Areal Flood Warning

Statement as of 10:38 AM MST on January 03, 2010

The National Weather Service in Great Falls has extended the Flood Warning for... locations along the Gallatin river in southwest Montana - - -
* until the ice jam breaks on the Gallatin river
* at 1030 am MST the Gallatin river remained over it banks due
to a major ice jam near Big Sky... including areas along Highway 191 at Rainbow ranch Road. Little change has occurred in the overall level of flooding and ice buildup along the river over the last 24 hours.
* Impacts... when the ice jam breaks... there is the potential for a significant amount of water to rush down the Gallatin river quickly... causing more flooding problems downstream. Additionally... there is the potential that damage could occur
along the shoreline and to bridges crossing the Gallatin river... from ice and other debris washing down the river.
.. Anyone who lives along the Gallatin river from Three Forks to Big Sky should be prepared to move quickly should flooding occur.
.. Anyone who plans recreation activity on the Gallatin river should be prepared for possible ice or debris flow... when the ice jam breaks.
.. A Flood Warning means that flooding is imminent or has been reported. All interested parties should take necessary precautions immediately.

Precautionary/preparedness actions.

Most flood deaths occur in automobiles. Never drive your vehicle into areas where the water covers the roadway. Flood waters are usually deeper than they appear. Just one foot of flowing water is powerful enough to sweep vehicles off the Road. When encountering flooded roads make the smart choice... turn around... dont drown.
