Avalanche Summary
No new avalanches have been reported, but observations are extremely limited. Consider sharing what you see on the Mountain Information Network if you go into the backcountry:
How much new snow?
Was it wind-affected?
What are surface conditions like?
Snowpack Summary
Upper elevations may have received 10 to 20 cm of new snow, as mixed precipitation was observed at highway passes on Sunday. This snow likely sits on top of melt-freeze crusts.
A typical spring diurnal pattern is in effect. Daytime warming moistens the upper snowpack, and overnight cooling usually forms a hard crust at higher elevations. Lower elevations may not refreeze and are melting out quickly.

Terrain and Travel Advice
- Carefully evaluate steep lines for wind slabs.
- Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
