Avalanche Forecast

On Tuesday, our field team observed few natural wind slabs avalanches in north and east facing alpine gullies. These likely occurred during the weekend storm. Some wind slabs may still linger in alpine terrain and along ridgetops, and fresh slabs could form if the wind picks up this week.

25 to 45 cm of storm snow and moderate southerly winds have left wind slabs in open areas.

In the mid-pack, down around 50 to 80 cm, it could be possible to find a thin layer of facets between old wind slabs. This layer recently produced sudden results in snowpack tests.

The height of the snowpack is variable. In areas lee of the prevailing wind, depths up to 170 cm can be found. At the lower elevation treeline terrain, snow depths decrease and are roughly 60 to 90 cm.

Tuesday night

Cloud, no significant precipitation, 30 km/h wind from the southeast, treeline temperatures drop to -10 °C.

Wednesday

Cloudy with light flurries in the afternoon bringing up to 5 cm of snow, 20 to 30 km/h wind from the south, treeline temperatures around -8 °C.

Mostly cloudy, no significant precipitation, 20 km/h wind from the southeast, treeline temperatures around -12 °C.

Cloudy with light flurries bringing trace amounts of snow, 30 to 40 km/h wind from the south, treeline temperatures around -10 °C.

More details can be found in the Mountain Weather Forecast.

• Pay attention to the wind, once it starts to blow fresh sensitive wind slabs are likely to form.
• Seek out sheltered terrain where new snow hasn't been wind-affected.
• Carefully monitor the bond between the new snow and old surface.
