Description:
There is a LOW danger for windslab avalanches around the skiarea and the lower elevations of the National Park. However around the high peaks at the divide the danger is a MODERATE danger as there has been more snow for transport available. Some pockets of shallow wind slab have formed on lee aspects above 1800m. Some of them are sitting and a firm crust which can act as a sliding layer. Freshly loaded looking zones and crossloaded features should be avoided as the load of a single skier or climber could trigger a wind slab. These might be small but be aware of what`s below you as even a small slab could take you over a rocky feature.

Current Snowpack Conditions

Current Snowpack Conditions
In general a shallow snowpack - under the annual average exists in the forecast area.
There are up to 30 cm cold fresh snow sitting on a raincrust. Strong to gale force southerly winds have picked up and transported the cold dry snow around to start zones in the northern half and fresh slab formations have been observed. Some patches have been stripped down to a firm slippery surface - mainly on the western aspects.
At lower elevations the transport has been minimal. Below 1700m most areas are below threshold. Some slippery and icy patches can be expected on the slopes.

Mountain Weather

Mountain Weather
Some morning cloud.
South west winds up to gale force at times in the mountains. The southerly airflow keeps on delivering cold temperatures.

Sliding Danger

Slide For Life
The conditions on the snow are variable, expect to come across firm and icy snow patches and be prepared to stop. Some slopes can be very slippery in places.
Expect icy conditions on some alpine walking tracks. Travel with caution and carry an ice axe and crampons.
