    Natural and human triggering is unlikely but it is still a good practice to avoid steep, open, rocky slopes with a shallow snowpack.

Weather Forecast

Snow flurries are expected in the icefields area through Monday with very little accumulation. This will translate to light showers in the valley bottoms.  Cloudy skies with occasional sunny periods and scattered snow flurries will  carry on through the week with more snow accumulating in the icefields area.

Snowpack Summary

A supportive mid pack consisting of rounded and facetted layers is bridging the weak depth hoar/facet layers that make up the lower snowpack. Some wind slabs are developing in sheltered alpine locations on various aspects from recent NW to SW winds.

No new avalanches reported
