Hail and rain hammered the Phoenix-area Friday, but it was the wind that caused the biggest headache for festival organizers.
The gusts were so strong it sent tents flying everywhere.
Vendors desperately tried to keep their displays together as visitors dodged the flying objects.
The weather forced organizers to shut down the carnival rides and evacuate some of the larger tents for a couple of hours.
Up to 25-millimetres of rain fell in the region as a late winter storm crossed over Arizona.
The storm also knocked out power for thousands near Phoenix.
The Ostrich Festival is in its 25th year and celebrates the city of Chandler's long history of Ostrich ranching.
