A volunteer joins a first responder as they jog toward other ambulances that are gathering outside the Winston Medical Center in Louisville, Miss., Monday, April 28, 2014 after a tornado hit the small hospital, a nursing home next door and a number of homes and businesses in the east Mississippi community. Tornados flattened homes and businesses, flipped trucks over on highways and injured numerous people in Mississippi and Alabama on Monday as a massive, dangerous storm system passed over several states in the South, threatening additional twisters as well as severe thunderstorms, damaging hail and flash floods.
