Snow and storms across US as 55 reported killed in winter weather

Cold snap continues from south to Pacific north-west, with thaw not expected until next week

The deep freeze affecting millions of people across the US is continuing this weekend, as bitterly frigid air spilled into the midwest from Canada amid high winds that could make it feel like -30F (-34C) outside in some areas.

The list of severe weather events was growing as the US struggled with the intense cold and news reports said at least 55 people across 10 states had been killed in weather-related incidents over the past week or so since the cold snap hit.
