Yesterday I had to use it too. I was using a 2002 Wipika C-bar and a Toro8.
Just look how strong the wind was from 6 to 7 o'clock(page only visible for a couple of hours because of refresh):

Well, it shows windforce up to 22 m/s. Normally you have to extract 1 beaufort to have the actual windforce. Still a LOT of wind!!!!!!!!!
