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.
Weak overnight recovery may allow the snow to deteriorate rapidly with daytime warming.
Persistent slab avalanches remain possible, especially later in the day as the surface snow deteriorates, and weakens from daytime warming and solar effect.
Wet loose avalanche likelihood will increase throughout the day with daytime warming and sunny conditions, particularly on steep south-facing terrain.
No new recent avalanches were reported.
The widespread, natural avalanche cycle reported over the weekend appears to have ended.
If you go into the backcountry, please submit your observations to the Mountain Information Network.
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. With solar warming expected, anticipate the crust to 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.
