In sintesi

Natural avalanche activity is expected to taper off with forecasted gradually cooling temperatures.

Be cautious in any steep terrain where the snow feels wet or punchy, or if it's facing into strong sun.

Avalanche Summary

Numerous natural avalanches were observed during the heat of the day on Tuesday in the icefields area. Loose Wet and Wet Slabs up to size 3 with most initiating in steep tree line and low alpine features. Some were failing in the mid-pack, and some were failing at ground depending on how isothermal the snowpack in that location.

Snowpack Summary

Melt-freeze crusts or wet snow exists on all aspects except North alpine, with many areas in some state of transition toward isothermal. The high alpine is still holding on to a winter snowpack on NW to NE aspects with the Jan 24th PWL down 80 to 120cm.
