A derecho is a widespread, straight-line windstorm that is associated with a fast-moving band of severe thunderstorms. Generally, derechos are convection-induced, forming in an area of wind divergence in the upper levels of the troposphere, within a region of low-level warm air advection and rich low-level moisture.
Derechos travel quickly in the direction of movement of their associated storms, similar to an outflow boundary, except that the wind is sustained and increases in strength behind the front, generally exceeding hurricane-force.

We recently had one here in central VA, USA. I had never heard of a derecho before our storm. It wasn't predictable and it was very intense with lots of property damage and widespread power outage.

We had one here in July of 2009. The scariest storm I've ever been in, and I've been in a lot. As the above poster said, lots of damage to houses, cars, etc. and no power for days. It happened early in the morning and by later that evening, I did happen to take some of the most amazing cloud pictures ever.
