Environment Canada issues severe weather alerts

Environment Canada says all areas can expect extreme cold, with windchills ranging from -30C to -40C this afternoon.

Many areas may also see an additional 15 to 30 centimetres of snow by Tuesday night, along with blowing snow creating treacherous road conditions.

Exposed skin could freeze in less than five minutes in these conditions, the federal weather agency warns.

Environment Canada Warning Preparedness Meteorologist Geoff Coulson says temperatures didn't drop as significantly as expected because of the squall activity. He says the concern now continues to be the blizzard and wind chill warnings.

Coulson says this weather system should continue through today and tonight into tomorrow morning before diminishing.
