Avalanche Summary
No significant avalanche activity has been reported since the last warm, sunny day on Friday (see below). Looking ahead, activity remains unlikely, though sunshine could still trigger cornice collapses or small wet loose avalanches.
Snowpack Summary
Dry snow may linger on high shady north slopes.
The snowpack is generally strong, with a typical spring diurnal pattern: daytime warming moistens the upper snowpack, then overnight cooling usually forms a hard crust at higher elevations. Lower elevations may not refreeze and are melting out quickly.
Dormant weak layers may still exist in isolated alpine terrain, but likely require a very heavy trigger, such as a cornice fall.

Terrain and Travel Advice
- Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
- Pay attention to cornices and give them a wide berth when traveling on or below ridges.
Avalanche Problems
