 It really wasn't the wind that bothered Houston so much. It was the rain. In some places, nine and a half inches of rain fell in a very short time. The wind, of course, the damage that it did was to the power infrastructure, knocking over power lines, knocking over big, tall power transmission lines for hundreds of thousands of people, two million at one point. Then the storm moved up into East Texas, then Northeast Texas, and then finally was downgraded to a post-tropical cyclone.
