A fresh influx of arctic air is set to plunge temperatures into the teens (minus 10 degrees Celsius) across the Southeastern U.S., putting residents in Mississippi and Tennessee at higher risk for hypothermia as they approach a sixth day without power. More than 79,000 homes remain dark following a massive storm. Dr. Hans House, an emergency medicine professor, warned against extended exposure to the cold, especially for vulnerable groups like the elderly and infants. National Guard troops have been deployed to the affected regions to deliver essential supplies. Unfortunately, the timeline for restoring power remains unclear as efforts continue amid the ongoing severe winter conditions.
