* WHERE...Portions of south central Montana, including the following
areas, Bighorn Canyon, Pryor/Northern Bighorn Mountains and
Southern Big Horn and north central Wyoming, including the
following areas, Northeast Bighorn Mountains and Sheridan
Foothills.
* WHEN...Through this evening.
* IMPACTS...Excessive runoff may result in flooding of streams and
other low-lying and flood-prone locations close to the foothills.
Some higher foothills roads may become impassable. Any heavy
rainfall over the Elk burn area could result in Flash Flooding and
Debris Flows.
* ADDITIONAL DETAILS...
- Heavy rainfall fell just off the snowpack last evening with
half an inch to an inch of precipitation reported along the
I-90 corridor. Temperatures are beginning to cool over the
higher terrain turning rain to snow over the higher
foothills. This will limit the higher end impact potential
that was previously anticipated. However, there remains the
threat of at least minor flooding in the foothills due to
heavy rain that fell earlier tonight combined with continued
light to moderate rainfall that is forecast through this
morning.
