Wet avalanches are now more frequent on N to NE aspects as snowpack continues to deteriorate.
Deep Persistent Slabs

This problem primarily remains on alpine slopes as much of the lower snowpack has either melted or is now isothermal.
Weather Forecast
Cloudy conditions with showers on Sunday. Freezing levels staying above 2500m then falling to ~2000m by Monday.
Snowpack Summary
A very weak snowpack with isothermal conditions well into the alpine on all aspects due to prolonged +3000m freezing level. The persistent slab problem still exists on north facing alpine slopes in specific locations. Expecting a weak overnight recovery above 2500m.
Avalanche Summary
Widespread loose wet and wet slab avalanches from size 2-3 observed along the Parkway on Saturday, many initiated by cornice failure. Glide cracks appearing on steep NE terrain. The end of the 2016 ski season is nigh!!
