If you see lightning, count the number of seconds until you hear thunder. Divide the number of seconds by five to get the distance in miles (divide by 3 for kilometers) to the lightning strike or bolt.


"Positive" lightning bolts come from the upper parts of thunderstorms, striking up to several miles away. If you hear thunder, then lightning is near. There is NO SAFE PLACE OUTSIDE. Follow these safety rules:


Each year in the United States, lightning kills 20-30 people on average and injures 100s more. Tornadoes, hail, and wind gusts get the most attention, but only lightning can strike outside the storm itself. It is the first thunderstorm hazard to arrive and the last to leave.


Because lightning is one of the most capricious and unpredictable characteristics of a thunderstorm, no one can guarantee an individual or group absolute protection from it. However, knowing and following proven lightning safety guidelines can greatly reduce the risk of injury or death. Remember, YOU are ultimately responsible for your personal safety and should take appropriate action when threatened by lightning.


If lightning strikes the building, the plumbing and wiring will conduct the electricity more efficiently than a human body. If no buildings are available, then an enclosed metal vehicle such as an automobile, van, or school bus makes a decent alternative.






Convertible vehicles offer no safety from lightning, even if the top is "up". Other vehicles which are NOT SAFE during lightning storms are those which have open cabs, such as golf carts, tractors, and construction equipment.


A lightning safety plan should be an integral part of the planning process for any outdoor event. Do not wait for storm clouds to develop before considering what to do should lightning threaten! An effective plan begins LONG before any lightning threat is realized. You can't control the weather, so you have to work around it!


Detailed weather forecasts are accurate only out to seven days at best, but outdoor events are often planned many months in advance. Because of this limitation, every outdoor event coordinator should consider the possibility of lightning, especially if the event is scheduled during the late spring to early autumn months.


Studies have shown that most people struck by lightning are struck not at the height of a thunderstorm but before and after the storm has peaked. Most people are unaware of how far lightning can strike from its parent thunderstorm. Lightning can strike more than 10 miles away from the location of rainfall.


Therefore, if you can hear thunder, that IS YOUR WARNING that you are within striking distance. Seek safe shelter immediately. Remember these lightning safety rules: When thunder roars, go indoors and stay there until 30 minutes after the last clap of thunder. For those who are hearing impaired, remember See a Flash, Dash Inside. DO NOT wait for the rain to start before seeking shelter, and do not leave the shelter just because the rain has ended.


With common sense, you can greatly increase your safety and the safety of those around you. At the first clap of thunder, go to a large building or fully enclosed vehicle and wait 30 minutes after the last clap of thunder before you go back outside.


To minimize your personal risk of being struck by lightning when outside, Plan Ahead! Make sure you get the latest weather forecast at weather.gov before going out, and always know where safe shelter is if thunderstorms threaten.


Your behavior when thunderstorms are in the area determines your personal risk of being struck by lightning. The best way for you to protect yourself from lightning is to avoid the threat. You simply don't want to be caught outside in a storm.


Designate one of the members to monitor the weather via their smartphone using weather.gov, NWS Doppler radar, and other mobile weather apps so you will always have the latest forecast. Portable NOAA Weather Radios and AM/FM Radio can also be utilized. If thunderstorms are expected and you go ahead with your planned outdoor activity, have a lightning safety plan in place. Upon arriving on-site, determine how far away your shelter is in case lightning threatens. Remember to account for the time it will take to get to your safe location.


If you hear thunder, even a distant rumble, immediately move all to a safe place. Do not wait. You are in danger of being struck by lightning. Do not resume outdoor activities until 30 minutes after the last thunderclap.


Plan Ahead! Make sure the event organizers responsible for safety get a good weather forecast before the event begins, and make your lightning safety action plan known and used by all event organizers. Safety organizers should monitor the weather via their smartphones utilizing local NWS radar, weather.gov forecasts, and other mobile weather apps. Portable NOAA Weather Radios and AM/FM Radio can also be utilized.


Since it may take considerable time to evacuate people to a safe location, personal observation of the lightning threat may not be adequate, especially for fast moving lightning storms. Hand held or portable lightning detectors should be made available so that lightning can be observed at significant distances from the event site. Event organizers should know how long it will take to get people to safe shelter.


With large groups of people, safe locations must be identified beforehand, along with a means to route people to these locations. Event organizers might consider placing lightning safety tips on programs, score cards, etc. Lightning safety placards set up in strategic locations can be an effective means of raising awareness and communicating the lightning threat to the attending audience.


Although the odds of being struck by lightning each year are less than 1 in a million, some factors can put you at greater risk. Lightning most often strikes people who work outside or engage in outdoor recreational activities. Regional and seasonal differences can also affect your risk of being injured by lightning.


Being indoors does not automatically protect you from lightning. In fact, about one-third of lightning-strike injuries occur indoors. Here are some tips to keep safe and reduce your risk of being struck by lightning while indoors.


Lightning strikes may be rare, but they still happen, and the risk of serious injury or death is severe. Take thunderstorms seriously. Learn and follow the above safety rules to keep yourself safe from lightning.


A thunderstorm is classified as a severe thunderstorm when it contains large (at least one inch) hail and/or winds of 58 MPH or greater. If you can hear thunder, you are close enough to be affected by lightning. Lightning can strike up to 10 miles ahead of or trailing a storm. Thunderstorms can occur by themselves, in clusters, or in lines. The typical thunderstorm is 15 miles in diameter and produces heavy rain for 30 minutes to an hour.


Strengthen Your Home

Cut down or trim trees that may be in danger of falling on your home. Consider buying surge protectors, lightning rods or a lightning protection system to protect your home, appliances and electronic devices.


Education and prevention are the keys to lightning safety. This article will provide several prevention strategies and educational resources to help member institutions prepare to respond to a lightning hazard. Prevention should begin long before any athletically-related activity, event or practice by having an institutional lightning safety plan in place. The following steps are recommended by the NCAA and NOAA to mitigate risk of a lightning hazard:


Specific lightning safety guidelines have been developed with the assistance of lightning safety experts. Institutions should design a lightning safety plan that considers local safety needs, local venues (including access to those venues), weather patterns and storm types.


To estimate the distance between your location and a lightning flash, use the "Flash to Bang" method: If you observe lightning, count the number of seconds until you hear thunder. Divide the number of seconds by five to obtain the distance in miles. Example: If you see lightning and it takes 10 seconds before you hear the thunder, then the lightning is 2 miles away.


Because lightning can strike up to 10 miles from a storm, you should seek safe shelter as soon as you hear thunder or see lightning. Get to a safe location if the time between the lightning flash and the rumble of thunder is 30 seconds or less.


Many athletically-related activities occur outdoors and these activities may rely on coaches, officials, athletic trainers and athletics administrators to make safety decisions. Therefore, it is essential for everyone involved in intercollegiate athletics to understand the dangers of lightning, have a lightning safety plan in place, and follow the plan once thunder is heard or lightning is seen. Weather watchers, real-time weather forecasts and commercial weather-warning devices or services are all tools that can be used to aid in the monitoring and notification of threatening weather situations, decision-making regarding stoppage of play, evacuation and return to play.
