The U.S. Coast Guard canceled plans for an ice-breaking operation Monday in the area of the Buffalo Outer Harbor and the southern approach channel to the Port of Buffalo, officials said.

Lt. Adrian Palomeque explained that there was too much “brash ice” – ice formations that can be sharp – in the area. He said that the Coast Guard Cutter Neah Bay and Canadian Coast Guard Ship Griffon encountered heavy brash ice that was five-feet in thick some locations, making ice-clearing nearly impossible.

The ships were trying to clear the way for a commercial vessel, the Algoma Enterprise.
