Confidence

Moderate - Due to the number of field observations

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.
