Watch for the crust breaking down with strong sun and warm days.
The search for dry snow may draw you to north facing alpine terrain, be aware buried weak layers may remain reactive here.
Uncertainty remains on how quickly these slabs will gain strength with cooler temperatures. Triggering is thought to be most likely on north facing alpine features. 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 Thursday. Widespread wet avalanche activity occurred previously during the warmer temperatures (photo below).
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 go into the backcountry, please submit your observations to the Mountain Information Network.
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 approximately 30 to 60 cm deep.
