A significant amount of new snow and rain are causing dangerous avalanche conditions.
Reduce your exposure to overhead hazard and stay away from run-out zones.
A buried layer of facets in the snowpack is expected to be more reactive in wind-affected thin rocky terrain features. Triggering of this layer is less likely where a supportive crust is present above.
Moderate to heavy precipitation and strong southerly winds will build reactive storm slabs on Monday.
Rain and warm temperatures are destabilizing the recent snow. Wet loose avalanches will remain possible as long as temperatures stay above zero degrees or it's raining.
No new avalanches have been reported in the past few days.
If you head out in the backcountry, let us know what you're seeing by submitting a MIN report.
Up to 60 cm of new snow will have fallen above 1400 m by Tuesday morning, accompanied by strong southerly winds. This new snow is falling on surface hoar and faceted snow from recent cold temperatures.
Below this, a layer of facets from early February and a thick crust from late January are at a similar depth between 80 and 120 cm below the snow surface. These layers remain possible to trigger with large loads and are most likely to be found on north-facing slopes.
