Summary

Weather Forecast

Minimal re-freeze Saturday night at valley bottom. Freezing levels Sunday are expected to reach 2200m with valley bottom high temps near +8. Light precipe with minimal accumulation and moderate to strong winds are forecasted Sunday. The possibility of solar inputs could deteriorate the snowpack structure at lower elevations quickly.

Snowpack Summary

Surface melt freeze crusts extend high into the alpine on solar aspects. On shady aspects, 10cm of snow from Thursday AM is well settled. Several persistent layers are buried in the snowpack, consisting of crusts and/or facets. These are currently unreactive but may wake up in the future as spring heat starts to penetrate deeper in the snowpack.

Avalanche Summary

No new avalanche observations Saturday. Forecast team observed more evidence of last Wednesdays avalanche cycle.
