Points saillants

Mainly cloudy skies and cooler temperatures should keep the hazard level down, but anytime the sun is shining watch for a rapid increase in hazard on solar aspects.

    Isolated pockets of wind slab are found in wind prone terrain in the Alpine.

    Problem exists in steep Below Treeline features as the crust breaks down with day time warming. Solar aspects at all elevations are also subject to this avalanche problem whenever the sun shines.

Weather Forecast

Up to 10cm of new snow is possible through Wednesday night with a nice cool start on Thursday morning (temps near -10C). This will warm to around -6C with light to moderate westerly winds.

Thursday and Friday also look to be relatively cool with a mix of sun and cloud.

Avalanche Summary

Some pin wheeling and small loose wet avalanches on steep solar aspects at lower elevations.

Snowpack Summary

Continued melt freeze cycle happening on all Solar aspects at all elevations and all aspects below tree line. Depending on the extent of the warming and solar radiation, we are seeing the top 5-20cm break down and sluffing off in wet loose avalanches . On North aspects, expect to find a crust up to 2300m, with dry snow above that elevation. The snowpack has not yet transitioned to a full "Spring" snowpack, but it is getting there.

Terrain and Travel

  • Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet
  • Be alert to conditions that change with elevation and wind exposure.
  • Cornices become weak with daytime heating or solar exposure.
  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
