Kernpunkte

If temperatures remain warm, rain soaked wet slabs releasing on crust layers are still possible.

Moderate - Due to the number of field observations

Avalanche Summary

No new avalanches were reported in this region on Monday. However, there are currently very few professional observers submitting daily observations. Please submit your observations to the MIN. Photos of avalanches or current conditions are particularly useful.

On Saturday, natural and skier triggered loose wet avalanches to size 1.5 were reported on all aspects at treeline and above.

Snowpack Summary

Rain to mountain-tops Thursday night soaked 20-40 cm of recent snow and initiated a loose wet avalanche cycle at treeline and above on Friday. Below treeline, the snow is isothermal (0 C throughout the snowpack) and disappearing rapidly.

As temperatures cool, we will enter a diurnal cycle during which the hazard will be low in the mornings, if there was a strong overnight freeze, and elevate throughout the day depending on warming and solar radiation. Hazard ratings are for the peak hazard expected during each day.
