It’s bitterly cold across many parts of the US right now, with temperatures plummeting as low as -38C in certain areas.
The National Weather Service issued wind chill advisories covering a vast area from south Texas all the way to Canada as both countries are getting to grips with dangerously low temperatures.
Here are some photos that show just how bone-chillingly cold it is in the US and Canada.
