Breaking Down Derecho

National Weather Service looks at the phenomenon that wreaked havoc in Fairfax County.

While Fairfax County picked up the pieces left by the derecho in late June, the National Weather Service in Sterling picked apart the rare storm.

NWS analysts say in a case study of the June 29 weather event that derechos are relatively uncommon to this region, especially ones of this magnitude. Typically, the Mid-Atlantic region might experience a derecho once every two to four years, the report says. The last significant derecho in our region occurred on June 4, 2008. 

More than 20 deaths have been blamed on the storm, which stretched from Indiana to North Carolina.
