New snowfall combined with rising temperatures will elevate danger levels.
A sharp increase in hazard is expected when precipitation changes from snow to rain.
Expect new snowfall and warming temperatures to create a storm slab problem. This new slab will overlie a variety of surfaces, including a thin sun crust on solar aspects and smooth, hard wind-pressed snow in wind-exposed areas.
No avalanches have been reported. However, observations are limited.
If you're heading out into the backcountry, please consider sharing your observations on the MIN.
Above treeline, an estimated 20 to 30 cm of snow sits on a thick crust that extends to the ground. The snowpack is around 40 to 70 cm deep in the alpine, and shrinks rapidly below treeline.
In wind exposed areas, soft snow has likely been redistributed into lee features.
