughly 12 hours to race from northern Indiana to the southern mid-Atlantic coast.

A derecho is defined as a widespread and long-lived wind storm that accompanies rapidly moving showers or thunderstorms. The most severe derechos are given the adjective "super."

Winds gusted to 91 mph (equal to that of a category 1 hurricane) at the Fort Wayne International Airport, Ind., Friday afternoon.
