Lightning has been seen in volcanic eruptions, extremely intense forest fires , surface nuclear detonations, heavy snowstorms , and in large hurricanes . However, it is most often seen in thunderstorms . In fact, lightning (and the thunder that results) is what makes a thunderstorm. Lightning can occur from cloud-to-cloud, cloud-to-ground, cloud-to-air, or within a cloud.
Thunderstorms and lightning are most likely to develop on hot, humid days. If lightning is seen or heard, take protective action, such as seeking shelter, immediately. According to the National Weather Service (NWS) , a safe building has a roof, walls and a floor, such as a home, school, office building or a shopping center. They provide safety because lightning will usually travel through the wiring or the plumbing into the ground. Additional lightning safety tips are available from the NWS.
Please note: All lightning victims should have a medical examination, even if it does not appear to be needed. Call the local emergency department for help. Get to the victim as quickly as possible; it is not dangerous to touch someone who has just been hit by lightning. Check for injuries, but do not move a suspected spinal injury victim.
Lightning Safety Awareness Week is observed annually in June. The week emphasizes indoor safety and outdoor risk reduction tips, lightning medical facts, and the science of lightning. In 2010, it will take place from June 20 through June 26.
