I can corroborate the fact that winds can be strong enough to destroy equipment.
Back in 72/73 BAS installed a small wind generator on South Georgia for a two-man glaciologist's hut (up on Mount Hodges I believe it was). Its designers had said it was tested up to wind speeds of 100mph. It was destroyed just a few months after installation when the winds at the base (at sea level) were gusting to 80 knots.
