This problem primarily remains on alpine slopes as much of the lower snowpack has either melted or is now isothermal.
Weather Forecast
The heat wave ends!! The freezing level is expected to drop below 3000 m on Friday afternoon along with 12 mm of rain. The rain will turn to snow (5 cm) on Friday night. Seasonal temperatures with showers expected through the weekend.
Snowpack Summary
Isothermal conditions exist well into the alpine even on North aspects due to prolonged +3500m freezing level. No overnight recovery expected on Thursday night. The persistent slab problem still exists on north facing alpine slopes. Expect a very weak snowpack everywhere else.
Avalanche Summary
No recent observations however expecting continued loose wet and wet slab avalanches especially with forecasted rain on Friday.
