Regions

Northwest Inland, Nass, Seven Sisters, Howson, Kispiox, Ningunsaw.

Monitor new snow amounts and reactivity as you investigate the outcome of the storm. Be ready to back off from avalanche terrain where you encounter signs of instability.

Confidence

Moderate

  • We are uncertain about forecast snowfall amounts.

Avalanche Summary

Skier traffic and ski cutting produced a few size 1 to 1.5 wind slabs in the region on Wednesday, consistent with an expected uptick in avalanche conditions with ongoing storms. The coastal region has been experiencing a larger, more widespread natural avalanche cycle. Expect conditions inland to increasingly follow this pattern as snowfall continues.

Observations remain limited by difficult weather, so be sure to post your observations to the MIN if you get out!

Snowpack Summary

15 - 25 cm of new snow should accumulate by end-of-day Friday, bringing new snow totals to a wind-redistributed 30 - 40 cm, roughly. The new snow has buried heavily wind-affected and crusty surfaces almost everywhere.

In shelter below 1000 - 1400 m there is large surface hoar on the old surface that will promote reactivity where slabs form over it. Warming and loose wet avalanche conditions may help neutralize the problem at these lower elevations.

The mid and lower snowpack is well settled with no current layers of concern. Treeline snow depths throughout the region range from 150 cm to 250 cm.

Weather Summary

Thursday Night
Cloudy with flurries bringing 10 to 15 cm of new snow, light rain below about 1300 m. 40 km/h southeast ridgetop wind. Treeline temperature 0 °C to 1 °C. Freezing level reaching 1500 m briefly.

Friday
Cloudy with continuing flurries bringing 5 - 10 cm of new snow, light rain below about 1200 m. 50 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1300 - 1400 m.

Saturday
Becoming a mix of sun and cloud after isolated flurries overnight with minimal accumulation. 40 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level rising from valley bottom to 1100 m.

Sunday
Mostly cloudy with scattered flurries bringing about 5 cm of new snow. 40 km/h south ridgetop wind. Treeline temperature 0 °C. Freezing level 1300 m.

Terrain and Travel Advice

  • Use increased caution at all elevations. Storm snow is forming touchy slabs.
  • Make observations and continually assess conditions as you travel.
  • Approach steep and open slopes at and below treeline cautiously, as buried surface hoar may exist.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.

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.

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
