with significant snowfall and high wind.
* WHERE...The mountains around Seeley Lake, the Rattlesnake, and the
Bitterroot Mountains from Lolo Pass to Lost Trail Pass.

become overloaded by the new snow and wind.
* PRECAUTIONARY / PREPAREDNESS ACTIONS...Exceptionally dangerous avalanche
conditions may develop. Travel in avalanche terrain is not recommended.
Avalanches may run long distances and can run into mature forests, valley
floors, or flat terrain.

...AN ATMOSPHERIC RIVER PRODUCING MODERATE TO HEAVY PRECIPITATION
WILL INCREASE THE RISK FOR ROCK AND LANDSLIDES, ALONG WITH RISING
CREEKS AND RIVERS...
Idaho and Clearwater Counties
A prolonged Atmospheric River is expected to impact north central

The most likely rainfall scenario forecasts 1.25 to 2.75 inches for
the valleys of Idaho and Clearwater counties in north central Idaho,
and 3.00 to 5.00 inches expected in the mountains, but precipitation
will be mainly in the form of snow of 2 to 6 feet.
The rainfall will increase the risk of rock and landslides across
north central Idaho. Continue to monitor the latest forecast updates
as this system approaches.
