According to the National Weather Service, ice jam flooding is expected to continue on the Big Horn River at Worland through today. River levels are expected to continue to fall Monday through today.

Forecasters with The National Weather Service are predicting continued flooding of the Big Horn River through early Tuesday [today] as the result of river ice jams between Worland and Greybull, said Chris Jones, NWS meteorologist in charge in Riverton.
“Generally dry conditions are being forecast until Thursday, Jones said. “Warming temperatures after Wednesday could cause further flooding/ice jam issues in these areas into this upcoming weekend.”
