    Slabs are thin and in areas where snow is available for transport. Forming on lee slopes, below ridge lines and cross loaded gullies.

Weather Forecast

Cooler temperature and up to 15cm of snow is forecast for the next 48 hours. Winds will be light to moderate from the South and Southwest.

Snowpack Summary

The cooling trend has helped form a crust layer up to 2,500m. SW winds continue to build thin windslabs at treeline and into the alpine. A sliding layer may exist below this where the slab covers the crust formed from recent rain and warm temperatures. The snow is absent in the valley bottom. Early season conditions prevail.

Avalanche Summary

Cooler temperatures with overnight freezing has brought an end to the moist snow avalanche cycle.
