HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE BILLINGS MT
340 PM MST Fri Dec 16 2016

With the recent cold snap following a very warm Fall, rivers and
streams across the region have rapidly accumulated ice. Normally
this process is gradual and results in little if any impact.
However, with the rapid pace of ice development over the past 10
days there have been reports of several ice jams resulting in low
land flooding. Even large rivers such as the Yellowstone are
clogged with ice at this time.

Until the waterways have a chance to stabilize to this newly
formed ice, the threat of ice jam flooding will persist along
area rivers and streams. This stabilizing process may take a week
or two. Those with interests near rivers and streams should take
precautions to move equipment and livestock to a safe elevation
and monitor the waterway closely for flooding.

Ice jam flooding can create a rapid rise of water with little if
any warning. If you reside in an area that is prone to ice jam or
river flooding please be especially alert over the next week or
two. Please report any flooding to local law enforcement and have
them relay the report to the National Weather Service.
