Avalanche danger will increase through the day with warming and sun. Conditions will deteriorate sooner than expected if a strong crust does not form overnight. Plan your trip accordingly.

Numerous wet loose avalanches up to size 2 were reported over the weekend.We suspect natural loose wet avalanches will continue on steep, sun-exposed slopes during the afternoons, with a possibility of occasional cornice failures as well. Isolated wind slabs may be primed for human triggering on high north-facing slopes.

Rising freezing levels and strong sun will weaken the snowpack throughout the day.A melt-freeze crust is expected on the surface on all but northerly alpine terrain, where 20 to 40 cm of dry snow sits atop a crust. Some lower elevation areas below treeline may not experience an overnight refreeze and remain moist or isothermal.A weak layer of facets above a hard crust is buried 50 to 70 cm deep. This layer hasn't produced avalanches in over a week.Facets exist at the base of the snowpack in shallow areas.
