The natural cycle from the last two days is tapering off. However, remain vigilant in your terrain and route choices.

Summary

Weather Forecast

Expect light cloud cover and temps between -2 and -8 with no precip until Tues, at which time an increase in wind from the west with rising temperatures will become inputs that raise the danger rating.

Snowpack Summary

15-25cm of storm snow sit on top of the Jan 4th layer. Wind-slabs as thick as 60cm can be found in high elevation lee areas. Below the Jan 4th layer there is weak faceted snow in the upper snowpack and while the mid and lower pack are supportive in thick areas, thin areas are faceted out completely.

Avalanche Summary

While no new avalanches were observed or reported today, expect to see evidence of the avalanche cycle from the last 2 days.

  • Good group management is essential to manage current conditions safely.
  • On steep slopes, pull over periodically or cut into a new line to manage sluffing.

Aspects: All aspects.

Elevations: All elevations.
