LOUISVILLE, Ky. (AP) — The U.S. Coast Guard is warning of rough conditions on the Ohio River because of high water.

Higher than usual water levels have created stronger currents, the Guard said in a news release Monday.

The Guard said debris, rip currents and eddies are showing up in areas along the river where they don’t normally occur.

“We urge mariners to be cautious and properly prepared before getting underway to ensure safe travel along the waterways,” said Capt. Eric Carrero, a Coast Guard official in New Orleans.

The Coast Guard received reports of ships striking fixed objects, called allisions, over the weekend. No injuries or spills from the incidents had been reported, the Coast Guard said.

The allisions were observed in Louisville, Kentucky; Racine, Ohio and Parkersburg, West Virginia.
