upstream of the Highway bridge. The ice is thinning considerably
along the Main Channel upstream and downstream of the Highway
bridge. Emergency management also reported that the Main Channel
is open with flowing water along the Big Horn river at basin. Ice
jams are occurring downstream between basin and Greybull.

* The stage at the Big Horn river at Greybull at 12 PM this

around 91.0 feet through Thursday morning. Flood stage at the Big
Horn river is at 92.0 feet.

* Much cooler temperatures are expected by Thursday and Friday which
should decrease the number of ice jams along the Big Horn river
from downstream of 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.
