Don't park under isolated trees or overhangs, and avoid handling electrical conductors. If exposed to lightning outdoors, crouch down with your feet together, as lightning is attracted by anything sticking out, and do not lie down or lean against a wall.
Insulating the ground as much as possible with any insulating material, such as a roll of rope or a sleeping bag, is also an effective protective measure. To follow the evolution of this weather vigilance in real time, we recommend that you regularly consult the official Météo-France website or its dedicated mobile application.
