Jack Frost has popped up on the radar to being the new year.

Temperatures are dipping into the low minus 30's and high 40's factoring in the wind chill.

Emergency Preparedness Meteorologist with Environment Canada, John-Paul Cragg says that cold temperatures could linger for a while.

"Potentially staying cold for the second week of January as well," he explained. "Most models are showing that cold sticking around. The first two weeks of January are looking like they are going to be quite cold."

Cragg adds that when temperatures are this low, layers are vital, with frost bite ready to attack within minutes.

"The most important thing when you're outside with these temperatures is to dress warm. Make sure you're staying dry, you have your toque on and your mitts. Temperatures like this, you can cool down very quickly."

He notes that if you are testing the arctic air, it is also key to know when you or someone you are with must get inside.

"It's important that if you're outside, to make sure that you know the signs for hypothermia. Shivering, confusion, loss of muscular control, difficulty walking," said Cragg. "If you're feeling any of these things, it is very important to get inside and get warm as quickly as possible."

In addition to being outdoor ready, it is also a good idea to pack extra clothing or blankets when travelling, in the event of unforeseen circumstances.
