Ice jams on rivers and streams possible this week... Seasonably mild temperatures this week will cause areas of ice to break up on rivers and try to move downstream. This may lead to ice jam flooding if ice gets piled up along river channels. One particular area we are watching closely is in Yellowstone County. This is from the confluence of the Clarks Fork and Yellowstone Rivers near Laurel, downstream to Duck Creek Bridge south of Billings. Water levels are approaching bank level in a few locations along this stretch as ice piles up and could result in some minor flooding this week. Those living near waterways over the region should pay close attention to the state of the ice this week. Move livestock and equipment away from low lying areas, and be prepared to seek higher ground should waters rise. If ice jam flooding is observed, please report it to local law enforcement, and have them pass it on to the National Weather Service.
