The man at the very end of the clip whose garage and car were crushed observes that his house is fine. In other words, there was enormous tree damage but not physical damage to buildings (other than that caused by trees). If the wind was so powerful, why are the buildings intact? For that answer, you would have to understand that pollution is killing trees...there is an introduction to that, here.
(There's an ad first, of course.)
Update: The video below of a lethal accident in Virginia from Bill Hicks is incredible and tragic - no rain, no wind. Click on this link for the source.
