I have no idea. I live along the coast, and winds are a fact of life for me. I know that there are days when it's kicking up dirt devils of sand along the shoulder, and I'm bucking it using my 34/21 or even 34/23 combo on the flats. I'd say that's probably 30-35 mph winds.

During Sandy it was blowing 50 sustained out of the east. I didn't test those. There's a point where stupid begins, and it's probably 10 mph below that. You get caught out there in changing conditions, that's one thing. You adapt as best you can. Staring out in a full gale? Idiotic, IMO.

Headwinds suck the life out of you, but crosswinds can be dangerous. You can hear higher gusts coming before they hit you. I move left. I've seen other riders get blown right off the road. Sometimes they stay upright and recover. Sometimes there's a 6-8" drop from the pavement. The crash isn't too bad, unless they fall onto rocks. That has to suck.
