About 150m faced cold weather advisories along eastern US, and two in North Carolina died in storm-related conditions

A bomb cyclone produced freezing temperatures across a large portion of the US from the Gulf coast to New England, bringing heavy snow to North Carolina where two were killed in storm-related conditions, and setting records in Florida, where officials warned of ice and falling iguanas.

About 150 million people were under cold weather advisories and extreme cold warnings in the eastern portion of the US, with wind chills near zero to single digits in the south and the coldest air mass seen in south Florida since December 1989, said Peter Mullinax, a meteorologist with the weather prediction center in College Park, Maryland.
