Kernpunkte

The day generally starts at a low hazard and gradually increases as the day warms up. WATCH OUT if the sun pokes out increasing trigger-ability particularly on steep solar aspects.

Lawinenprobleme

  • Cornices

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    2–3

    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.

Snowpack Summary

Up to 10cm of snow with variable wind effect overlies a strong mid-pack 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.

Confidence

Moderate

Avalanche Summary

Monday's Icefield patrol had great visibility. No new avalanches were observed from 1100 to 1300hrs. Sunday's Maligne-Bald Hills patrol noted no new avalanches but visibility was limited to below mountain tops.

Terrain and Travel Advice

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