...RIVER RISES AND INCREASED RISK FOR MUD AND ROCK SLIDES THIS
WEEK...
A series of warm, wet, and breezy weather will bring periods of high
mountain snow and heavy rain to low to middle elevation areas of the
central and southern Idaho Panhandle mountains Monday through
Wednesday. Snow levels will fluctuate between 5000 and 7000 feet.
Lower elevation snowmelt in addition to the rain will lead to rises
on
small creeks and streams. This will also bring an increased risk for
mud and rock slides in areas of steep and susceptible terrain.

ranging from 4,000-5,000 feet north of I-90, to 5,000-7,000 feet
south of I-90, with the highest snow levels across Lemhi County,
