    The significance of this problem will vary widely depending on aspect, elevation, and the time of day. Pay attention to how good the overnight freeze is, as well as how quickly things are warming up.

Weather Forecast

Rising freezing levels, poor over night recovery, and light precip are in store for the weekend. Moderate to strong winds are also forecast for the alpine.

Snowpack Summary

0-10cm low density new snow, redistributed by strong SW winds, overlies a sun crust at all elevations and a melt-freeze crust up to 2100m on all aspects

Snow pack below 1700m is either wet or refrozen depending on the time of day and the solar input.

Avalanche Summary

The widespread wet loose avalanche cycle has tapered off thanks to good overnight freezes and colder temps. A few wind slabs up to size 1.5 have been noted in the alpine.
