Confidence
Moderate
Avalanche Summary
No recent avalanches have been reported in the region. Areas just north of the region have reported small wind slab and wet loose avalanches over the past few days.
Looking forward, wet loose avalanches will become more likely as skies clear and the freezing level rises.
Snowpack Summary
10 to 20 cm of dry snow may be found on north-facing slopes. Surfaces will gradually become wet over the next few days with rising freezing levels and sun exposure.
The facet/crust layer that caused large avalanches in March is buried 100 to 180 cm deep and is unlikely to trigger under the current conditions.
