Historic Storm Strikes U.S. East Coast

Video description

From the National Oceanic and Atmospheric Administration:

A week-long heat wave and an upper level disturbance over Chicago combined to spawn an historic storm featuring a rare and destructive phenomenon known as a derecho.

A derecho is a widespread, long-lived wind storm that is associated with a band of rapidly moving showers or thunderstorms. Although a derecho can produce destruction similar to that of tornadoes, the damage typically is directed in one direction along a relatively straight swath. As a result, the term “straight-line wind damage” sometimes is used to describe derecho damage.

By definition, if the wind damage extends more than 240 miles and includes wind gusts of at least 58 mph or greater along most of its length, then the event may be classified as a derecho.
