Back off sun affected slopes as snow becomes wet and slushy.
While dry snow may remain on north facing alpine features, weak layers are possible to trigger here.
Triggering remains possible at higher elevations, with greatest concern for north facing alpine slopes. Minimize your exposure here.
The potential for wet avalanches will increase throughout the day with warm and sunny conditions, particularly on steep south-facing terrain. Avoid sun affected terrain as the surface crust breaks down.
No new avalanches were reported on Friday. Widespread wet avalanche activity occurred previously during the warmer temperatures (photo below). Smaller wet avalanches may continue with sunshine and warm temperatures.
Whumpfs (a collapse of the buried weak layer), and test results still indicate that triggering the persistent weak layer is possible in specific features.
If you head into the backcountry, please submit your observations or photos to the MIN.
A thick melt-freeze crust sits on the surface in most areas, except for high north-facing alpine slopes where dry snow may still exist. This crust may soften throughout the day at lower elevations and south-facing slopes. At lower elevations, the snow below the crust is likely moist or wet to ground.
A layer of weak, faceted crystals overlying a crust, remains a lingering concern for human triggering at upper elevations, buried 30-60 cm deep.
