Lo esencial

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.

Problemas de aludes

  • Cornices

    • Alta montaña

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

    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.
