Start early and finish early. Avalanche hazard will decrease rapidly with solar radiation.

Avalanche problems

  • Cornices

    30-40cm slab sitting on top of the April 13 melt/freeze crust. These storm slabs could also be triggered by solar radiation.

  • Loose Wet

Avalanche Summary

No observations today.

Snowpack Summary

Within the top 10cm of the snowpack, a temperature crust exists to approximately 2200m. The main concern is a 30-40cm slab that is sitting on the April 13 melt/freeze crust. The interface is slowly gaining strength but is still a concern for triggering avalanches. Stronger solar radiation is expected for Wednesday which in turn can produce wet avalanches on solar aspects and possibly trigger the most recent storm slab. Start early and finish early.
