Description:
There is only a low danger of avalanching around the ski areas. Further back towards the main divide small slab avalanches could be triggered on steep unsupported terrain.above 2000m. Take care to assess local wind effects and the bond to underlying crusts, especially if the surface snow feels a little stiff and snow cover over the crust a bit deeper than average.

Current Snowpack Conditions

Current Snowpack Conditions
Up to 30 cms of recent snow lies over the june rain crust. On sheltered shady slopes a spell of mostly fine cold weather has facetted out surface layers to the point where they're now quite weak and sugary. Southerly 1/4 winds over the last few days have led to some windloading on lee slopes and in some places shallow windslab will lie over a weak crust facet sandwich. Exposed western aspects may be shallow, wind stripped, and rocky. The snow pack is mostly stable but pockets of reactive windslab could lie on steep slopes subject to recent windloading.
