Pay attention to the wind. If it picks up, fresh reactive wind slabs are likely to form.

Use caution in wind-affected terrain, human-triggered wind slab avalanches remain possible.

Moderate

Avalanche Summary

No new avalanches were reported in this region over the past few days. However, field observations are currently very limited.

If you go into the backcountry, please consider submitting your observations to the Mountain Information Network. 🙏

Snowpack Summary

Up to 10 cm of new snow will accumulate by the end of the day on Thursday. This overlies up to 30 cm of recent snowfall.

Below the recent snow is a crust everywhere except true north facing terrain at upper elevations.

The facet/crust layer that produced large avalanches during early March is down 80 to 150 cm. It is currently considered to be dormant in most locations.

Many areas below treeline are either snow free or have very thin snow coverage. Expect difficult travel at lower elevations.
