Summary

Weather Forecast

The weather is stable with warm temperatures, light to moderate winds from the south west and minimal amounts (up to 2cm) of snow forecasted for the next 2 days.

Snowpack Summary

The snowpack is highly variable throughout the forecast region. In the south the snowpack continues to settle as a result of the warm temperatures, and some drifting and snow transport is resulting from steady moderate winds from the south west.

Avalanche Summary

Warm temps have triggered a few small storm / wind slab avalanches at TL and BTL within the past 24h in the south of the forecast region. No new avalanches were observed in the north of the forecast region.
