It sounded like a freight train barreling toward his house. “I was going to get my wife and go into the basement. We didn’t have time,” Michael Haggerty said of the tornado that tore through his Doylestown neighborhood last August. “(My wife) was in the family room right by the window that got blown away. I just jumped on top of her,” Haggerty said. “I didn’t know what was going to happen. It was gone in 15 seconds. It was that quick.” Quick. And increasingly common, records show. Pennsylvanians have come to expect floods, snow storms, and the occasional hurricane. Now, reports of tornadoes also are on the rise.
