If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you’ll get the distance in miles to the lightning: 5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close. Keep in mind that you should be in a safe place while counting.
What is the 30 30 rule for lightning?
Don’t forget the 30-30 rule. After you see lightning, start counting to 30. If you hear thunder before you reach 30, go indoors. Suspend activities for at least 30 minutes after the last clap of thunder.
How far does a thunderstorm travel?
Lightning can travel 10 to 12 miles from a thunderstorm. This is often farther than the sound of thunder travels. That means that if you can hear thunder you are close enough to a storm to be in danger of being struck by lightning.
How far away is a lightning strike if you hear the thunderclap?
When you are out in the great outdoors and have no internet access, you can calculate the distance of a storm using the simple 3-second rule: Just count the seconds between when you see the lightning strike and when you hear the thunder clap and divide this number by three.
How far away is lightning km?
For metric-system conversions, follow this method: Sound travels at about 340 m/s, so multiply the number of seconds you counted by 340, and you’ll know how many meters away lightning struck. A three-second count, then, would place the lightning strike about 1,020 m away, or roughly 1 km.
Is it OK to have your AC on during thunderstorm?
Though it’s tempting to rely on your air conditioner, you shouldn’t run your unit during a thunderstorm. Not only does running your AC during a storm put your system at risk, but it can also put your safety at risk.

Why is thunder so loud?
A big noise Why is thunder so loud? It’s because the amount of electrical energy that flows from the cloud to the ground is so enormous: it’s like a very big waterfall of electricity. The louder the sound that you hear, the closer you are to the lightning. Light travels through air much faster than sound.

How loud is lightning right next to you?
A clap of thunder typically registers at about 120 dB in close proximity to the ground stroke. This is 10 times louder than a garbage truck or pneumatic jackhammer drill. By comparison, sitting in front of speakers at a rock concert can expose you to a continuous 120+ dB level.
Why are you safe in a car during a lightning storm?
Cars are safe from lightning because of the metal cage surrounding the people inside the vehicle. This may sound counter-intuitive because metal is a good conductor of electricity, but the metal cage of a car directs the lightning charge around the vehicle occupants and safely into the ground.
How Far Can lightning be seen at night?
At night, it is possible to see the flashes of lightning from very far distances, up to 100 miles (160 kilometres), but the sound does not carry that far.
How loud is lightning up close?
A clap of thunder typically registers at about 120 dB in close proximity to the ground stroke. This is 10 times louder than a garbage truck or pneumatic jackhammer drill. By comparison, sitting in front of speakers at a rock concert can expose you to a continuous 120+ dB level.
Is a bullet faster than lightning?
That is faster than a bullet fired from an assault rifle- 1000 metres per second.

No. Lightning can travel through plumbing. It is best to avoid all water during a lightning storm. Do not shower, bathe, wash dishes, or wash your hands.
How fast is the speed of thunder?
Lightning travels at the speed of light, about 186,000 miles per second. This means that you see lightning pretty much when it happens. When lightning strikes, a noise is made which we call thunder. Thunder travels much slower, at the speed of sound, about 1088 feet per second.
Can lightning strike a car?
A typical cloud-to-ground, actually cloud-to-vehicle, lightning strike will either strike the antenna of the vehicle or along the roofline. The lightning will then pass through the vehicle’s outer metal shell, then through the tires to the ground.
How many people get struck by lightning each year?
About 240,000 incidents regarding lightning strikes happen globally each year. According to National Geographic, annually about 2,000 people are killed worldwide by lightning.
Can I use a ceiling fan during a thunderstorm?
Just stay several feet away from it and you should be fine. One of the wires that connects to the fan is a ground wire. Any dangerous voltage that gets into a table fan, more than likely will take that ground wire to the earth, away from anyone several feet away from it.
Can you poop during a thunderstorm?
DO NOT POOP During A Thunderstorm. The plumbing company said this is just as rare as getting struck by lightning yourself. Do not shower, bathe, wash dishes, or wash your hands.
Can I pee during a thunderstorm?
Very hard, perhaps impossible, to kill yourself by peeing on high-voltage things. A toilet is probably as safe a place as any in a lightning storm, if you’re not touching metal. If you have metal plumbing instead of PVC, lightning can follow the pipes through your walls and give you a good (perhaps fatal) jolt.
Can I cook during a thunderstorm?
Nope, Don’t Do the Dishes If your house or plumbing isn’t properly grounded, the electricity from a lightning strike can move through pipes and water, which can shock you.
Why does thunder shake your house?
Why does the house shake when there is a thunder storm? Your house will shake depending the closeness of the lightning. Thunder is a sonic boom that comes from the rapid heating of the air around a lightning strike. Sonic booms cause massive shaking to nearby objects (your house).
What was the loudest thunder ever recorded?
The explosion was loud enough that this level of noise was recorded many miles away from the site of the blast. A sound of 174 decibels was recorded by barometers 100 miles from Krakatoa. That meant anyone within an 100 mile radius of Krakatoa had a chance of being literally deafened by this sound.
Why do thunderstorms only happen in the summer?
When warm moist air is unstable, it rises and expands. Thunderstorm development is so common on summer afternoons because of this intense daytime heating as well as the high humidity, thus providing the moisture, the instability, and the warm temperatures needed to cause the air to begin rising.
