Environment Canada has issued extreme cold warnings for all of New Brunswick and Nova Scotia.
The weather agency said an arctic airmass will combine with strong northwest winds Friday, causing “bitterly cold conditions.”
In New Brunswick, wind chill values of -35 to -45 C are expected to develop Friday, persisting into Saturday morning before beginning to moderate Saturday afternoon as winds subside.
Nova Scotia is expecting wind chill values of -35 to -43 C over the same time period.
Extreme cold warnings are issued when cold temperatures and wind chill creates “an elevated risk to health such as frostbite and hypothermia.”
The weather alert warned that people should cover up as frostbite can develop on exposed skin within minutes.
