Freezing levels to reach 2500m during the day and may extend up to 2900m on Tuesday. Some models indicate that the Columbia Icefields Area could receive up to 30cm starting mid-week and continuing through the weekend.

Snowpack Summary

LIght scattered snowfall (drainage dependent) on supportive melt-freeze crust/mid-pack. Deep weak layers dormant when temperatures are below freezing but may be triggered as temperatures rise. Snowpack becoming non-supportive and isothermal during warmest part of the day on solar aspects and lower elevations.

Avalanche Summary

Numerous loose wet avalanches expected with daytime heating, particularly on steep solar aspects and steep terrain at lower elevations.
