HUNTSVILLE, Ala. (AP) — A 5-year-old was killed when strong winds blew over a row of tents at an Alabama air show during storms that stretched across the South on Sunday while severe weather caused airport delays in the East, officials said.

The winds that toppled the tents and canceled the air show in Huntsville came during an isolated strong thunderstorm that developed just west of the airport with gusts of 48 mph, said Tim Troutman of the National Weather Service.

Witnesses told The Huntsville Times that a generator fell on the child Sunday. The death was confirmed by the Madison County coroner's office.
