Each year, around 300 people, on average, are struck by lightning across the country. Sadly, around 30 of those are killed. The odds of being struck are 1 in 13,000 for an average lifespan.
Data compiled by the National Oceanic and Atmospheric Administration shows that over a 10 year period, Colorado had the third most lightning fatalities in the country. Colorado isn't a lightning "magnet" per se. Much of the southeastern US has much more lightning per year. However, the state is a dangerous lightning state due to our outdoor lifestyles.
Here are some things you may not know about lightning here in Colorado.
- El Paso has been the deadliest with 10 fatalities since 1980, then Larimer and Jefferson Counties with 9 and 8 respectively.
- The majority of fatalities and injuries are men.
- July is the most dangerous month of the year, followed by June.
- The majority of lightning strikes in Colorado occur from Mt Evans and Mt Bierstadt to Pikes Peak. Teller County is the state's most active lightning county.
Victims can be directly struck by lightning or can be injured/killed by the electrical current from the ground surrounding a nearby strike. A victim doesn't hold onto the current, so it is safe to touch him/her following the hit. Cardiac arrest is the most likely result, so contact 911 immediately. Those that do survive will likely have lifelong pain and neurological disorders.
NOAA lists the following bullet points for lightning safety while outdoors:
- Avoid open fields, the top of a hill or a ridge top.
- Stay away from tall, isolated trees or other tall objects. If you are in a forest, stay near a lower stand of trees.
- If you are in a group, spread out to avoid the current traveling between group members.
- If you are camping in an open area, set up camp in a valley, ravine or other low area. Remember, a tent offers NO protection from lighting.
- Stay away from water, wet items, such as ropes, and metal objects, such as fences and poles. Water and metal do not attract lightning but they are excellent conductors of electricity. The current from a lightning flash will easily travel for long distances.
And, some tips for indoors during lightning:
- Stay off corded phones. You can use cellular or cordless phones.
- Don't touch electrical equipment such as computers, TVs, or cords. You can remote controls safety.
- Avoid plumbing. Do not wash your hands, take a shower or wash dishes.
- Stay away from windows and doors that might have small leaks around the sides to let in lightning, and stay off porches.
- Do not lie on concrete floors or lean against concrete walls.
- Protect your pets: Dog houses are not safe shelters. Dogs that are chained to trees or on metal runners are particularly vulnerable to lightning strikes.
- Protect your property: Lightning generates electric surges that can damage electronic equipment some distance from the actual strike. Typical surge protectors will not protect equipment from a lightning strike. The American Meteorological Society has tips for protecting your electronics from lightning. Do not unplug equipment during a thunderstorm as there is a risk you could be struck.
Understanding these lightning myths and facts could save your life:
Myth: If you're caught outside during a thunderstorm, you should crouch down to reduce your risk of being struck. Fact: Crouching doesn't make you any safer outdoors. Run to a substantial building or hard topped vehicle. If you are too far to run to one of these options, you have no good alternative. You are NOT safe anywhere outdoors.
Myth: Lightning never strikes the same place twice. Fact: Lightning often strikes the same place repeatedly, especially if it's a tall, pointy, isolated object. The Empire State Building is hit an average of 23 times a year
Myth: If it’s not raining or there aren’t clouds overhead, you’re safe from lightning. Fact: Lightning often strikes more than three miles from the center of the thunderstorm, far outside the rain or thunderstorm cloud. “Bolts from the blue” can strike 10-15 miles from the thunderstorm.
Myth: Rubber tires on a car protect you from lightning by insulating you from the ground. Fact: Most cars are safe from lightning, but it is the metal roof and metal sides that protect you, NOT the rubber tires. Remember, convertibles, motorcycles, bicycles, open-shelled outdoor recreational vehicles and cars with fiberglass shells offer no protection from lightning. When lightning strikes a vehicle, it goes through the metal frame into the ground. Don't lean on doors during a thunderstorm.
Myth: A lightning victim is electrified. If you touch them, you’ll be electrocuted. Fact: The human body does not store electricity. It is perfectly safe to touch a lightning victim to give them first aid. This is the most chilling of lightning Myths. Imagine if someone died because people were afraid to give CPR!
Myth: If outside in a thunderstorm, you should seek shelter under a tree to stay dry.
Fact: Being underneath a tree is the second leading cause of lightning casualties. Better to get wet than fried!
Myth: If you are in a house, you are 100% safe from lightning.
Fact: A house is a safe place to be during a thunderstorm as long as you avoid anything that conducts electricity. This means staying off corded phones, electrical appliances, wires, TV cables, computers, plumbing, metal doors and windows. 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.
Myth: If thunderstorms threaten while you are outside playing a game, it is okay to finish it before seeking shelter. Fact: Many lightning casualties occur because people do not seek shelter soon enough. No game is worth death or life-long injuries. Seek proper shelter immediately if you hear thunder. Adults are responsible for the safety of children.
Myth: Structures with metal, or metal on the body (jewelry, cell phones,Mp3 players, watches, etc), attract lightning. Fact: Height, pointy shape, and isolation are the dominant factors controlling where a lightning bolt will strike. The presence of metal makes absolutely no difference on where lightning strikes. Mountains are made of stone but get struck by lightning many times a year. When lightning threatens, take proper protective action immediately by seeking a safe shelter â€“ don’t waste time removing metal. While metal does not attract lightning, it does conduct it so stay away from metal fences, railing, bleachers, etc.
Myth: If trapped outside and lightning is about to strike, I should lie flat on the ground. Fact: Lying flat increases your chance of being affected by potentially deadly ground current. If you are caught outside in a thunderstorm, you keep moving toward a safe shelter.
Myth: lightning flashes are 3-4 km apart Fact: Old data said successive flashes were on the order of 3-4 km apart. New data shows half the flashes are about 9 km apart. 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). In the past, 3 to 5 km (2-3 miles) was as used in lightning safety education."

Myth: A High Percentage of Lightning Flashes Are Forked. Fact: Many cloud-to-ground lightning flashes have forked or multiple attachment points to earth. 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. Many lightning detectors cannot acquire accurate information about these multiple ground lightning attachments.

Myth: Lightning Can Spread out Some 60 Feet After Striking Earth. Fact: Radial horizontal arcing has been measured at least 20 m. from the point where lightning hits ground. Depending on soils characteristics, safe conditions for people and equipment near lightning termination points (ground rods) may need to be re-evaluated.
