A huge winter storm is set to bring the coldest Christmas in four decades to parts of the US, with the mercury set to plummet to a bone-chilling -45C.
Nicknamed Winter Storm Elliot by the Weather Channel, alerts have been put out across 37 states - home to 92 million people - to prepare people for the sub-zero temperatures.
It has been dubbed a “kitchen sink” as it will throw not only freezing conditions at people but also snow, high winds and even heavy rain.
