Thunderstorm in forest
Generally we walk morning to afternoon and thunderstorms come most frequently at evening. Thanks to modern technology weather predictions are quite right so we know about bad weather a few hours before. If there is unexpected thunderstorm we seek for indoor shelter. If it is not possible we switch off the phones and search lowest point possible in the area. We avoid hilltops, high trees and rivers. We move by small steps or stay still and keep distance one from another. To increase safety get to low ground. Crouch down. If you have metal objects leave it more than 20 meters from people. Do not approach fences, antennas, poles, etc.
