    The deep, persistent weakness remains in the snowpack. This problem appears dormant until the next big warm spell, but we continue to note it's presence.

Weather Forecast

Potentially 15 cm in the higher elevations from this storm system overnight and through the day Saturday. Localized amounts may differ due to convective activity. Temps expected to remain seasonally cold to -6 to -3 with light winds. This precip will likely translate into rain below 1500ms and make it quite wet on low elevation ice climbs.

Snowpack Summary

The new snow will be sitting on a variety of surfaces depending on elevation and aspect. Sun and temperature crusts on solar aspects and lower elevations below 2000ms and expect some sluffing from any steep terrain. Isolated windslabs were reported in the high alpine (3000m) near ridges.

Avalanche Summary

No new avalanches were observed or reported today.

Confidence

Forecast snowfall amounts are uncertain
