WATERLOO -- High winds tore a rubber membrane off of the top of part of a John Deere tractor assembly building Thursday afternoon, causing a shift to be canceled today and Friday.
The incident happened Thursday at the John Deere Tractor Plant at 3500 E. Donald St., Waterloo, during a wind advisory affecting Black Hawk County.
The rubber membrane was visibly flapping atop the building from East Donald Street on Thursday afternoon.
The membrane coming loose also caused "a few skylights" to be damaged, said local Deere communications manager Kelly Henderson. She didn't know how many lights were damaged or how long it would take to fix, but said it was "minor."
The incident only affected workers at the 9000 Business Unit, where the John Deere 9R tractors are assembled, Henderson said.
No injuries were reported, and the roof and skylights were being secured and fixed Thursday.
"We shut down that shift, and they'll be off tomorrow," Henderson said of the workers in that unit. She said "essential team members" would be the only ones called in.
Henderson said the roof has never been damaged like that before.
High winds also lefts hundreds of residents across northeast Iowa without power and blew over one semi tractor-trailer on I-380 south of Waterloo on Thursday morning, closing the southbound lanes briefly. The interstate has since reopened.
Another tractor-trailer blew over on Highway 21 south of Schrock Road Thursday afternoon.
