Successive storms will result in elevated danger, particularly in exposed, windy locations. There's a chance it may start to snow heavily a little earlier than expected on Wednesday. If so, adjust your objectives accordingly.
Confidence
Moderate - Timing of incoming weather systems is uncertain
Weather Forecast

Avalanche Summary
Natural avalanches were reported up to size 2.5 on Sunday. Activity diminished on Monday following a drying and cooling trend, but is likely to pick up again, especially in steep, wind affected terrain for Tuesday.
Snowpack Summary
Approximately 20-30 cm new snow now sits on top of a rain crust (or multiple crusts) that formed during the recent wet weather. Strong winds have blown snow around in exposed areas creating drifts and scoured areas. Snowpack depths are typically around 140 cm in sheltered treeline locations, although deeper (and shallower) spots certainly exist on account of the strong winds.
Problems
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
