Derechos – Who Knew?
July 11, 2012 — Until a derecho (pronounced "deh-REY-cho") found its way to our fair city June 29, few people had heard of them.
The National Oceanic and Atmospheric Administration defines a derecho as a widespread, long-lived windstorm that is associated with a band of rapidly moving showers or thunderstorms. While causing damage much like a tornado, a derecho's destructive winds move in a straight line, while a tornado's winds are more twisted. To be classified as a derecho, its path must extend more than 240 miles and it must produce winds of 58 mph or greater along most of its length.
Such is what happened in Virginia, leaving more than 1 million without power and 568 roads closed at the onset and causing 13 fatalities to date.
