Myth: Lightning Can Spread out Some 60 Feet After Striking Earth.įact: Radial horizontal arcing has been measured at least 20 m. Proceedings 1998 Int'l Lightning Protection Conference, Birmingham UK, Sept. Source: Termination of Multiple Stroke Flashes Observed by Electro- Magnetic Field: 1998, Ishii, et al. Many lightning detectors cannot acquire accurate information about these multiple ground lightning attachments. Tests carried out in the US and Japan verify this finding in at least half of negative flashes and more than 70% of positive flashes. Myth: A High Percentage of Lightning Flashes Are Forked.įact: Many cloud-to-ground lightning flashes have forked or multiple attachment points to earth. In the past, 3 to 5 km (2-3 miles) was as used in lightning safety education.' Source: Separation Between Successive Lightning Flashes in Different Storms Systems: 1998, Lopez & Holle, from Proceedings 1998 Intl Lightning Detection Conference, Tucson AZ, November 1998. The National Severe Storms Laboratory report concludes: 'It appears the safety rules need to be modified to increase the distance from a previous flash which can be considered to be relatively safe, to at least 10 to 13 km (6 to 8 miles). New data shows half the flashes are about 9 km apart. If you are caught outside in a thunderstorm, you keep moving toward a safe shelter.įact: Old data said successive flashes were on the order of 3-4 km apart. Myth: If trapped outside and lightning is about to strike, I should lie flat on the ground.įact: Lying flat increases your chance of being affected by potentially deadly ground current. While metal does not attract lightning, it does conduct it so stay away from metal fences, railing, bleachers, etc. When lightning threatens, take proper protective action immediately by seeking a safe shelter and don’t waste time removing metal.

Natural objects that are tall and isolated, but are made of little to no metal, like trees and mountains get struck by lightning many times a year. The presence of metal makes absolutely no difference on where lightning strikes. Myth: Structures with metal, or metal on the body (jewelry, cell phones,Mp3 players, watches, etc), attract lightning.įact: Height, pointy shape, and isolation are the dominant factors controlling where a lightning bolt will strike. Adults are responsible for the safety of children. Seek proper shelter immediately if you hear thunder. No game is worth death or life-long injuries. Myth: If thunderstorms threaten while you are outside playing a game, it is okay to finish it before seeking shelter.įact: Many lightning casualties occur because people do not seek shelter soon enough.

Windows are hazardous for two reasons: wind generated during a thunderstorm can blow objects into the window, breaking it and causing glass to shatter and second, in older homes, in rare instances, lightning can come in cracks in the sides of windows.

This means staying off corded phones, electrical appliances, wires, TV cables, computers, plumbing, metal doors and windows. Myth: If you are in a house, you are 100% safe from lightning.įact: A house is a safe place to be during a thunderstorm as long as you avoid anything that conducts electricity. Myth: If outside in a thunderstorm, you should seek shelter under a tree to stay dry.įact: Being underneath a tree is the second leading cause of lightning casualties. Imagine if someone died because people were afraid to give CPR! When tending to a lightning victim, be aware of the continued threat for lightning, and move yourself and the victim to a safe location as soon as it is possible. This is the most chilling of lightning Myths. It is perfectly safe to touch a lightning victim to give them first aid. If you touch them, you’ll be electrocuted.įact: The human body does not store electricity.

“Bolts from the blue” can strike 10-15 miles from the thunderstorm. Myth: If it’s not raining or there aren’t clouds overhead, you’re safe from lightning.įact: Lightning often strikes more than three miles from the center of the thunderstorm, far outside the rain or thunderstorm cloud. The Empire State Building is hit an average of 23 times a year Myth: Lightning never strikes the same place twice.įact: Lightning often strikes the same place repeatedly, especially if it's a tall, pointy, isolated object. See our safety page for tips that may slightly reduce your risk. If you are too far to run to one of these options, you have no other good alternative. Run to a substantial building or hard topped vehicle. Myth: If you're caught outside during a thunderstorm, you should crouch down to reduce your risk of being struck.įact: Crouching doesn't make you any safer outdoors.
