A winter storm that hit the Southeast over the weekend killed at least one motorist, left more than 300,000 customers without power, and forced the cancellation of over 1,000 flights, Reuters reports. A weather warning is still in effect for most of North Carolina, Virginia, and southern West Virginia as at least an additional two inches of snow were expected to fall overnight and into Monday, adding to the foot of snow that fell over the weekend. Around 310,000 people were without power in the Carolinas, Tennessee, and Virginia on Sunday evening. The severe weather also caused over 1,000 flight cancellations at Charlotte/Douglas International Airport in Charlotte, North Carolina. An 18-wheeler was found in a river in Kinston, North Carolina, on Sunday morning, WRAL-TV reported, and the driver has not yet been found. Another driver was confirmed to have been killed outside of Charlotte when a tree fell on a car.
