Avalanche Summary

No new avalanches were observed or reported.

Snowpack Summary

Convective spring storms have spread a trace, up to 10cm of new snow through the region. HN sits on a supportive snowpack to mountaintops on all aspects.

There's a strong midpack and dry snow above 2400m on shaded aspects. Solar aspects start as a supportive, hard surface crust that breaks down with strong sun and temps. BTL travel is quite variable but, almost always poor by early PM.
