An ice jam is when a river freezes, then warms up just enough to break up the ice into chunks. The chunks flow downriver until they crash into solid ice, or a bridge, or come to a narrowing of the river. There, the ice builds up and causes flooding. Melting snow and ice from surrounding areas also feed into the flooding. Recent winter weather has caused ice jams all over the eastern US. The home above was flooded by Pine Kill Stream in Sullivan County, New York. The residents were evacuated safely.
