Regions

Glacier.

Recent snowfall has overloaded the persistent weak layer causing a large avalanche cycle over the weekend. Natural avalanche activity has decreased but human triggering will remain likely.

See this MCR for a detailed avalanche summary.

Confidence

Moderate

  • We are uncertain about how quickly persistent slabs are gaining strength.

Avalanche Summary

Natural avalanche activity has slowed down but explosive testing was producing up to size 3.5 avalanches on Sunday.

On Friday, numerous natural and explosive triggered avalanches up to size 4 running into valley bottom.

See the following link to a recent Mountain Conditions Report.

Snowpack Summary

A crust has formed on the surface on solar aspects. Approx. 70 cm of recent snowfall has been redistributed by extreme southerly creating wind slabs on the surface.

The Feb 9 surface hoar (SH) is down 90-120 cm and remains reactive in snowpack testing. The Feb 9 SH sits over a crust on solar aspects.

The Jan 26th layer, composed of surface hoar/facets/crust, is buried down 130-160 cm. The largest surface hoar is preserved in sheltered areas below treeline.

Weather Summary

Sunshine until another frontal sysem arrives on Tuesday.

Tonight Cloudy with clear periods. Low -5°C. Wind SW 25 gusting to 50km/h. Freezing level (FZL) 600m.

Mon - A mix of sun and cloud. High -1°C. Winds SW 30 gusting to 55km/hr. FZL 1800m.

Tues Flurries, 9cm. High -3. Wind SW 25 gusting to 60.

Wed - Flurries, 7cm. High -3°C. Wind light gustingto 35 km/hr. FZL 1600m.

Terrain and Travel Advice

  • If triggered, wind slabs may step down to deeper layers, causing larger avalanches.
  • Be aware of the potential for large avalanches due to buried surface hoar.
  • Shooting cracks, whumpfs, and recent avalanches are strong indicators of an unstable snowpack.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
