Understanding Derecho Storms

Definition

A derecho (pronounced deh-REY-cho) is a widespread, long-lived wind storm associated with a band of rapidly moving showers or thunderstorms. The term comes from the Spanish word for "straight," distinguishing these storms from tornadoes which feature rotating winds.

Characteristics

  • Wind damage extending more than 240 miles
  • Wind gusts of at least 58 mph along most of its length
  • Several pockets of 75+ mph wind gusts
  • Typically moves in a straight line
  • Can last several hours

Historical Context

"Derechos are relatively rare events, occurring about once every 2-4 years in any given location. However, when they do strike, they can cause damage equivalent to a major hurricane."

- National Weather Service Meteorologist
