I never in my life thought there would be a tornado warning in BC much less in Vancouver. I always figured the climate and the latitude prevented that. Guess I was wrong.
IIRC, anywhere it is possible for tornadoes to form. All it takes is 3 weather conditions to occur, and you get a tornado. (heating lift, upper cooling, and a cross or shearing wind)
But these conditions happen more regularly in certain areas.
