...FLOOD WATCH REMAINS IN EFFECT THROUGH THIS AFTERNOON...

* WHAT...Flooding caused by excessive rainfall is possible, along
  with flash flooding over recent burn scars.

* WHERE...Southeast Montana and Sheridan County Wyoming.

* WHEN...Through this afternoon.

* IMPACTS...Excessive runoff may result in flooding of creeks and
  other low-lying and flood-prone locations. Flooding may occur in
  poor drainage and urban areas. The risk of flooding will diminish
  late this afternoon and evening as showers taper off.

* ADDITIONAL DETAILS...
  - The heaviest rainfall is slowly shifting eastward to southeast
    Montana and northeast Wyoming.
  - The Elk and McGhee-Remington burn scars are particularly
    vulnerable to flash flooding and debris flows. Any other burn
    scars from this summer will have elevated flash flood potential
    as well.
