    This avalanche problem remains a concern and may become more sensitive to triggering as temperatures rise and penetrate into the snowpack.

    Steep alpine faces are sluffing regularly as new snow accumulates.

Weather Forecast

New snow and rising temperatures are in the forecast.  A light southerly flow will bring 10 cm of new snow to the Columbia Icefield area and we may see greater amounts in specific locations. Temperatures are expected to remain below freezing at treeline and above but valley bottoms may see numbers as high as + 8 degrees.

Snowpack Summary

Mid pack remains supportive. About 20 cms of HST overlies old surface. No slab in storm snow. At low elevations a buried sun crust is present on south through sw aspects.

Avalanche Summary

No new avalanches

Confidence

Intensity of incoming weather systems is uncertain
