Points saillants

The snowpack will remain firm tomorrow with the forecast weather conditions. If travelling above the snowline, be prepared by making sure you have the right equipment for the conditions.

Problèmes avalancheux

    The snowpack may soften on steep solar aspects. The snowpack is well consolidated, so loose wet avalanches are unlikely.

  • Wind Slabs

    Above 2100 meters, a reasonable amount of snow has accumulated. Pockets of wind-loaded snow are possible on aspects lee to the previous northwest winds.

Recent Avalanche Activity

A previous loose, wet avalanche cycle has occurred throughout the region.

Current Snowpack Conditions

Rain as high as 2100 meters has washed away a lot of the early-season snow. Above 2100 meters, previous strong winds have resulted in a variable snowpack distribution, with the deepest snowpack on polar aspects lee to the north-west. Below 1700 meters, the snowpack is below threshold (not enough snow to avalanche).

Mountain Weather

Mostly cloudy with the odd shower.

Wind at 1000 metres

Southwesterly 30 km/h dying out in the afternoon.

Wind at 2000 metres

Westerly 55 km/h easing to 30 km/h in the morning.

Freezing level

1800 metres.

Sliding Danger

Snow remains on most of the main passes and tramping routes. Sliding into rock is a potential hazard. Ice axe and crampons should be part of your winter gear.

Forecast Confidence

High

  • The snowpack structure is well understood.
