An ice jam caused Mill Creek in Avoca, Pennsylvania, to flow backwards amid flooding on Tuesday, January 23. At least six homes and a tavern were flooded near the creek, a news report said.
Just before the one minute mark of the video, firefighters can be heard telling people to get off the bridge over the creek. Moments later, the river starts flowing in the opposite direction in a wall of water toward the bridge. Credit: Avoca Fire Department via Storyful
