The death toll from powerful winter storms in the central and eastern United States has risen to at least 14, officials said Monday, after floods, gale-force winds and bitterly cold temperatures swept the region. The National Weather Service (NWS) warned on Monday of a winter storm system carrying arctic air that would cause “record cold,” with wind chill expected to hit as low as -60 degrees Fahrenheit (-51 degrees Celsius) in Montana and North Dakota. “I’ve got more tough news. The death toll in Kentucky has now risen to 12,” said Kentucky Governor Andy Beshear in a social media post on Monday, raising the toll from eight a day earlier. West Virginia Governor Patrick Morrisey said on Monday his state had also seen at least one death from the weather. “We have one confirmed fatality at this time,” he told a press briefing, warning that further flooding was expected. “There are still several people who are missing.” In addition, one person died in the southern city of Atlanta, Georgia. The victim was killed when an “extremely large” tree fell on his house early Sunday, fire official Scott Powell told local media. Most of the dead in Kentucky, Beshear said in an earlier news conference, drowned when trapped in their vehicles by fast-rising floodwaters.
