Avalanche Forecast
Regions: Glacier.
Weather Forecast
The heat continues, with freezing levels hovering around 3700m, intense sunshine, and calm to light winds at ridge-top. Clouds will begin to roll into the area tomorrow, with showers expected Thursday through Saturday. The freezing level will finally drop to ~2000m later on Saturday.
Snowpack Summary
The melt-freeze crust on slopes over 30* at tree-line and alpine elevations is thinner and weaker with the warm overnight temp's. This will break down rapidly with the record heat wave. Below tree-line, the snowpack is isothermal and loses all strength with the daytime warming. Northerly aspects in the high alpine still sport dry snow.
Avalanche Summary
A natural avalanche cycle late in the afternoon/evening yesterday saw deeper slabs failing, some to ground, on Tupper and MacDonald. Deep, wet slabs were also observed from S-facing aspects on Bagheera and Catamount. Expect glide-cracks to become more active, which are opening up on many slopes and can fail unpredictably.
