An ice storm is a type of winter storm characterized by freezing rain. It occurs when a layer of warm air is between two layers of cold air. Frozen precipitation melts while falling into the warm air layer, becoming rain, and pass through a thin layer of cold air just above the surface. This thin layer of air then cools the rain to a temperature below freezing (0 °C). When the supercooled drops strike ground below 0 °C or anything else below 0 °C (power lines, tree branches, aircraft or my yard table (photo) this morning), they instantly freeze, forming a thin film of ice, hence freezing rain. Location and geography create above Montreal (where I live by the way) the ideal conditions for this phenomena #humpf. Each winter it occurs 8 to10 times and this night was just the first one. But in 1998 Montreal had the worst ice storm in history, leaving people under very extremes conditions for almost 10 days in a roll. That became a super interesting Discovery Channel Documentary. I recommend it, at least watching the 1st part http://www.youtube.com/watch?v=PEyfj4yzh7I&feature=related.
Part 5 talks about how it was affecting (and killing) the human body.
Part 6 about the infrastructure (airports, power lines etc).
I wonder why they didn't say that during the Immigration process....
