High Alpine: Above 2000m
Alpine: 1000 to 2000m
Low Alpine: Below 1000m
Description:
Continued snow showers will slowly keep building windslabs on slopes facing the Easterly half above 2000m. As of Monday afternoon the deepest deposits are around 30cm deep, and this seems to be located more in the Northern parts of the region. Human triggering will become a possibility as the snowfall and Westerly winds continue over the day. Be cautious on all recently windloaded slopes.

Recent Avalanche Activity

Recent Avalanche Activity
Explosive testing produced a very small size 1 slab avalanche on a North East facing slope at 2100m.

Current Snowpack Conditions

Current Snowpack Conditions
Between 15 - 30cm of new snow has been blown onto North East facing slopes above 2000m. This has bonded quite well to the old surface. There are weaknesses within it, but even large loads (explosives) have triggered only very small avalanches, and ski cutting has produced no results. This new snow came in mainly in Northern parts of the region, with only very small amounts reported from the Southern parts. Below 2000m the snowpack is very spring like.

Mountain Weather

Mountain Weather
Another mucky day for Tuesday. A few heavier falls in the morning falling as snow above around 1800m then scattered showers for the rest of the day with the snow level gradually lowering to 1300m. Moderate to strong Westerly winds.
