A derecho is often described as an inland hurricane because of the strong winds and damage the storms can cause.

"The storm has no eye, and its powerful winds come across in a line. That can cause widespread overall damage and smaller pockets of severe damage.

To be classified as a derecho by the National Weather Service, the storms must have wind gusts of 57 mph or greater and wind damage from the storm must span at least 400 miles."
