In sintesi

Remember to pay attention to how the snowpack is reacting to the rising daytime temperatures, and the best risk management strategy is usually to start and finish your trip early.

Problemi valanghivi

  • Cornices

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco

    Avoid direct exposure to cornices as the temperatures rise. Cornice failures are a bad situation anytime.

  • Loose Wet

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco

    This problem is unreactive in the morning and increases sensitivity with afternoon warmth and sun. It is critical to evaluate the degree of overnight freeze and relate it to how quickly this problem can activate during the day.

Avalanche Summary

No new avalanches were observed or reported.

Snowpack Summary

Up to 10cm of snow with variable wind effect overlies a strong midpack above 2400m on shaded aspects. Sunny aspects, and everywhere below 2400m, starts in the morning as a supportive surface crust that breaks down with solar input and rising daytime temperatures.

Weather Summary

Mountain Weather Forecast is available at Avalanche Canada

Saturday night will be clear, light flurries, and -5 °C. Sunday might bring clouds, flurries, maybe 4cm of snow, gusting strong winds, 1600m freezing level, and -4 °C. Monday will be a mix of sun and cloud.

Terrain and Travel Advice

  • Avoid steep slopes when air temperatures are warm, or solar radiation is strong.
  • Minimize your exposure time below cornices.
