Cool temperatures over the weekend will reduce this problem but caution advised on slopes if hot sunny conditions are experienced.
Weather Forecast
A typical diurnal pattern is expected through the weekend with late afternoon freezing level limited to 2250m. A cooler day expected on Saturday with light winds and a mix of sun and clouds. Similar conditions on Sunday. Should be a beautiful weekend!
Snowpack Summary
A strong melt freeze crust will form Friday night after a very warm day. This crust will bridge a weak and isothermal snowpack on most tree-line and alpine slopes. This crust will break down with increasing temperatures and solar input. A persistent slab, 30 to 70cms thick, will be of greatest concern on Northerly aspects.
Avalanche Summary
No new avalanches observed at time of bulletin (15:30 hrs) but expecting continued solar and temperature triggered avalanches on all aspects and elevations.
