Avalanche Summary

No new avalanches have been observed or reported in the bulletin region in the last few days.

Snowpack Summary

The snowpack is highly variable across the region. The Icefields area has 60-90 cm at tree line and the Maligne area has 10-15 cm. Since the Nov 13 storm, moderate SW winds have transported snow in open areas, and Nov 18 brought up to 5 mm, falling as rain at tree line and below. There is not yet much information available about the early season snowpack structure, so be sure to dig down and investigate if you're heading out, and post your observations to the MIN!

Weather Summary

Wednesday: Sunny with cloudy periods. Precipitation: Nil. Alpine temperature: High -5 °C. Light ridge wind. Freezing level at valley bottom.

Terrain and Travel Advice

  • Small avalanches may cause climbers to fall or bury belayers and gear.
  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for slabs before you commit to it.
