The National Transportation Safety Board announced Sunday that it's sent a team to Alabama to help investigate a fiery multi-vehicle crash that killed 10 people, including nine children.
The big picture: Saturday's crash, south of Montgomery, occurred amid a tropical depression that left 13 people dead in Alabama. It triggered flash floods and tornadoes that razed "dozens of homes" in the Southeast over the weekend, per AP. Parts of the Midwest were also badly hit, including Indiana and Chicago, where a tornado struck late Sunday.
