"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."
The Midwest US had a big derecho that blew through a couple years ago and knocked over probably half the trees in my part of the state. Some communities were without power for weeks, it was a mess.
Damn, that’s wild. I’m in CO, and apparently we’ve only ever had one. It’s too dry here and the mountains break them up.
