Different Types of Avalanches

It is vital that skiers/snowboarders can acknowledge the first indications of an avalanche, and that they understand what to expect when they take place. There are 3 unique forms of avalanches: wind slab, powder and wet snow.


The powder avalanche can potentially be unbelievably detrimental, although they tend to be relatively rare. Sometimes they can start out small, however they can build up in proportions together with power as they trigger other volatile areas in their course. Powder avalanches can reach speeds as much as 250mph, at times becoming airborne and capable of uprooting trees or destroying small structures.

Wet Snow

When top snow melts, it can penetrate through the snow pack to weaken lower tiers and subsequently eradicate binding to the mountain surface. As the snow pack becomes wetter, it increases in weight until eventually it can not sustain itself. Those who become trapped in this sort of avalanche are often unable to survive, as a result of insufficient oxygen. Wet snowfall avalanches turn into a particular issue during hot springtime days, or on southern facing ski slopes.

Wind Slab

Wind is generally a major indicator of how probable an avalanche is to manifest during any period. The less wind, the more probable it is that snow will be distributed evenly. The more powerful the wind flow, the more dangerous these drifts will likely grow to be. With long periods of sunlight as well as severe winds, huge volumes of snow can develop on top of lee slopes and become packed into a huge thick bulk. Whilst they are unlikely to form on especially steep ski inclines, they can. When they do, they can become especially lethal; triggered by something as imperceptible as an increase in environments. Wind slabs are most likely to slip when it is windy, as extra snow is deposited on top of a potential wind slab, the load of it leads it to develop into an avalanche.

Awareness and Safety

You should know of the possible risks whenever skiing/snowboarding off piste, and you need to make sure you acquaint yourself with the emergency procedures and equipment required to assure a safe experience. So off piste VIP ski lessons Chatel (as an example) are at all times worth considering.
