A skier released a size 1 hangfire slab (overburden from a previous avalanche) in the northern part of the region on Sunday. The avalanche occurred on a south aspect at 900m and is thought to have reacted on the early February interface. Most other relevant avalanche activity reported was from a natural storm cycle that occurred a few days ago.

Continued strong and variable winds have redistributed light amounts of recent storm snow into thin wind slabs that most commonly exist at treeline and in the alpine. In the northern part of the region two persistent weak layers are on the radar of some operators: Surface hoar buried at the beginning of March is as much as 70cm deep. The early February persistent weak layers (surface hoar, facets, crusts) are over a metre down. Although not widespread throughout the region, persistent slabs would be destructive in nature and may be reactive to skier triggers, particularly below treeline on isolated and sheltered steep terrain where buried surface hoar may be preserved. Cornices in the region are reported to be very large and unstable.
