Extreme Cold Warning

A period of very cold wind chills is expected. Extreme wind chill values of minus 35 or below were reported in some areas this morning.

Extreme Cold Warning in effect for:

Brockville – Prescott
Gananoque – Mallorytown
Merrickville-Wolford – Kemptville
Westport – Charleston Lake
A multi-day episode of very cold wind chills is expected.

2017 is about to end with the coldest air of the year. A fresh surge of record-breaking Arctic air is forecast to encompass the entire province in its icy grip. A trough of low pressure currently over Southern Ontario will drop south of the Great Lakes tonight, opening the door to an even colder northerly wind.

Although winds will be relatively light, the extreme cold is expected to produce windchill values of minus 35 to minus 40 overnight into Sunday, and again Sunday night. New Year’s Eve revellers are cautioned that windchill values will be near minus 35 late Sunday evening as we ring in 2018.

Latest indications continue to show that these very cold conditions will persist into New Year’s Day and potentially Tuesday.

Extreme cold puts everyone at risk.

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

Check on older family, friends and neighbours.

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

Extreme cold warnings are issued when very cold temperatures or wind chill creates an elevated risk to health such as frost bite and hypothermia.
