Continue to use caution around wind loaded features. Previous strong winds will mean that wind slabs could be found lower down slope and propagate further then expected.

Travel and Terrain Advice

  • Keep your guard up at lower elevations. Wind slab formation has been extensive.
  • Avoid slopes that sound hollow or drum-like.
  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
  • Be especially cautious as you transition into wind affected terrain.

In the White Pass area, up to 40 cm of new snow has been redistributed by strong southerly winds into wind slabs in lee areas at all elevations. The strong winds could mean that wind slab is found further down slope then you might expect.

Details

Avalanche Summary

When the sun came out on Friday, several natural loose wet avalanches up to size 1.5 were observed in thin snowpack areas inland from White Pass. These avalanches entrained most of the snowpack, pulling pockets of slab in the track.

Snowpack Summary

A significant storm brought around 40 cm of new snow to the White Pass area late last week. The accompanying strong to extreme southerly winds left a heavily wind-affected surface at all elevations comprised of deep deposits of hard wind slabs, sastrugi, and areas stripped back to the ground or old crusts.

Below the new snow, a variety of old surfaces exists including a thin rime crust at treeline and hard old wind slabs at higher elevations. In the past week, warm temperatures have promoted settlement and bonding in a hard, consolidated mid-snowpack. The lower snowpack is weak and facetted above the ground surface.

Weather Summary

Sunday night: some light flurries with light to moderate southwest winds. Low of -5 at White Pass.

Monday: Cloudy, light snowfall. Winds increasing to strong from the southwest. High of -3 at 1100m.

Tuesday: light snow throughout the day with moderate to strong southwest winds. High of -3 at 1100m.

Wednesday: light snow throughout the day with light to moderate southwest winds. High of -5 at 1100m.

Danger Ratings Explained

1 - Low

Generally safe avalanche conditions. Watch for unstable snow on isolated terrain features.

Natural and human-triggered avalanches unlikely.

Small avalanches in isolated areas or extreme terrain.

2 - Moderate

Heightened avalanche conditions on specific terrain features. Evaluate snow and terrain carefully; identify features of concern.

Natural avalanches unlikely; human-triggered avalanches possible.

Small avalanches in specific areas; or large avalanches in isolated areas.

3 - Considerable

Dangerous avalanche conditions. Careful snowpack evaluation, cautious route-finding and conservative decision-making essential.

Natural avalanches possible; human-triggered avalanches likely.

Small avalanches in many areas; or large avalanches in specific areas; or very large avalanches in isolated areas.

4 - High

Very dangerous avalanche conditions. Travel in avalanche terrain not recommended.

Natural avalanches likely; human-triggered avalanches very likely.

Large avalanches in many areas; or very large avalanches in specific areas.

5 - Extreme

Avoid all avalanche terrain.

Natural and human-triggered avalanches certain.

Large to very large avalanches in many areas.
