* Big Horn emergency management reported 2 ice jams along the Big
  Horn River that may still affect homes and property. One ice jam
  is between Basin and Greybull and the other is downstream of
  Greybull near the Sheep Mountain area. Only minor flooding has
  been reported with these ice jams.

* Greybull emergency management reported that 2 ice jams are still
  located upstream and downstream of the town. The river has
  continued to recede and is within it banks. Water is running below
  the jams. The main channel at the highway bridge is open with free
  flowing water.

* Colder temperatures in the next few days should hinder any
  significant movement of ice along the Big Horn River from Basin to
  Greybull.

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.
