The National Weather Service says it was probably an EF-0 or EF-1 tornado thattore through Churchill Downs last night, damaging more than a dozen barns and other backside buildings, packing winds of up to 120miles per hour. Spokesman John Asher calls it a miracle that no humans or none of the 1,400 thoroughbreds stabled at the track suffered injuries."It really is more remarkable by the moment when you walk through and look at the damage, see the scope of the damage, and to see what occurred that there were no serious injuries. We had no reports ofnot only serious injuries but no injuries whatsoever," he said.Asher says track workers and horses whose dwellings were damaged are being relocated.Live racing and training today were cancelled. Asher says Friday’s night racing card will go off as scheduled. There are two weeks left in the Churchill Downs spring meet.(Photo courtesy of Churchill Downs)
