Persistent slab avalanches remain possible, especially later in the day as the surface snow deteriorates, and weakens from daytime warming and solar effect.
A widespread surface crust makes for generally safe conditions. Scale back your terrain choice as the surface snow deteriorates and weakens with daytime warming and sunny conditions.

Wet loose avalanche likelihood will increase throughout the day with daytime warming and sunny conditions, particularly on steep south-facing terrain.
No recent avalanche activity has been reported since the widespread avalanche cycle that took place over the weekend.
A melt-freeze crust exists on the surface in most areas. Dry powder snow may still exist on true north-facing slopes in the alpine. Expect the crust to deteriorate, and weaken throughout the day at lower elevations and south-facing slopes.
A layer of weak, faceted crystals over a crust, or surface hoar, remains a lingering concern, buried approximately 40 to 80 cm deep.
