Lingering wind slabs may still be reactive on lee features below alpine ridgetops.
Avoid steep, rocky, and wind affected areas where triggering slabs is more likely.
Summary
Confidence
High
Avalanche Summary
Numerous naturally triggered wet loose avalanches up to size 2 were reported on sunny aspects on Friday.
Several natural and rider triggered wind slabs up to size 1.5 were also reported on northerly aspects in the alpine.
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 wind slabs may still be reactive on lee features below alpine ridgetops.
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.
- Back off slopes as the surface becomes moist or wet with rising temperatures.
- The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
- Pay attention to cornices and give them a wide berth when traveling on or below ridges.
