New snow, combined with moderate to strong southerly ridgetop winds, will continue to build fresh wind slabs in open terrain, especially near ridgetops.
Light snowfall and strong winds will continue to build wind slabs at upper elevations.
Expect to find wind slabs farther downslope than usual.
New snow, combined with moderate to strong southerly ridgetop winds, will continue to build fresh wind slabs in open terrain, especially near ridgetops.
There were no new avalanches to report on Tuesday and Wednesday. Looking ahead, expect to see reactive wind slabs develop as the a bit new snow falls and the wind picks up.
If you are heading into the backcountry, please share any observations with the Mountain Information Network.
10 to 20 cm of recent snow overlies wind-affected surfaces or old settling storm snow. Recent strong wind has scoured south-exposed slopes and alpine features.
There are a couple of layers of surface hoar/facets or a crust that may be buried 20 to 45 cm deep. These layers have been mostly dormant, but they may become active in isolated areas where a sufficient slab forms overtop.
The remainder of the snowpack is well consolidated.
