Weather Forecast

Light snow beginning Monday afternoon with 10 cm possible with light SW winds.  Clearing and cooling on Tuesday and then very warm conditions into the weekend.

Snowpack Summary

Huge variation in the snowpack across the forecast region!! The Icefields Area received around 1 meter of snow since Friday while areas to the north received much less. Sensitive storm slab can be found on all aspects at treeline and above. Rain and freezing rain fell below treeline in most areas.

Avalanche Summary

The natural avalanche cycle continues with slides up to 2.5 involving the new storm snow. Avalanche control efforts along the Icefields Parkway produced large avalanches around Polar Circus.

Confidence

Timing or intensity of solar radiation is uncertain on Tuesday
