PRECAUTIONARY/PREPAREDNESS ACTIONS...

River ice is very unpredictable, and may move and jam with little
notice. Any ice jam can cause flooding, as the ice dams the river,
causing rapid increases in river levels in a short period of time.
People living near the Big Horn River should monitor the situation
closely and be ready to move to higher ground if flooding occurs.
