The National Weather Service in Great Falls has issued a

* Flood Warning for...
snowmelt in...
south central Broadwater County in southwestern Montana...
northern Madison County in southwestern Montana...
southeastern Jefferson County in southwestern Montana...
northwestern Gallatin County in south central Montana...

* until 145 am MDT Monday.

* This includes the Jefferson river near the town of Three Forks
and the surrounding areas.

* Point forecast for the Jefferson river near Three Forks.
    * At 1:00 am Tuesday, the stage was 8.0 feet.
    * Flood stage is 8.0 feet.
    * Minor flooding is occurring... moderate flooding is forecast
      to occur by Thursday... and major flooding is possible by
      Friday night.
    * Forecast... continue to rise to near 9.2 feet by Saturday
      evening.
    * Impacts... at 8.0 feet, farm buildings flood around Three
      Forks. At 8.5 feet, County roads and bridges may have water
      flowing over them. Several homes could flood.

* Water level rises on the Jefferson river will likely accelerate
throughout this week, as warm temperatures help increase snowmelt
out of the mountains. Also, runoff from thunderstorms each day
this week will likely keep other rivers and creeks running high
and fast.

* Water levels could rise even further than what is currently
forecasted, if significant rainfall occurs within the Jefferson
river basin. If you live in this area, we urge you to be
prepared to take immediate action if floodwaters threaten your
life, property, and/or livestock.

* Some locations that will experience flooding include...
Three Forks, Trident, Willow Creek, Cardwell, Lewis And Clark
caverns State Park and Missouri headwaters State Park.

Precautionary/preparedness actions...

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams, country roads, farmland, and other low lying
spots.

Please report flooding to your local law enforcement agency when you
can do so safely.
