Regions

Lizard-Flathead, Akamina, Flathead, Lizard.

Forecast snowfall amounts are uncertain.

The avalanche danger is likely to increase as the new snow piles up.

Confidence

Moderate

  • We are uncertain about forecast snowfall amounts.

Avalanche Summary

It's expected that avalanche activity will increase as the new snow piles up. Firstly, as dry loose avalanches, and then if we see more than 20 cm, storm slabs become possible.

Snowpack Summary

New snow is falling on a thin melt-freeze crust that made for tricky riding. It's expected that 15 to 30 cm will have fallen by the end of the day on Thursday.

A thick crust is buried 20 to 30 cm deep. Below it, up to 50 cm of rain-soaked snow sits on another crust (1 to 10 cm thick) from early March.

Persistent weak layers may linger within the top 150 cm of the snowpack. These are unlikely to trigger in most areas as a result of the thick crust bridging over them.

The mid and lower snowpack is strong in most areas. Snowpack depth tapers rapidly at lower elevations.

Weather Summary

Wednesday Night
Cloudy. 5 to 15 cm of snow. 10 km/h southeast ridgetop wind. Treeline temperature -2 °C. Freezing level 1600 m.

Thursday
Cloudy. 5 to 15 cm of snow. 10 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 1600 m.

Friday
Mostly cloudy. 1 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -3 °C.

Saturday
Mostly sunny. 40 km/h west ridgetop wind. Treeline temperature -2 °C.

Terrain and Travel Advice

  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • Watch for fresh storm slabs building throughout the day.
  • Loose avalanches may start small, but they can grow and push you into dangerous terrain.

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 Dry

Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
