Pay close attention to avalanche conditions on Sunday. Use extreme caution when choosing routes and making decisions.
New wind slabs are expected to form during the night from Saturday to Sunday. They will be superimposed on old wind slabs that are still reactive. This snow accumulation rests on a melt-freeze crust, providing an excellent sliding surface.
An avalanche was reported to us by a user:
A size 2 avalanche occurred in the forecast zone. It was triggered at a distance of around 50 m by a skier on a convexity. The skier was swept away by the flow. The avalanche was triggered on an east-facing slope at an altitude of around 900 meters.
If you are heading into the backcountry, please share your observations on the Mountain Information Network (MIN).
Between 10 and 15 cm of new snow will be added to an already highly variable snowpack. In alpine zones and at treeline, conditions vary from a frozen surface, to hard ice and rock, to wind-blown snow accumulation.
Below treeline, we find 15 to 25 cm of fresh snow resting on a breakable melt-freeze crust. Below, a layer of light snow (15 to 30 cm) rests on a solid crust formed on March 21. The middle of the snowpack consists of a superposition of well-consolidated snow and melt-freeze crusts.
At higher altitudes, the eastern and southeastern slopes benefit from better snow cover, while the southern, western and northern slopes are rather bald. At mid-mountain, snow depth varies between 60 and 180 cm.
Another storm from Texas will hit us this evening, and precipitation will continue throughout the day on Sunday.
