Carry storm gear and a flashlight. During lightning storms avoid lone trees, cliff edges and high ridges. Return to your vehicle if possible. Watch weather conditions. Remember that climbing up is easier than climbing down.
Flash floods occur with amazing rapidity.
When caught in flash flood conditions, go to high ground. Do not attempt to drive through washes in flood. D Group members should stay together to avoid becoming lost. If you become lost, stay where you are. Make your location obvious to searchers.
