Use caution in steep terrain at high elevations where storm slabs could be triggered. Early-season conditions prevail.
Around 10 to 20 cm of snow may rest on a wet snowpack. This new snow may take a day or two to bond. Use caution in steep, committing terrain features at higher elevations.
We expect that many avalanches occurred in the region over the past few days from wet, stormy conditions. Looking forward, riders could trigger storm slab avalanches in steep terrain features at high elevations.
Around 10 to 20 cm of snow likely accumulated at higher elevations, particularly in the southern extent of the region. This snow sits on wet snow that will slowly freeze into a hard melt-freeze crust.
A spotty surface hoar layer may be found about 20 to 30 cm deep. It is likely that the intense rain from earlier this week either avalanched or squashed this layer, but it could linger in isolated features.
The middle and base of the snowpack may also be moist from the rain, though weak faceted grains could persist where the snowpack isn't fully moist.
Snowpack depths at treeline are approximately 30 to 60 cm. The snowpack tapers drastically with elevation below treeline.
