There is a continuing HIGH avalanche risk for Monday February 1st over much of the Northern Alps. Particularly the Haute-Savoie and the interior ranges of the Savoie and Isere above 2000 to 2200 meters.
There was fresh snow all day on Sunday in the Northern Alps with a snowline that rose gradually from 1800 to 2000 meters. At altitude the snow was often accompanied by strong winds. In the two Savoies 50 to 60cm of fresh snow fell at 2500 meters, locally 80cm on the Mont Blanc, 30 to 40 cm in the Isere.
On Monday the danger of a skier or skiers triggering an avalanche in the recent snow layers is a concern, especially in the two Savoies above 2000 to 2000 meters and in the Isère mountain ranges above 2500m .
In addition, humidification of the snowpack will continue following the end of Sunday's rain and with Monday's extraordinary rise in temperatures (0° C isotherm to 4000m). There will be natural wet snow slides from mid to high altitudes on sunny slope aspects sometimes taking the entire snowpack.
