Be aware that stubborn wind slabs are present in the Alpine and in open Treeline features.
With limited early season options to ride, overcrowding is an issue. Avoid putting yourself below other groups, and if you are above a party, communicate with them and avoid dumping an avalanche on top of them.

Avalanche Summary
Avalanche activity has decreased over the last 36hrs, with no new avalanche activity observed in the highway corridor.
A few dry/loose avalanches to sz 1-1.5 were noted from steep N-facing aspects on Cheops.
Snowpack Summary
50cms of snow fell over the weekend. On solar aspects, this new snow sits on a rain crust up to 2300m and a suncrust at higher elevations. Wind redistribution at Alpine/Treeline elevations has created a soft slab on open slopes and lee features. A thick crust can be found 20-30cm off of the ground. Below Treeline, the snowpack tapers to 40cms or less, making ski outs treacherous! Expect glaciers to have poor coverage and thin bridging.
Weather Summary
Small storm pulses will move through the Pass Wed and Fri, with a gradual warming trend into the weekend.
Tues Night: Cloudy, Alp low -11*C, light SE winds.
Wed: Flurries, 5-10cm, Alp high -6*C, light/gusting mod SE winds, freezing level (FZL) 1200m
Thurs: Cloudy with sunny periods, trace snow, Alp high -6*C, light SE winds, 1300m FZL
Fri: Flurries, 10-15cm, Alp high -3*C, light E winds, 1400m FZL
Terrain and Travel Advice
- Be alert to conditions that change with elevation, aspect, and exposure to wind.
Problems
Wind Slabs
Winds from the weekend created surface slabs in open Treeline and Alpine features. These slabs may be reactive at ridge top, in lee features, or in areas where they overlie a crust.
Aspects: All aspects.
