Avalanche Forecast

A widespread natural avalanche cycle occurred in the past few days as rain impacted the snowpack. Numerous large (size 2-3) wet slab avalanches have been reported from all aspects and elevations.

If poor riding quality doesn't deter you on Tuesday, keep in mind that human-triggered avalanches remain likely. Avoid overhead exposure, large natural avalanches have the potential to entrain significant mass and run to valley bottom.

Rain has created a moist or wet upper snowpack at all elevations. A weak surface crust may have formed overnight at upper elevations.

Roughly 40 to 50 cm of snow from last week sits over various old surfaces. In some areas, it is slow to bond due to sugary facets.

Near the bottom of the snowpack, there are a series of crusts and facets that are more prominent in shallow areas.

• Make conservative terrain choices and avoid overhead hazard.
• Keep in mind that wet avalanches can be destructive due to their high density.
• The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
