Highlights

Remember that the avalanche hazard will increase rapidly with daytime heating. Timing and aspect will play a big part in your trip planning.

    Wind slabs exist in the upper snowpack that feel drummy in some areas. Take the time to dig down and evaluate the interfaces in each specific terrain feature.

    Intense solar radiation at this time of year can quickly elevate avalanche activity on solar aspects. Solar radiation is still a concern on cloudy days, especially without an overnight freeze. Time your exposure to these slopes to avoid the heat of the day.

Weather Forecast

Tuesday morning will start out with a temperature of -7c with cloudy skies. By noon, expect the sun to come out with the temperature rising to -1c in the alpine. Winds are forecast at 15-30km/hr from the SW with a freezing level of 2200m. 

Avalanche Summary

No new avalanches have been observed.

Snowpack Summary

With the heat from this last weekend, all solar aspects have melted during the day and frozen at night. With these kind of Spring conditions, timing and aspect is everything. The alpine appears to be wind affected except for sheltered north aspects. On non-solar aspects there are still some buried wind slabs in the upper 60 of the snowpack that are worth investigating before committing to bigger terrain. Be alert on the changing snow conditions under your skis. There are plenty of big cornices out there so take the time to plan your trip to avoid them.

Terrain and Travel

  • Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet
  • Avoid rock outcroppings, convexities, and anywhere the snowpack is thin and/or variable.
  • Be alert to conditions that change with elevation and sun exposure.
  • Cornices become weak with daytime heating.
