Officials at Churchill Downs–home of the Kentucky Derby–have revised the number of horses displaced by the June 22 tornado that damaged nine barns at the Louisville, Ky., track, estimating that between 75 and 100 were relocated as a result of the storm’s damage.

Churchill officials initially estimated as many as 150 to 200 horses were removed from the damaged barns, but adjusted the number late in the day on June 23 as they continued to assess the full extent of the damage from the storm that hit with little warning shortly after 8 p.m. EDT on June 22. Thirty of the displaced horses were relocated to Keeneland Race Course in Lexington, Ky., some were moved to other areas within the Churchill stable area, and others went to private farms or training centers.

Additionally, Churchill reported that 6 1/2 of the nine damaged barns have been declared uninhabitable by fire department officials.

In a press release Churchill said Joe Sullivan of the National Weather Service (NWS) office in Louisville toured the stable area June 24 and confirmed that the damage was inflicted by a tornado that packed top winds of 105 miles per hour as it roared through the Churchill stable area and was rated as an F1 storm on the Fujita Scale, the official classification system for tornado damage
