They are like a mini-tornado, usually only a few feet wide and the winds are barely strong enough to shuffled around debris on the ground like leaves, paper, they will cover you with dirt if you get caught in their path, so of course kids love 'em.
We occasionally get a wind shear that will carve a destructive path at ground level. When one of these downburst winds hit my little community a few years back, the local fire station recorded the wind speed at 85 mph before the gauge snapped off. The wind flattened 100ft long poultry barns, ripped the roofs off buildings, tore down fences and snapped off power poles. While it only lasted maybe 20 minutes, the noise was deafening, the blowing rain, dirt and debris made visibility zilch.
Very scary. I sure wouldn't want to go through hurricane force winds that lasted for hours. The unrelenting fears and stress would probably give me a heart attack. I hope people listen to the warnings and try to get out, and TPTB better have the systems in place to handle mass evacuations.
