In sintesi

Significant rain is expected at all elevations. Temperatures will remain above zero until Saturday morning, making wet loose avalanches the primary concern.

Exercise caution on steep slopes with moist surface snow, as wet avalanches may run bigger and farther due to a solid crust underneath.

    West wind continues to blow, potentially building wind slabs at upper elevations.

    The park has received significant amounts of rain, and more is expected in the coming days which will increase the likelihood of wet loose avalanches.

Confidence

Moderate

  • We are uncertain about how the timing or intensity of warming will affect the snowpack.

Avalanche Summary

One size 2.5 wind slab avalanche and several wet loose avalanches to size 2 were observed on Wednesday along the Akamina Parkway.

Snowpack Summary

New precipitation is falling as snow/rain in the alpine and as rain at treeline and below treeline. Snow is moist at all elevations. A crust is down 20-40cm and 2-8 cm thick with several other crusts deeper in the snowpack. The mid and lower snowpack is generally well settled with total snowpack depth ranging from 130-220 cm at treeline and in the alpine. 40-120cm below treeline.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Recent strong wind means wind slabs may be found farther downslope than expected.
