Avalanches are possible at upper elevations where dry new snow fell.
Travelling conditions are tricky where a thick surface crust is present.
Continually assess conditions as you travel.
New snow is found at upper elevations. While amounts are uncertain, newly formed wind slabs may exist on wind-loaded alpine and cross-loaded features.
Despite all the increased precipitation, persistent slabs may linger within the upper 200 cm of snowpack. Triggering may still be possible in areas without a thick and supportive surface crust.
Continued evidence of a widespread wet cycle, with numerous natural avalanches (up to size 3-3.5), was reported throughout the region. These included cornice falls, wet slabs and loose wet avalanches from all aspects and elevations.
Several persistent slabs were also running naturally with impressive propagation. Some features have run full path, reaching the valley bottom.
If you are heading into the backcountry, please consider sharing conditions via the MIN.
Up to 5 cm of new snow has fallen at upper elevations. This overlies a developing melt-freeze crust and/or wet surface snow.
Below this, 30 to 50 cm of wet snow sits above a crust (1 to 10 cm thick), buried in early March.
The widespread avalanche cycle has likely flushed the persistent slabs in the top 120 cm of the snowpack, but may still linger in areas where avalanche paths have not yet released.
The mid/lower snowpack is well settled and strong in most areas.
The snowpack rapidly diminishes at lower elevations and is moist to the ground in shallower areas.
As freezing levels drop, a widespread crust will form on all aspects at all elevations.
