Summary

Weather Forecast

Clear, cold and dry weather is expected over the weekend. Expect light northerly winds, and highs of -8. Westerly flow on Monday will bring flurries and rising freezing levels.

Snowpack Summary

Above 1800m 40cm of unsettled snow overlies a series of crusts. This storm snow is being transported by Northerly winds, forming slabs in exposed areas. Stability tests at 2100m on a S aspect found moderate resistant planar shears above the crust.

Avalanche Summary

Recent avalanche activity has been limited to sluffing off of steep slopes.
