In sintesi

Iceclimbers need to factor in the possibility of afternoon loose wet slides in your plans. Temperatures are cooling off the next few days but skies will remain sunny maintaining short wave energy input onto the snow surface.

    A 2m fracture line was observed today. Despite these observations being sporadic, they are still occurring and should remain on your radar and factor into your decisions. They are limited to alpine features above 2600m and running far.
