Which of the following statements is CORRECT about the tornadoes?

A broad band of severe thunderstorms Sunday sparked heavy rain and hail and prompted tornado warnings from Florida to Virginia, with multiple twisters reported in North Carolina, according to the National Weather Service. At least eight unconfirmed tornadoes were spotted along North Carolina’s 1-85 corridor between Charlotte and Greensboro, with overturned mobile homes, toppled trees and downed power lines left by the storms, the weather service said. Video showed a portion of metal roofing was ripped off an industrial building in Belmont, west of Charlotte, littering nearby trees with clumps of yellow insulation. A video posted on YouTube purportedly showed flashes of snapping power lines as a huge funnel cloud loomed over High Point, North Carolina, near Greensboro. At least 20 homes were reported damaged in the area, the weather service said. High Point emergency management officials were going house to house checking for possible injuries, according to a fire department spokeswoman.
