Toronto issues extreme cold weather alert

For the fifth time this winter, Toronto has issued an extreme cold weather alert as temperatures dropped overnight to below -15C.

The alert comes just a few days after unusually warm weather had us wondering where winter went.

An alert is called when Environment Canada predicts a temperature of -15C or lower, without wind chill, issues a wind chill warning for outdoor activity for people in the Toronto area, and/or predicts extreme weather conditions, such as a blizzard, ice storm or sudden drops in temperature.

Overnight Thursday to Friday, it was the second coldest night of the year.

Despite the recent warm spell, January has had three cold alerts.
