NASHVILLE — About 240 million people were under cold weather advisories and winter storm warnings Saturday as a powerful system threatened to bring howling winds, flooding and heavy snow to the East Coast — including blizzard-like conditions stemming from a ''bomb cyclone'' in the Southeast, a forecaster said.
Temperatures were plummeting even as tens of thousands of homes and businesses remained without power from a blast of snow and ice last weekend that snarled traffic, knocked down trees, and caused more than 100 deaths. A low temperature of minus 27 degrees Fahrenheit (minus 33 degrees Celsius) was recorded Saturday morning in West Virginia, said Bob Oravec, lead meteorologist for the National Weather Service in College Park, Maryland.
Parts of the southern Appalachians, the Carolinas and Georgia could see 6 to 10 inches (15 to 25 centimeters) of snow, he said. The Carolinas could see blizzard conditions stemming from the bomb cyclone, a term Oravec used to described an intense, rapidly strengthening storm system off the Southeast coast packing strong winds.
''Anytime you have cold weather advisories or extreme cold warnings, it is dangerous to be outside. Frostbite can occur,'' Oravec said. ''Especially in areas that have or are experiencing power issues still, prolonged exposure to cold weather is not good for yourself.''
In Myrtle Beach, South Carolina — whose official seal is the sun, palm trees and a seagull — 6 inches (15 centimeters) of snow was expected. The city has no snow removal equipment, and authorities planned to ''use what we can find,'' Mayor Mark Kruea said.
Subfreezing weather was forecast into February, with heavy snow in the Carolinas, Virginia and northeast Georgia over the weekend including up to a foot (30 centimeters) in parts of North Carolina. Snow was also said to be possible from Maryland to Maine.
The frigid cold was expected to plunge as far south as Florida.
Temperatures neared the teens (minus 10 Celsius) in Nashville, Tennessee, and frustrations bubbled up for those who spent a week without power.
