Grand Canyon National Park:

Be Aware of Lightning Danger - date posted Sep 15, 2017

Summer storms in the southwest are often accompanied by potentially deadly lightning. Visitors walking and hiking in the park are reminded that if they can hear thunder, they should consider ending outdoor activities. If the sound of thunder follows a lightning flash within 30 seconds, seek shelter inside a building or vehicle. If this is not possible, move well away from high points such as ridges and the edge of the canyon. Do not seek shelter beneath tall trees.
