Avalanche Summary

We haven't received any reports of avalanche observations in this region. Please consider sharing your observations using the Mountain Information Network (MIN).

Looking forward, riders could trigger lingering storm slab avalanches where the new snow hasn't bonded to the underlying snowpack. Use caution in steep terrain features at high elevations.

Snowpack Summary

Around 10 to 20 cm of snow sits on a hard melt-freeze crust. A spotty surface hoar layer may be found about 20 to 30 cm deep. It is likely that the intense rain from earlier this week destroyed this layer, but it could linger in isolated features.

The middle and base of the snowpack may also be moist from the rain, though weak faceted grains could persist where the snowpack is dry.

Snowpack depths at treeline are approximately 30 to 60 cm. The snowpack tapers drastically with elevation below treeline.

Weather Summary

Friday Night

Partly cloudy with no precipitation, 10 to 20 km/h southwest wind, treeline temperature -9 °C.

Saturday

Mostly cloudy with 1 to 3 cm of afternoon snow, south alpine wind 40 to 50 km/h, treeline temperature -8 °C.

Sunday

Cloudy with 1 to 3 cm of snow, south alpine wind 20 to 40 km/h, treeline temperature -5 °C.

Monday

Mix of sun and cloud with no precipitation, north alpine wind 20 km/h, treeline temperature -4 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the old surface.
  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.

Avalanche Problems

Storm Slabs

10 to 20 cm of snow rests on a hard melt-freeze crust. This snow is likely bonding but could linger as storm slabs in isolated terrain features. Use caution in steep, committing terrain, particularly where the snow surface is smooth.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
