...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 low to middle elevation rain to 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.

...RIVER RISES AND AN INCREASED RISK OF MUD AND ROCK SLIDES NEXT
WEEK FOR THE CASCADES...
A series of warm, wet, and breezy weather systems will result in
high elevation mountain snow and mid to low elevation rain in the
Washington Cascades next week. Snow levels will fluctuate between
3000 and 5000 feet. Mid to lower elevation snowmelt in addition to
the rainfall 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, snow-free terrain, as well as to recently burned areas and
any burn scars.

...RIVERS RISING IN THE WASHINGTON CASCADES EARLY NEXT WEEK...
A series of weather systems will bring rain and rising river levels
to the area, especially the Washington Cascades, through this
weekend. Another system fed by a strong atmospheric river early next
week will bring heavier rain amounts. Currently a few locations on
the Naches and Yakima Rivers are forecast to reach action stage
starting Tuesday and Wednesday but the chances of reaching minor
flood stage are very low.
