Click da green flag two times (it removes wind sound) then set wind. I recommend not setting the wind very fast because it will not show the tornadoes. TORNADO SCALE: EF0 to EF6 (320 mph)
Note- once a tornado is hidden u cannot remake it. fore example, if you go above 85 u will not be able to make EF0 again. There is a glitch where the EF5+ winds play, don't mind that.
