Other forms: derechos
A derecho is a powerful, widespread, fast-moving, and destructive system of storms with extremely high-speed, straight-line winds. A derecho produces a swath of wind damage more than 240 miles long, and has wind gusts of at least 58 miles per hour.
The name of this severe weather event is derived from the Spanish word derecho, which means "straight." Unlike tornadoes and hurricanes, which have rotating winds, derechos have winds that blow in a straight line. These storm systems occur mainly in North America, especially in the central and eastern regions of the United States, but they have also been documented in Europe, Asia, and South America. Most derechos occur in the warmer months, from late spring through summer.
