several years ago I build a three story, all concrete (walls, suspended slabs, roof) house on a mountainside in Alaska that has 175 mph straight line winds.
Hmmmm....the highest wind speeds recorded in Alaska are out in the Aleutians at 139 mph. Over land it is more like 100 mph or less.
The metrics here are a bit iffy. I know from experience that at around 100 knots, most anemometers simply blow away.
Also know from experience that power pylons over the mountain above Juneau got 80 years of wear the first winter (the replacement power line was built along the water edge).
