The National Weather Service has completed a service assessment for the June 29, 2012 derecho of historic proportions, which struck the Ohio Valley and Mid-Atlantic states. The derecho traveled for 700 miles, affecting 10 states and Washington, D.C.
The hardest hit states were Ohio, West Virginia, Virginia, and Maryland, as well as Washington, D.C. The winds generated by this system were intense, with several measured gusts exceeding 80 mph. The derecho resulted in 13 fatalities and an estimated 4 million customers lost power for up to a week.
A concurrent heat wave coupled with the loss of power following the derecho led to a life-threatening situation that claimed an additional 34 lives. The final report of this assessment may be read at: http://www.nws.noaa.gov/os/assessments/index.shtml.
Service assessments are internal reviews of the National Weather Service’s performance during certain hydrometeorological, oceanographic, and geological events. They identify best practices and areas for product and service improvements in the form of findings and recommendations.
