    This layer may increase its reactivity if there is a sudden temperature warming through the day.

Weather Forecast

Unsettled weather, flurries, and seasonal temperatures Tuesday-Friday. Freezing level will be 1000m on Wednesday with a small input of snow and winds. 10cm of snow may accumulate from Monday evening into Thursday morning. Not enough to increase the hazard. 

Snowpack Summary

Warmer temperatures are slowing down the surface facetting and surface hoar process. A Hard mid-pack is providing bridging strength over the weak basal facet layer at tree line and above. Below treeline where the snowpack exceeds 70cm, it has a supportive mid-pack.

Avalanche Summary

No new avalanches reported.

Confidence

Timing, track, or intensity of incoming weather system is uncertain on Wednesday
