North Rockies

Small isolated wind slabs may remain on lee slopes near ridgetops

Continue to verify conditions and use normal caution while travelling in avalanche terrain.

Moderate

• We are uncertain due to a limited number of field observations.

No new avalanches have been reported, and human-triggered avalanches remain unlikely. The danger is expected to remain low until Tuesday, when the weather pattern potentially shifts to bring some moderate precipitation to the region.

There have been very limited observations from this area. If you’re heading out, please consider sharing details about the weather and riding conditions through the Mountain Information Network.

A dusting of new snow is covering a widespread crust to mountaintop.

Small wind slabs may be triggerable in isolated leeward areas at upper elevations.

The mid-December facet/crust layer is buried approximately 80 cm deep and is considered unlikely to trigger at this time.

• Periods of low danger may be a good time to increase your exposure.
• Carefully evaluate big and steep terrain features before committing to them.
• Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
