Ottawa to change wind chill weather warnings

- JOHN COTTER THE CANADIAN PRESS

The federal government is working on a new way to warn Canadians about the need to protect themselves from the dangers of frigid weather.

Right now, Environmen­t Canada issues wind chill warnings when cold temperatur­es and wind speeds combine to exceed health-threatenin­g thresholds, which differ depending on where you live across the country.

Under a program being developed with Health Canada, the weather office would issue an Extreme Cold Warning when temperatur­es plunge to dangerous levels, even if winds are calm.

“Working outside in the cold air there is still the possibilit­y that you can get frostbite on a nice cold day with light winds,” said Blair Morrow, an Environmen­t Canada meteorolog­ist. “We just want to provide Canadians with advance warning to take the necessary steps to protect themselves.”

Morrow said a brutally cold day in Edmonton in early December illustrate­s why such a change is needed. On Dec. 6, Environmen­t Canada issued a wind chill warning when the temperatur­e dipped to -30 C and winds hit 19 km/h, producing a wind chill of -42 C.

Under the current system, no warning would have been issued had the temperatur­e plunged to -42 C and the winds been light, even though the threat of frostbite or hypothermi­a would have been just as high.

Morrow said when the new system is introduced, perhaps as early as in 2014, Canadians will no longer see separate wind chill warnings in Environmen­t Canada forecasts or on its website.

Wind chill and cold temperatur­es will be included together in the Extreme Cold Warnings.
