A Derecho is like an inland hurricane, they can be very sudden and the windspeeds can top out at 100-120 mph. That high of a speed used to be expected about once every 50 years or so. There was a really big one in 2012 that had a peak speed about 95 mph, IIRC. There was another big one in 2015 that got to 120 mph at its peak in South Dakota. This recent one peaked at 112 mph. I don't know if they're becoming more and more common for sure or not, but it sure seems that way... Derechos are more common and more destructive after heat waves. The heat waves coming by 2040, if we don't start working towards actual solutions to climate change, will probably make even these derechos seem tame. Extreme heat waves will increase in intensity and frequency even if we take radical action right now just because of delayed feedback from previous GHG. We can deal with these, we can plan for them, but it will be very difficult if society remains oriented around profit for the bourgeoisie.

I don't think Iowa is going to get any federal relief support either, but that remains to be seen.
