Watch for fresh storm and wind slabs at higher elevations, where a thick surface crust does not exist.

Summary

Confidence

Low

Avalanche Summary

We expect that natural avalanche activity has stopped since the temperatures have dropped in the aftermath of Monday's storm. No new avalanches have been reported.

If you're heading out in the backcountry, please consider sharing any observations on the Mountain Information Network

Snowpack Summary

In alpine areas approximately 20 to 50 cm of recent snow sits over various layers of crusts, faceted snow, and potentially surface hoar in sheltered areas.

At lower elevations, below roughly 1800 m, a widespread thick crust exists. This crust should provide a bridge over any previous layers of concern deeper in the snowpack.

Thursday Night

Partly cloudy with no precipitation, northwest alpine winds 10 km/h, treeline temperature -8 °C.

Saturday

Mostly cloudy with 0 to 2 cm of snow, south alpine winds 30 to 50 km/h, treeline temperature -5 °C.

Sunday

Cloudy with 0 to 2 cm of snow, southwest alpine winds 10 to 20 km/h, treeline temperature -4 °C.

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Don't be too cavalier with decision making, storm slabs may remain sensitive to human triggering.
  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
