Imagine a thunderstorm with a huge updraft in the center. You are keeping a literal ton of moisture hanging in the air, turning into hail and ice. Suddenly, a whole storm just dumps over you when the updraft ends.
It’s extremely damaging. It’s like you get a whole monster storm dumped on top of a 5 mile diameter area, all at once. 5-8 inches of rain just drops in 2 minutes.
Microbursts are pretty awesome but they aren’t caused by a bunch of woke, broke environmentalist wackos looking for government grants. They have been around forever. A huge one hit the airfield at Fort Hood back in the late 80s and wiped out a bunch of helicopters. And I mean a bunch of helicopters.
