Kernpunkte

Heads up-we have entered Spring Conditions. Conditions can change dramatically throughout the day.Start EARLY and finish EARLY!

Lawinenprobleme

  • Cornices

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–3
    Cornices are large and can collapse anytime. Stay well back from the edge while traveling along ridge lines. Pay attention to what is above and avoid cornice exposed slopes.

  • Loose Wet

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible - Likely
    Größe
    1–3
    As temperatures warm up so does the potential for loose wet avalanches. It may be enough to trigger deeper basal layers on steeper unsupported slopes.

Weather Forecast

Clouds rolling in this evening bringing wet conditions and cooler temps over the next few days. Expect typical moist April conditions.

Snowpack Summary

Warm temps and high fzl have added load to upper snowpack.  At treeline, lee aspects have a series of windslabs sandwiched with thin weaknesses in the upper snowpack. A strong midpack bridges over weak basal facets on Northerly aspects at treeline and above.

Avalanche Summary

Numerous loose wet avalanches to size 2.5 noted today at most elevations- some running on crusts and others scouring to ground. Cornice failures to size 2.5 have occurred around the Icefields area on North to East aspects. They did not initiate a slab on the slopes below.
