Triggering slab avalanches in the alpine remains possible, especially on steep or convex slopes.
Avoid steep, rocky, and wind affected areas where triggering slabs is more likely.

Avalanche Summary
A naturally triggered size 2.5 persistent slab avalanche was reported on an east aspect in the alpine on Saturday. The slab failed on the crust below the most recent storm snow. It was in steep, rocky, wind affected terrain below an alpine ridgetop.
Additionally, numerous naturally triggered wet loose avalanches up to size 2.5 were reported on sunny aspects.
Snowpack Summary
High freezing levels and strong solar radiation have created moist snow on all aspects and elevations.
Up to 40 cm of recent snow has settled rapidly with intense solar radiation and warm temperatures.
Lingering slabs may still be reactive in the alpine, especially on steep or convex terrain features.
A series of crusts exist in the upper snowpack.
Expect difficult travel at lower elevations with thin snow coverage.

Terrain and Travel Advice
- Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
- Be alert to conditions that change with aspect and elevation.
- Remote triggering is a concern, watch out for adjacent and overhead slopes.
- Minimize exposure to sun-exposed slopes when the solar radiation is strong.
