Points saillants

Forecast snowfall amounts are uncertain.

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

    Storm slabs may build through the day. Dial back your terrain choices as the snow deepens.

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.

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.
