Start on small features and retreat to mellower terrain if you find signs of instability.

Watch for changing conditions, storm slabs will get deeper and more reactive through the day.




Avalanche Summary

On Sunday, northeast of Stewart, a large (size 2) helicopter triggered avalanche was reported on a wind-loaded northwest facing slope around tree line.

If you are getting out in the backcountry, consider making a post on the MIN (Mountain Information Network).

Snowpack Summary

By the end of the day on Monday, expect 30-60 cm of soft snow on the surface in sheltered terrain. This covers 30 cm of settling snow that sits on a widespread crust in all but sheltered, north-facing slopes where isolated pockets of surface hoar and/or faceted grains may exist below the recent snow.

Moderate to strong south or southwest winds will likely be forming deeper, more reactive deposits of snow in leeward terrain.

Previously problematic layers deeper in the snowpack appear to have bonded and strengthened, however, there is a small chance that they could remain a risk in steep, north-facing, high alpine terrain.

Terrain and Travel Advice

  • Make observations and assess conditions continually as you travel.
  • Watch for changing conditions today, storm slabs may become increasingly reactive.
  • Avoid areas where the snow feels stiff and/or slabby.
  • Be careful to keep storm day fever from luring you out into bigger terrain features.
