Highlights
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.
Avalanche problems
Loose Wet
Unlikely · Size 1
The snowpack may soften on steep solar aspects. The snowpack is well consolidated, so loose wet avalanches are unlikely.
Wind Slabs
Unlikely · Size 1
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.
