Wind slabs are becoming more reactive in recent days. Generally poor ski quality, but fast travel and long days for those extended tours. Plan your trip to avoid sun-exposed slopes in the afternoon as we transition to Spring.

Weather Forecast
A mix of sun and cloud is expected on Tuesday with mild temperatures. Freezing levels should reach near 2000m. Winds will be out of the west at 30km/h at ridge top.
Avalanche Summary
On Saturday a skier triggered a size 2.0 full depth slide on a steep and shallow south aspect at 2700m. No injuries or burial, but the skier was carried approximately 400m down slope. The last 48 hours have seen an increase in wind slab activity as well. These have all been small, thin wind slabs triggered either naturally or by skiers in the alpine and open areas at treeline. Typically the trigger zones are steep and unsupported features.
Snowpack Summary
Widespread wind affect in alpine and open areas at treeline. Prominent in these areas are hard wind slabs, soft wind slabs, and breakable wind crusts. Reverse wind loading is also evident due to a recent wind event from the north. Sun crusts are dominant on solar aspects. The ski quality is reasonable on polar aspects below 2300m if you can find an area without tracks. The November facet/depth hoar layer is a live and well and has been responsible for a recent skier-triggered avalanche. See avalanche activity.
