A group of 10 children and adults were struck by lightning while taking cover under a tree near a soccer field. Regardless of the location there is no safe place outdoors during a thunderstorm. If you hear lightning or see thunder seek shelter immediately in a building with a roof, walls, doors, and windows. If no building is available seek shelter in a vehicle with the doors closed and window rolled up. If no building or vehicle is available move to lower risk areas, spread out, stay low, minimize contact with the ground, and hope for the best.
