Points saillants

As the recent storm snow settles, the risk of both natural and human-triggered avalanches on steep, sun-exposed slopes will increase throughout the day.

Avalanche Summary

On Tuesday, a variety of avalanches were reported following the recent storm. These include natural loose wet avalanches at lower elevations and natural or skier-triggered storm and wind slab avalanches at higher elevations. All the reported avalanches were relatively small, none exceeding size 2.

Snowpack Summary

Approximately 40 cm of recent snow has buried a widespread crust in all but sheltered, north-facing slopes where isolated pockets of surface hoar and/or faceted grains may exist below the new snow.

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

Terrain and Travel Advice

  • Give the new snow time to settle and stabilize before pushing into bigger terrain.
  • Be especially cautious as you transition into wind affected terrain.
  • Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet
