Weather Forecast
Light flurries and a mix on sun and cloud are expected for the forecast period. Freezing levels are expected to sit between 1200m and 1400m. Winds should remain generally moderate from the southwest.
Avalanche Summary
On Thursday, explosives control triggered wind slab avalanches to size 1.5.No other recent avalanches were reported.
Snowpack Summary
New wind slabs have formed in high elevation lee terrain. These wind slabs overlie a variety of surfaces which include older wind slabs or melt-freeze crusts. Up to a metre below the surface you may find a hard crust which co-exists with facets, especially in the north of the region. Although reports suggest this layer has gained significant strength, I'd be wary of the possibility of isolated large avalanches on steep, unsupported slopes, especially if temperatures increase, or if solar radiation is strong. The mid-pack is generally well-settled and strong. At the base of the snowpack, weak facets may be found, particularly on shallow alpine slopes in the north of the region. Cornices are large and potentially fragile. Below treeline, the snow appears to be in a spring melt-freeze cycle.
