My uncle was a truck driver. A couple of years ago, while he was driving Cabbage Hill in eastern OR (over the Blue Mountains on I-84 just east of Pendleton), the winds were blowing bad enough the State Troopers were closing down the pass to trucks. Just as my uncle approached the shut down area, the wind whipped hard enough to topple his truck onto the driver's side, and blow it over from the right lane to the left lane up against the guardrail. The guardrail held, thankfully, otherwise he would have been blown over the edge and down a cliff onto the westbound lanes.
It was blowing so hard, that when he attempted to get out of the cab, the wind ripped the door out of his hands and tore his glasses from his face.
The troopers said it looked like a microburst hit at that point.
