Recent report of natural icefall occurred on the Loft Glacier, triggering a size 2.5 slab avalanche. Natural avalanches to size 2.0 and rider triggered to 1.5 have also been reported. Isolated areas with no wind effect, and steeper terrain features the new storm snow is sluffing.

Up to 30 cm of new snow fell over the weekend. This adds to the previous storm snow, with 45-60 cm being an average amount over the mid February layers. Recent, intermittent clear skies have created a sun crust on south facing terrain into the alpine.The mid February layers are a strong melt freeze crust at lower elevations (below 1000m) and wind effected snow higher in the alpine while between these elevations, the interface varies wildly from facets, surface hoar, sun crust or wind press. The surface hoar is not widespread but is responsible for much of the recent avalanche activity. With the additional wind loading, pockets as deep as 70cm are possible on lee features. To compound the wind slab issue, recent winds have been northerly, building reactive slabs on south facing terrain features. The mid and lower snowpack is generally well settled and strong.
