    Small loose dry avalanches should be expected in steep terrain, and may entrain significant amounts of snow in gully features.

Weather Forecast

Tuesday night will have a dusting of snow and calm winds. Wednesday will be variable clouds and seasonal temperatures. Some precipitation will occur Thursday into the evening with 5-10 cm and increasing SW winds.

Snowpack Summary

Pockets of wind slab can be found in exposed terrain tree line and above. These pockets are sitting on a weak layer of facets. Recent 10cm of new snow has helped to freshen things up a bit, but along with moderate Southwest winds has increased the likelihood of touchy new wind slabs on lee aspects.

Avalanche Summary

No patrol Tuesday. Monday there were reports of small size1 loose dry avalanches on steep solar terrain along the Icefields Parkway today. One size 1.5 windslab was observed at 2300m on a cross loaded feature.
