Regions: Glacier.

Rain and warm temperatures haven't allowed the surface crust to recover. It may break down rapidly today

Weather Forecast

Friday: Cloudy with scattered wet flurries accumulating to 4cm, high -2, moderate SW wind gusting to 65, freezing level 2500m

Friday night: Cloudy with isolated flurries

Saturday: Cloudy with scattered flurries accumulating to 4cm, high -4, light W wind, freezing level 1700m

Sunday: Sun and cloud, nil precipitation, light W wind, freezing level 2000m

Snowpack Summary

A spring snowpack is rain soaked and contains several crusts. Very high N alpine may hold dry snow if you can get there. Check out this link for more info on spring conditions. Expect the forecasted rain and warm temperatures to continue to destabilize the snowpack.

Avalanche Summary

A natural sz 2.5 was observed this morning from Cougar Creek West and a few infrasound detections suggest natural activity with the rain. Cornice falls and glide slabs have been releasing more frequently recently.

Confidence

Avalanche Problems

Loose Wet

A poor overnight crust recovery, rain soaked upper snowpack and new wet snow will make wet slides easy to trigger. Its also possible for wet slides to release naturally, be aware of the potential for slopes above to release

  • Use extra caution on slopes if the snow is moist or wet.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 1 - 3
