Destructive ‘Derecho’ Storm Cut Power To Millions [Satellite Video]

Derecho thunderstorm

Here is a satellite video view of the enormously powerful and destructive derecho storm that rolled across from Illinois to the Mid-Atlantic states in the U.S. on June 29. The storm reportedly killed 22 people and cut power to 4.3 million households for days.

According to NOAA, a derecho is a widespread and long-lived wind storm associated with a fast-moving band of showers or thunderstorms. Theres storms are rare, as you can see from this list of large derechos recorded since the late 1960s.

A storm is defined as a derecho if the wind damage extends for more than 240 miles (aprox. 400 km) in one direction and includes gusts of 58 mph (93 km/h) or more for most of its path. Derecho is the Spanish world for straight. As the list of previous derechos shows, these storms, although rare, most often appear in the U.S. during late spring and summer, between April and August.

This storm caused massive power outages, and winds nearing 100 miles per hour were reported during the most intense part of the storm, between Fort Wayne, IN and Columbus, OH. Fort Wayne International Airport recorded a peak wind gust of 91 mph.
