Points saillants

Skiing is bad. Ice climbing looks good. Get after the routes you want while the danger is relatively low and the temperatures remain mild.

    Recent wind effect has destroyed most of the surface snow and left hard slabs which could be triggered from shallow snowpack areas. Watch for steep and unsupported areas of windloaded snow.

    The lower depths of the snowpack are slowly facetting and becoming weaker, especially in shallow areas. Choose the deeper snowpack areas for your travel.

Weather Forecast

A minor system embedded in a southwesterly flow will cross the Jasper region for Wednesday. Expect increasing winds, temperatures will fall slightly and no more than 5cm of new snow.

Snowpack Summary

Most slopes at treeline and alpine areas are seriously wind effected, with hard slabs in some areas, and scouring to rocks in others. These hard slabs overly a sporadically found weakness down 10-40 cm (Jan 4 surface hoar and facets). The lower snowpack is facetted and of variable strength, but overall stronger than expected for this time of year.

Avalanche Summary

No new avalanches were observed along the Icefields Parkway today.
