Avalanche Summary

Expect an increase in avalanche activity with continued snowfall accumulating Monday night through into Tuesday combined with moderate to strong wind and warming temperatures.

Snowpack Summary

10-25cm of new snow has buried previously formed windslabs, facets and surface hoar. Moderate to strong winds have loaded leeward features with new touchy wind slabs. A widespread crust that was buried in November is typically down 80-100cm. Recent tests show variable results with this persistent weakness. Some show results as hard and resistant and other show it may have the propensity to propagate large avalanches if triggered from thin rocky areas.
