941 AM MST FRI FEB 24 2017

The National Weather Service in Riverton has issued a

* Hydrologic Advisory for...
  An Ice Jam in...
  Central Big Horn County in central Wyoming...

* Until 930 AM MST Saturday

* At 926 AM MST, Big Horn County emergency management reported there
  were still 2 large ice jams along the Big Horn River that may
  cause additional flooding. One ice jam was between Basin and
  Greybull. This ice jam has moved downstream about an half mile
  since Thursday night.  The other major ice jam is located
  downstream of Greybull near the Sheep Mountain area and on Georgia
  Pacific property. No major movement or changes have been
  reported with that ice jam.

* There are also 2 smaller ice jams that are just upstream and
  downstream of Greybull. These jams are not causing any significant
  flooding in and around Greybull.

* Colder temperatures through early next week should inhibit any
  significant movement of current ice jams. There also should be no
  significant additional ice accumulation on the Big Horn River with
  the expected temperatures through early next week.

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.
