BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Great Falls MT
321 PM MDT MON MAY 21 2018

The National Weather Service in Great Falls has extended the

* 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 630 PM MDT.

* At 319 PM MDT, Doppler radar indicated thunderstorms producing
  heavy rain across the warned area, including but not limited to
  the headwaters of Beaver Creek. Up to three inches of rain have
  already fallen. Flash flooding has not been reported but may be
  occurring or expected shortly.

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

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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

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.

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

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.
