In sintesi

"The River" will end, with clear cooler conditions in its wake. The warm temps and rain have however decimated the snowpack. Adequate snow coverage below treeline only remains in the SW corner of the park. There is still snow in the alpine and at treeline.

Avalanche Summary

Several new piles of wet loose debris to size 2.5 observed on a road patrol up Akamina Parkway. Uncertain of the failure plane.

Snowpack Summary

Rain has soaked and washed away the snowpack at all elevation. Free running waterfalls can be seen in alpine features up the Akamina Parkway. The snow that remains will begin to refreeze into crust as temperatures cool on Sunday.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Wet avalanche activity may step down to deeply buried persistent weak layers at lower elevations.
