Avalanche Forecast

Many natural and rider-triggered avalanches released on Thursday on the weak layers described in the Snowpack Summary (see photos below). These weak layers may take some time to strengthen, meaning they will likely remain active to human traffic for the foreseeable future.

Please consider sharing your observations to the Mountain Information Network.

The alpine has received around 50 cm of snow over the past week. Wind from variable directions may have hardened the snow surface in wind-exposed terrain and formed deeper deposits in steep terrain near ridges.

The snow surface on south and west aspects may become moist in the afternoon.

Weak layers of surface hoar crystals and/or faceted grains may be found around 30 to 70 cm deep under the storm snow. This layer has produced recent avalanche activity and is unstable in snowpack tests.

Cornices are large and looming at this time of year.

Saturday Night

A mix of clear skies and cloud with around 5 cm of new snow. 15 to 30 km/h south alpine wind. Treeline temperature -6°C.

Sunday

Mostly cloudy with 2 cm of new snow in AM, clearing in PM. 20 to 35 km/h north alpine wind in afternoon. Treeline temperature -3°C.

Monday

Sunny. 20 to 35 km/h north alpine wind. Treeline temperature -3°C.

Tuesday

Sunny. 5 to 15 km/h southwest alpine wind. Treeline temperature -2°C.

More details can be found in the Mountain Weather Forecast.

• Be aware of the potential for larger than expected storm slabs due to the presence of buried surface hoar.
• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
