Around here 30-40mph winds is just a decent breeze. We get 60+ mph winds most winters, have seen 100mph gusts even.
One winter I was working on a shed. Ran over to Lowes and bought a few sheets of OSB, Was a nice day. Left at 2 for work (worked 3rd shift 3-11pm) and didn't think much of leaving the OSB in the truck. Got home that evening, was blowing hard.
The sheets flew out of the truck, busted my back window and scuffed up the cab pretty bad. I found one sheet about 300ft away stuck in the tree tops. It flew out of the truck, over my house and into the trees! Found another sheet that summer in the woods by my neighbors. The rest of them, never found them.
Wind doesn't bother much when logging, but we are not hand falling. I've had a tree hit the roof of the skidder, even with my ear muffs on it was quite loud.
