Touchy soft slabs can likely be found in wind loaded features or around convexities.
Confidence
Moderate - Due to the number of field observations
Weather Forecast
Thursday: cloudy with sunny periods, light west winds becoming southeasterly, freezing levels between 800m and 1200m. Friday: mainly clear and dry with light southerly winds and a freezing level of around 500m. Saturday: the next storm is expected to bring 5cm through the day with slight to moderate south winds and a freezing level of 1000m.
Avalanche Summary
No new avalanche have been reported since Tuesdays storm.
Snowpack Summary
Up to 15cm of new snow overlies a crust on steep solar aspects, or a layer of surface hoar on sheltered and shady slopes at all elevations. Moderate to strong southwest through south east winds have been loading lee features. 10 to 15 cm below this is a second buried weak layer again consisting of a melt-freeze crust on solar aspects in the alpine or well-developed surface hoar in sheltered areas at treeline and lower elevations. Deeper still, the mid and lower snowpack is generally strong, with the exception of shallow snowpack areas that may be more faceted. Bellow 1400m rain may have saturated the upper snowpack. Moderate southerly winds have formed soft slabs in lee features at treeline and in the alpine.
Problems
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
