Southern US braced for rare winter storm - as LA warned of further fires Large parts of the southern US are braced for a rare winter storm expected to bring below-freezing temperatures, heavy snow, and freezing rain and sleet, forecasters have said.
Around 21 million people are under a winter storm warning, Mr Chenard added, while about 170 million people in an area from the Rockies eastward are under either an extreme warning or a cold weather advisory.
Millions of people, primarily across the southern US and mostly living in an area from Texas to Florida, are facing some type of weather hazard, NWS meteorologist Marc Chenard said.
Between three and seven inches of snow (7.5cm to 15cm) is set to fall over parts of southern Mississippi and southeast Louisiana, including New Orleans, heading into Tuesday, the NWS said.
More than 55 million people in the Gulf Coast region could be affected, Sky News' US partner, NBC News, has reported.
