A storm starting Thursday will likely increase the avalanche danger over the next few days.
Previous strong SW winds have created wind slabs in alpine. Forecast winds and snow will increase the size and likelihood of triggering, and slabs may start to form at treeline.
A storm will enter the region Thursday. Expect increasing winds over the day from the W/SW, 5-10cm by the end of the day, and temperatures around -15C at treeline by midday. Friday may see 10-15cm more, continued winds, and temperatures around -5C to -10C.
Up to 20cm storm snow from a few days ago was distributed into alpine wind slabs wind slabs which sit over facets from last weeks cold snap in some locations. 80-110cm sits over the Dec 2 crust and facets in this area, but as of yet this has not been active. 200-260cm on average at treeline.
No avalanches observed or reported Wednesday.
