Lo esencial

Carefully assess the bond between the new snow and the underlying crust. New wind slabs are likely to form throughout the day and they likely won't bond well.

    New wind slabs will likely form in exposed terrain on north and east aspectts at treeline and above. These slabs likely won't bond to the new crust.

Confidence

Moderate

Avalanche Summary

Wet loose avalanche activity has likely ended. As fresh snow and wind arrive on Wednesday night, new and likely rider triggerable wind slabs will form over the new crust.

Snowpack Summary

The upper snowpack up to 1400m is moist and saturated from the recent rain. between 1400m and 1600m the moist surface has formed a crust with 10cm of new dry snow above it.

As the freezing level drops this new crust will likely extend down to or below 1000m. at treeline and above new wind slab will form on north and east aspects as the next storm arrives.

Once again terrain below treeline has limited or no coverage.
