Avalanche danger forecast for

AVALANCHE DANGER  

0░C at 3000 m: very hot on the sunny slopes and increased instability from mid-morning.

Tuesday 2/23/2021
  

<3000 m

   

Avalanche problemswet snow.

Fair to good night refreeze. Stable snowpack in the early morning, with strong humidification on the steep sunny slopes with increased instability in the warmest and afternoon hours.

Triggered avalanches
Below 3000 m, on S very steep slopes, it is possible to trigger small/medium surface avalanches of wet a nd very wet snow, especially near rocky outcrops. Above 2800 m there is the possibility of detaching some rare small and medium-sized wind slabs, especially on very steep slopes. The accumulations are mostly clearly visible and therefore can be avoid. They are more common in the west.

Natural avalanches
Below 3000 m possible sluffs and small/medium avalanches of wet/very wet snow from rocky bars and along gullies on very steep sunny slopes. Possible isolated avalanches below 2500 m on the usual extremely steep grassy slopes.áSome background avalanches at lower altitudes.



AVALANCHE DANGER TREND  Wednesday 24:    Thursday 25:  

Constant.áSpring conditions, with increased danger during the hottest hours of the day.


GENERAL CONDITION
updated to 2/22/2021
  Please note: in theáclosed ski-resorts areas slopesáare not managed and must therefore be considered as potentially avalanche terrain

Snow cover and snowpack
In general, snow cover is better at mid-mountain altitudes and is more uneven above 2500 m, with eroded bumps, full hollows and valleys. The center of the valley and the areas of Gran Paradiso have less snow.
Above 2300 m at all aspects there are widespread persistent weak basal layers, not active at the moment.
Possible weak layer just above or just below the sand freeze crust.
Good freezing in the morning and poor humidification during the day due to high cloud cover

Avalanches observed over the last 24h
Sluffs of damp/wet snow above 2300 m on the sunny slopes.

Skiability
Steep southern slopes: up to 2800-3000 m spring snow, frozen in the morning (the use of knives is recommended), then gradually softer.
North slopes, especially in the west of the Region: still powdery or chalky snow.
Other aspects and altitudes: wind or refreeze crusts, difficult to ski.
