To reduce the chance of being hit by an avalanche on Mont Blanc, choose your travel time carefully. More often than not avalanches come off after heavy snowfall, when new snow falls on the already mortified old one. The risk is especially great when snowfall occurs at a low temperature. It is not recommended to send to the mountains during high winds. Increase the risk of avalanche and abrupt weather changes.
The probability of an avalanche going off varies also from month to month. December and January are the safest on Mont Blanc, the most dangerous — February and March. In February and March, repeated snow periodically lurches and forms so-called “snow boards”, which are then again covered with snow. A thick layer of snow is overchristilled into large ice needles, on which new snow mass accumulates. All this at any moment can break away and roll down, sweeping away everything in its path.
Before you go to Mont Blanc, it is not unnecessary to know the depth of the snow cover. The lowest I degree of avalanche risk is set at the depth of snow up to 30 cm, II degree – from 30 to 50 cm, III – from 50 to 70 cm, IV – from 70 to 100 cm. The highest degree of avalanche risk when going into the mountains is not recommended – the thickness of snow cover from 120 cm.
The easiest way to protect yourself from being hit by an avalanche on Mont Blanc is not to go out into the mountains immediately after heavy snowfall, try to avoid small ravines, valleys with steep slopes and hollows. To travel to Mont Blanc is a safe organized group accompanied by an experienced climber. Try not to deviate from the paved route. As a rule, such routes are regularly checked by rescuers for safety, thanks to which, the probability of getting under the avalanche is minimized.
