    The avalanche cycle in the alpine has eased from earlier in the week but we will see it ramp up with more snow on Saturday night. This loading pattern is looking perfect for increasing the size  and instability of existing cornices.

    A field team in the Icefields area on Wednesday remotely triggered several slab avalanches and experienced extensive whumphing at tree line elevations. Care is needed as you navigate slopes in this elevation band.

Weather Forecast

Our forecast models are calling for heavy snowfall in the Icefields area starting on Saturday evening . This combined with moderate to strong south westerly winds and relatively warm conditions should lead to an increase in the avalanche hazard.

Snowpack Summary

Very strong winds and mild temperatures earlier in the week have led to touchy slab conditions, particularly at tree line. Good skiing can still be found in sheltered locations but care should be taken in selecting your line.

Avalanche Summary

Field team remotely triggered several avalanches in the Parker Ridge and Hilda Creek area on Wednesday. These stiff slabs were easily triggered from adjacent slopes and combined with extensive whumphing highlights the unstable nature of the snow at treeline in certain locations.
