Lo esencial

Sunny blue skies are uplifting for our mental health, but they can be destabilizing on steep, solar-facing slopes. Enjoy the sun's rays, but limit your overhead exposure if you're basking in its warmth.

    Strong SW winds accompanied Sunday night's storm, creating wind slabs in Alpine and Treeline lee features. Caution is mandatory when transitioning into wind-affected areas, especially if direct sun is hitting the slope.

Confidence

Moderate

Avalanche Summary

Strong solar input Tuesday resulted in numerous avalanches to sz 2.5 from southerly aspects within the highway corridor. Small, moist point releases could be observed in many lower elevation S aspects as well.

Both Cheops 2 and Grizzly Couloir spit out sz 2 slab avalanches Monday evening.

Snowpack Summary

Strong SW winds and snow from Sunday's storm formed a wind slab in lee and crossloaded features at Alpine/Treeline elevations. Sheltered areas hold deep, unconsolidated powder.

Solar aspects are moist in the direct sun, then refreezing with a breakable crust once the sun is off them.

Weather Summary

A ridge of high pressure will keep snow at bay until clouds return later Thurs.

Tonight: mainly clear, Alp low -15*C, light W winds

Wed: sun and cloud, Alp high -10*C, light SW winds

Thurs: flurries in PM, 10cm, Alp high -10*C, moderate SW winds

Terrain and Travel Advice

  • Minimize exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Use small low consequence slopes to test the bond of the new snow.
