Deadly storms are again barrelling down on the southern US, a night after tornadoes claimed 16 lives.
Seven deaths were reported in Alabama and one in Mississippi after twisters struck on Monday evening, although not all these fatalities were confirmed.
Matt Coker, a storm chaser, told the BBC that he was tracking the tornado yesterday when it hit the town of Mayflower in Arkansas.
