The tornado that blew through Ottawa’s east end Sunday night took both residents and expert weather watchers by surprise.

When Robert Kuhn, a severe weather meteorologist with Environment Canada, arrived at work Sunday evening, he looked back at the day’s weather data and saw nothing that would indicate an impending tornado.

“It wasn’t a classic environment,” he said. It was warm but not too hot, and the wind was “nothing to write home about.” Looking at the data, he might have thought strong thunderstorms, possibly approaching severe, and maybe some hail. “But I don’t have any indication at this point where – oh, I’ve got to go to a tornado warning or tornado watch now and see what happens.”
