Environment Canada is predicting a blizzard tonight. And I don't mean a "ooh, it's snowing kinda almost hard" Vancouver-style "blizzard", but an actual 90 Km/h winds, up to 20 cm of new snow, blowing snow, -20 °C blizzard. Vancouver is not set up for this kind of thing. This is an unusual city in that a great deal of the electrical infrastructure, even downtown, is done with suspended wires and telephone poles. High-wind plus sub-zero temperatures plus snow plus above-ground electrical wiring - you do the math.
