Snowpack Summary
The Jan 25 surface hoar layer is buried under 5 cm of snow in many areas. While not a problem now, this protected layer of surface hoar will become a weak layer in the future. Strong solar radiation has formed suncrust on south & west facing slopes. The facets at the base of the snowpack remain weak, but theĀ overall snowpack is gaining strength.
Avalanche Summary
No new avalanches observed in the past several days.
Confidence
The weather pattern is stable on Tuesday
Problems
Deep Persistent Slabs
The weak facets at the base of the snowpack have not gone anywhere. But, time and settlement seem to have brought the snowpack into balance. Isolated, large avalanches may still occur, particularly in areas that have not avalanched previously.
Be aware of the potential for full depth avalanches due to deeply buried weak layers.Be aware of thin areas that may propogate to deeper instabilites.
