Varování, Le Haut des Roussottes

Severe thunderstorms are likely to cause severe damage locally. Lives and goods may be locally at stake. I keep away from trees and rivers. I take shelter in a solid building. I keep myself informed and I avoid traveling. I protect property exposed to the wind or which could be flooded. I avoid using my telephone and electrical appliances.

When planning outdoor activities, take into account any available protections and alternative routes. Avoid bodies of water and areas at risk of lightning strikes, such as mountain ridges, trees, pylons or towers as well as open terrain (e.g. clearings, football pitches). Secure outdoor objects and retract any awnings. Unplug electrical devices to protect against overvoltage. In open terrain, if lightning strikes nearby, assume a crouched position (with your feet together) with as little of your body as possible touching the ground (do not lie down flat). - Possible impacts: Lightning strikes. Breaking off of branches, toppling of individual trees. Landslides on steep slopes, sudden flash floods or debris flows in streams, flooding.
