Danger ratingsProblemsDetails

Pay attention once the wind starts to blow, east winds and 15-30 cm of recent storm snow may form fresh, reactive wind slabs on lee features at upper elevations during the day on Monday.

Terrain and Travel Advice:
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Be carefull around freshly wind loaded features.
  • Avoid exposure to slopes that have cornices overhead.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
Wind Slab

As east winds increase through the day Monday, watch for fresh wind slabs forming on north and west slopes at upper elevations.

Avalanche Summary

On Saturday, several natural loose dry avalanches, up to size 1, were reported at treeline and above. A skier accidental size 1.5 storm slab avalanche was reported on a steep, north aspect at 1500 m.

Snowpack Summary

15-30 cm of recent snow and light to moderate southerly winds have formed small wind slabs on lee features at upper elevations.

These slabs overlie hard crusts on all sunny aspects and mixture of decomposing dry snow and possible small surface hoar in isolated locations on shady aspects.

The mid and lower snowpack is generally well settled and strong.

At the bottom of the snowpack, a layer of weak facets remains present and continues to be monitored for signs of reactivity.

Weather Summary

Sunday Night

Scattered clouds clear through the night. Light southeast ridgetop wind. Temperatures at treeline reach a low of -8 C. Freezing levels drop to valley bottom.

Monday

Mainly sunny with a few convective clouds bringing isolated localized flurries, trace accumulation. Moderate east ridgetop wind. Temperatures at treeline reach a high of -3 C. Freezing level 1500 m.

Tuesday

Sunny. Strong east ridgetop wind. Temperatures at treeline reach a high of -2 C. Freezing level 1600 m.

Wednesday

Sunny. Light northwest ridgetop wind. Temperatures at treeline reach a high of 0 C. Freezing level 1800 m.

More details can be found in the Mountain Weather Forecast.

Confidence: high
The snowpack structure is generally well understood.

Wind Slab

As southeast winds increase through the day Monday, watch for small pockets of fresh wind slab forming on north and west slopes at upper elevations.

Avalanche Summary

On Saturday, several rider triggered dry loose avalanches up to size 1 on steep treeline and alpine features. A few small natural and skier triggered wind slab avalanches were reported at treeline where the wind had built more cohesive pockets of snow.

If you head out in the backcountry, let us know what you are seeing by submitting a report to the Mountain Information Network.

Snowpack Summary

15-30 cm of recent snow and light southwesterly wind may have formed small wind slabs on lee features at upper elevations.

Below the recent snow is a melt-freeze crust, existing on all aspects at treeline and below. The crust extends to mountain tops on sunny aspects. In north facing high alpine terrain the surface snow may have remained cold and dry.

The mid and lower snowpack are generally well settled and strong.

Weather Summary

Sunday Night

Mostly cloudy with isolated flurries, trace accumulation. Light southeast ridgetop wind. Temperatures at treeline reach a low of -5 C. Freezing level 800 m.

Monday

Mainly sunny. Moderate southeast ridgetop wind. Temperatures at treeline reach a high of +2 C. Freezing level 1500 m

Tuesday

Sunny. Strong east ridgetop wind. Temperatures at treeline reach a high of +3 C. Freezing level 1700 m.

Wednesday

Sunny. Light northeast ridgetop wind. Temperatures at treeline reach a high of +4 C. Freezing level 1700 m.

In areas where deep persistent slabs may exist, avoid shallow or variable depth snowpacks and unsupported terrain features.
Small isolated wind slabs may be found on exposed lee features in the alpine and below ridgetops. Carefully evaluate steep lines for wind slabs before committing to them.

Terrain and Travel Advice:
  • In areas where deep persistent slabs may exist, avoid shallow or variable depth snowpacks and unsupported terrain features.
  • Avoid exposure to slopes that have cornices overhead.
  • Carefully evaluate steep lines for wind slabs.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
Deep PersistentSlab

A layer of weak facets sits near the base of the snowpack. This layer is most likely to be problematic in steep, wind affected terrain where the snowpack depth varies from thick to thin. Especially in the northern part of the region around the Chilcotins, Birkenhead, and Hurley.

Recent natural avalanche activity was observed on this layer, likely triggered by warm temperatures and strong sunshine heating the snowpack.

Wind Slab

10-20 cm of recent snow and light to moderate southwesterly wind may have formed small wind slabs on lee features at upper elevations.

Avalanche Summary

No new avalanches were reported in the region on Saturday.

On Friday, a couple of cornice failures triggered loose dry avalanches up to size 2 on large alpine slopes.

A couple of deep persistent slab avalanches were reported this week. On Wednesday, a cornice fall entrained a mass of snow which then triggered a size 3 deep persistent slab avalanche. It occurred at 2350 m on a north east facing slope. On Tuesday, a size 2.5 deep persistent slab avalanche was reported in the South Chilcotin range, around 2200 m on a south-facing slope.

Snowpack Summary

10-20 cm of recent snow and light to moderate southwesterly wind may have formed small wind slabs on lee features at upper elevations.

Below the new snow is a melt freeze crust exists on all aspects at treeline and below, and on solar aspects to mountain top. On high north aspects is a mixture of decomposing dry snow and small surface hoar in isolated locations.

The mid-snowpack is generally strong but the lower snowpack is a different story.

A weak layer of sugary facets is still prominent at the base of the snowpack. Small surface avalanches and cornice falls are the most likely things to trigger this layer. However, there remains a significant concern for human triggering in rocky, shallow, or thin-to-thick snowpack areas at treeline and above.

Weather Summary

Sunday Night

Clear skies. Light southeast ridgetop wind. Temperatures at treeline reach a low of -8 C. Freezing levels drop to valley bottom.
