Regions

Northwest Inland, Kitimat, Nass, Rupert, Seven Sisters, Shames, Howson, Microwave-Sinclair.

New snow will form reactive storm slabs throughout the day on Monday.

If you notice signs of instability, such as shooting cracks in the new snow, retreat to non-avalanche terrain.

Confidence

Moderate

  • We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.

Avalanche Summary

On Friday and Saturday, numerous natural avalanches up to size 2.5 were observed throughout the region. Many of the observed avalanches are suspected to have occurred during the storm on Feb 10th and 11th.

Be sure to post your observations to the MIN if you get out!

Snowpack Summary

Approximately 30 to 60 cm of storm snow has accumulated, accompanied by strong southerly winds, burying a widespread crust that developed in early February. This crust is generally stronger and more supportive at treeline and above, while it is weaker or absent below treeline, where moist snow persists beneath the new snow.

A January 26 crust with surface hoar or faceted snow lies 60 to 120 cm deep, likely persisting only at higher elevations. At lower elevations, it has been rain-soaked and destroyed.

Otherwise, the snowpack is generally well settled and well bonded, with no other significant concerns.

Weather Summary

Sunday Night
Cloudy. 5 to 10 cm of snow. 10 km/h south ridgetop wind. Treeline temperature -5 °C.

Monday
Mostly cloudy. 4 to 10 cm of snow. 30 km/h east ridgetop wind. Treeline temperature -7 °C.

Tuesday
Mix of sun and clouds. 1 to 4 cm of snow. 40 km/h northeast ridgetop wind. Treeline temperature -13 °C.

Wednesday
Mostly sunny. 30 km/h east ridgetop wind. Treeline temperature -19 °C.

Terrain and Travel Advice

  • Watch for fresh storm slabs building throughout the day.
  • Avoid areas where the snow feels stiff and/or slabby.
  • Avoid freshly wind-loaded terrain features.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
