Weather: Dragons of Chaos - S40.E15

The nature of weather is so complex that it is really a system of chaos. Weather is often benign, but occasionally the chaos spawns fierce dragons. Severe weather - violent storms, floods and droughts - is largely beyond human control, and can be cruel. Few need reminding of the 1987 tornado that killed 27 people in Edmonton, the flooding of the Saguenay region in 1996 and the Red River in 1997, and the 1998 ice storm in Quebec.
