What the heck is a "derecho"? (Part 3)

I saw this link with this amazing picture and just had to share.

On June 29, 2012, a violent wind storm system – called a derecho – advanced eastward across Indiana, Ohio, West Virginia, Virginia, the District of Columbia, Maryland, and in parts of New Jersey. It produced hurricane force winds that gusted as high as 91 miles per hour in Fort Wayne, Indiana. Millions of people were left without power as trees snapped on power lines. The Storm Prediction Center (SPC), reported nearly 800 wind reports from this derecho. Virginia Governor Robert F. McDonnell declared a state of emergency Saturday, June 30, 2012 – which also affected Washington DC – after the storm devastated the region. In fact, McDonnell announced that the derecho that pushed into Virginia made it the largest non-hurricane power outage in state history. As of now, at least 13 people are known to have died from this destructive storm system, with six deaths reported in Virginia, two in New Jersey, two in Maryland, one in Kentucky, one in Washington D.C., and one in Ohio. As of 5 p.m. EDT on June 30, 2012 (21 UTC), at least 1.6 million people were still without power, which is bad news because residents in these areas are experiencing hot temperatures over 90°F. Check out these images and videos from this destructive and deadly derecho event.
