Terrain and Travel Advice
- The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
- Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches
- A crust on the surface will help bind the snow together, but may make for tough travel conditions.
Problems
Loose Wet
The upper snowpack continues to adjust to the recent spring-like weather. Expect small loose wet avalanches to be reactive on steep, solar aspects with sun and warm temperatures.
