Avalanche experts: warmer temperatures weaken snowpack

BOZEMAN, Mont. -

We checked avalanche danger across the state and found warmer temperatures are weakening snowpack.

In southwest Montana, avalanche specialists say some mid to low elevation slopes were completely wet yesterday and even though they might be frozen Saturday, deep layers remain weak. 

On upper elevations, they recommend performing stability tests since weak layers still exist beneath the surface.  Danger is rated moderate.

Danger is also rated moderate for west central Montana where warm temperatures have weakened snowpack. Experts say there's a possibility for wet slides on slopes 35 degrees and steeper.

Specialists in the Flathead say they saw wet, loose snow avalanches and wet slab slides during the middle of the week and without freezing temperatures since Tuesday, avalanche danger remains considerable.
