Another metre of snow is expected to fall on the parts of north-eastern America that have been covered by a huge storm.

Some areas have already been hit by up to 1.5 metres of snow thanks to a massive snowstorm that has unusually seen all 50 US states experience sub zero temperatures.

People have been trapped in their homes and cars, schools have been closed, and travel has been disrupted. At least eight people have died in the state of New York.

The freezing weather has been caused by cold air moving southwards.

But conditions are set to get warmer by the weekend.
