Confidence

Moderate

Avalanche Summary

No recent avalanches have been reported.

Strong northeast wind could form isolated wind slabs on Sunday, but wind slabs will be larger and more likely on Monday.

Snowpack Summary

New snow is gradually accumulating, with heavier snow on Monday expected to bring the storm totals into the 20 to 40 cm range. Surface conditions will be shaped by northeast winds that are forecast to increase throughout the day on Sunday.

Snow depths in Long Range Mountains average about 80 cm in wind-sheltered areas and are much more variable in wind-exposed areas. The snowpack structure is strong and bonded.

Cornices have been forming along northeast-facing ridges.

  • Fresh wind slabs will likely form throughout the day, diligently watch for changing conditions.
  • Avalanche danger is often elevated in alpine gullies where snow has accumulated.

Avalanche Problems

Northeast wind could form wind slabs form on the steep sides of gullies (see cross-loading in the glossary). These slabs will be small and isolated on Sunday, but potentially larger by Monday.

Aspects: South West, West, North West.

Likelihood: Possible

Expected Size: 1 - 2
