Derecho storms impact central, south-eastern United States

 In Event News

A fast-moving line of severe storms on Friday June 20 began in Nebraska and travelled to the south-eastern coastline by Saturday morning. Known as a derecho, the storms brought strong straight line winds, hail and flooding to region.

The Storm Prediction Center defines as a derecho as a “widespread, long-lived wind storm … associated with bands of rapidly moving showers or thunderstorms”. By definition, derechos are characterized by;

  • straight-line wind damage, i.e., in one direction along a relatively straight path
  • a damage swath that extends at least 240 miles
  • wind gusts of at least 58 mph
