Extreme Cold Warning in effect for:

  • Brantford – County of Brant
  • Woodstock – Tillsonburg – Oxford County

A prolonged period of very cold wind chills is expected.

A frigid arctic air mass and strong winds will result in wind chill values of minus 30 to minus 35 tonight through to Friday morning.

Cold arctic air will settle over Southern Ontario tonight. Overnight low temperatures between minus 20 and minus 25 degrees combined with winds gusting between 50 and 70 km/h will result in wind chill values in the range of minus 30 to minus 35.

Conditions should improve Friday as milder air moves into the region.

Extreme cold puts everyone at risk.

Cover up. Frostbite can develop within minutes on exposed skin, especially with wind chill.

If it’s too cold for you to stay outside, it’s too cold for your pet to stay outside.
