Continually assess conditions as you gain elevation. Larger and more reactive storm slabs will be found at higher elevations.
Avoid lee and cross loaded slopes.

Avalanche Summary
Wet loose avalanches up to size 2 have been observed on an ongoing basis for the past few days. We expect this type of avalanche activity to taper off as freezing levels fall.
We suspect that rider triggerable storm and wind slab will be found at treeline and above.
Snowpack Summary
Recent storm snow with southerly winds has likely formed wind slab on west through east aspects at upper elevations. As the freezing level falls a new crust will form on all aspects at treeline and below.
A crust from late March can be found down 50 to 80 cm on all solar aspects and at treeline and below on north facing terrain. Below this crust the snowpack is generally well settled.
