Quick changes of weather and risks


In altitude, weather is uncommonly unstable and evolves quickly weather (snow, cold, fog, wind) and conditions changes (ice, frost, snow).It is important to be able to recognize the warning signs and to know when to retreat.

Clouds development is extremely fast and may cause severe orientation difficulties.

Thunderstorms are frequent, more surprising and more dangerous than on the valley floor. Fog and poor visibility, wind bursts (up to 150km/h at the top), put at risk the pace and lightning is a major danger.
