Avalanche Summary

No avalanches have been reported since the warming ended on Tuesday. Use caution around cornices, especially during periods of sunshine.

Snowpack Summary

Up to 10 cm of new snow overlies a widespread surface crust formed during recent warm, sunny conditions. Dry snow is now limited to north aspects in the alpine between 2000 and 2500 m and above.

Below the surface crust, the snowpack is generally well consolidated. A widespread mid-March melt-freeze crust is buried 10 to 80 cm deep, varying with aspect and elevation.

The lower snowpack remains strong and well-bonded.
