Flash Flood Warning
National Weather Service Great Falls MT
1237 PM MDT MON MAY 21 2018

The National Weather Service in Great Falls has issued a

* Flash Flood Warning for...
  West central Blaine County in north central Montana...
  Southeastern Hill County in north central Montana...
  Northeastern Chouteau County in north central Montana...

* Until 330 PM MDT.

* At 1233 PM MDT, Doppler radar indicated stationary thunderstorms
  producing heavy rain across the warned area. Up to 1.5 inches of
  rain has already fallen. Flash flooding is expected to begin

Excessive rainfall over the burn scar may result in debris flow
moving through the upper drainages of the Bears Paw Mountains,
including Beaver Creek. The debris flow can consist of rock, mud,
vegetation and other loose materials.

Additional rainfall amounts of 1 to 3 inches are possible in the
warned area.


Move away from recently burned areas. Life-threatening flooding of
creeks, roads and normally dry arroyos is likely. The heavy rains
will likely trigger rockslides, mudslides and debris flows in steep
terrain, especially in and around these areas.

A Flash Flood Warning means that flooding is imminent or occurring.
If you are in the warned area move to higher ground immediately.
Residents living along streams and creeks should take immediate
precautions to protect life and property.
