Kernpunkte

One size 3 avalanche was noted today off an alpine ridgetop likely cornice triggered. Another 15cm is expected Friday night with a possible E flow Saturday evening delivering additional accumulations at Maligne and Icefields.

    Thursday night Maligne received 30cm and Icefields 5-20cm. Another 10-15cm may arrive Friday into Saturday. Winds continue to build slabs and add load potentially to a slippery crust from earlier sun effect particularly on steep solar aspects.

    The buried surface hoar layer 70-120cm down remains a concern in areas that have not avalanched. The layer is still being observed at treeline and below treeline locations yet 'generally' layers are bridging it above. Cautious of shallow locations.

    Recent cloud cover has reduced daytime heating. Still be cautious if the sun pokes out as avalanche activity will increase quickly particularly on steep S or W aspect rock bluffs or gullies.
