Extreme Weather Events

[Targan]

I thought about putting OT: in front of this thread's title but then I realised it correlates well with the game. In my city today we had a freak storm that brought monsoon-like conditions for some of the day (hot and sticky, high humidity, thunder and lightning, rain) then came a cold snap and either very heavy rain or in some areas hail. And not just any hail, hail stones literally the size of golf balls which pretty much destroyed my fiance's car's windscreen and dented the hell out of the roof and bonnet.

I know we've talked about the game mechanics of extreme high and low temperatures, exposure to harsh environments and the like but there are a few effects we haven't yet touched on. For instance, at what wind speeds do heavier and heavier objects start to get picked up by the wind and flung about? What damage to a person would different wind-flung objects do? How much hurt could a fist-sized hail stone deliver? What damage would a character suffer if struck by lightning? Would a 100-knot sand storm kill you by choking/burying you or would having your skin abraided away kill you first?

Discuss if you will.
