vs tornado

It was wind, wind like the sound of a train, with the low belly roar of a train. It was a tornado. That was it! The roar of a train meant bad wind and it was coming for him. God, he thought, on top of the moose not this — not this.
  But it was too late, too late to do anything. In the strange stillness he looked to the night sky, then turned back into his shelter and was leaning over to go through the door opening when it hit. Later he would think of it and find that it was the same as the moose. Just insanity. He was taken in the back by some mad force and driven into the shelter on his face, slammed down into the pine branches of his bed.
  At the same time the wind tore at the fire and sprayed red coals and sparks in a cloud around him. Then it backed out, seemed to hesitate momentarily, and returned with a massive roar; a roar that took his ears and mind and body.
  He was whipped against the front wall of the shelter like a rag, felt a ripping pain in his ribs again, then was hammered back down into the sand once more while the wind took the whole wall, his bed, the fire, his tools — all of it — and threw it out into the lake, gone out of sight, gone forever. He felt a burning on his neck and reached up to find red coals there. He brushed those off, found more in his pants, brushed those away, and the wind hit again, heavy gusts, tearing gusts. He heard trees snapping in the forest around the rock, felt his body slipping out and clawed at the rocks to hold himself down. He couldn't think, just held and knew that he was praying but didn't know what the prayer was — knew that he wanted to be, stay and be, and then the wind moved to the lake.
