The extreme cold warning continues Sunday for northern New Brunswick.
In its release, Environment Canada said the wind chill will make it feel as cold as -35 C this morning.
"A period of very cold wind chills is expected," the national weather service said.
Environment Canada said extreme cold warnings are issued when very cold temperatures or wind chill creates an elevated risk to health such as frost bite and hypothermia.
The warning reminds people to wear appropriate clothing for the weather, dress in layers, wear warm socks, gloves, a hat and scarf in cold weather.
In other parts of the province there is a chance of flurries this afternoon. Temperatures are -15 C, and feel like -28 C to -30 C with the wind chill.
