What Can lightning penetrate?
Lightning forms between a storm cloud and the earth. Since a lightning bolt's objective is to reach the ground, it will pass through your home's structure, electrical wiring, or water pipes.
Lightning can jump through windows, so keep your distance from them during storms! The second way lightning can enter a building is through pipes or wires. If the lightning strikes utility infrastructure, it can travel through those pipes or wires and enter your home that way.
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.
The safest location during a thunderstorm is inside a large enclosed structure with plumbing and electrical wiring. These include shopping centers, schools, office buildings, and private residences.

The same is true for open garages, carports, or any shelter that isn't fully enclosed with a roof, walls, and a floor.
When You See Lightning, Count The Time Until You Hear Thunder. If That Is 30 Seconds Or Less, The Thunderstorm Is Close Enough To Be Dangerous – Seek Shelter (if you can't see the lightning, just hearing the thunder is a good back-up rule). Wait 30 Minutes Or More After The Lightning Flash Before Leaving Shelter.
It's no secret that the safest place to stay during a lightning storm is indoors. In fact, a home or other substantial structure like an office building serves as the best protection from a lightning strike. However, no residential home is immune to the threat of lightning strike damage.
But the odds of being struck by lightning in a given year are less than one in a million, and almost 90% of all lightning strike victims survive.
More often than not, thunderstorms strike late in the evening, at night or during the early hours of the morning.
Avoid hilltops and open areas. Lightning seeks the highest ground, so if indoor shelter is not available, crouching down in the nearest, lowest, unexposed point is a better bet. Distance yourself from tall objects. Never stand near tall structures — particularly metal ones — which can act as lightning rods.
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.
How long does thunder last for?
This can last between 30 minutes to an hour. Why do I care? If you see a thunderstorm coming, knowing what stage it is in could help you determine how much impact it will have on the area around you.
Anything that's plugged into an outlet in your home is at risk of suffering damage from an electrical surge during thunderstorms. If an electrical storm has been forecast, unplug your computer, laptop, and other devices, and consider unplugging appliances.
Like trees, houses, and people, anything outside is at risk of being struck by lightning when thunderstorms are in the area, including cars. The good news though is that the outer metal shell of hard-topped metal vehicles does provide protection to those inside a vehicle with the windows closed.
Stay away from anything that could conduct electricity such as radios, toasters, hairdryers and Unplug any electronic equipments before the thunderstorm arrives. This may also include fireplaces, radiators, stoves metal pipes, sinks, and phones. Stay away from window and doors and stay off verandas.
This shock wave can break the mirror, so some people cover the mirror because the cloth may act as a damping materials to the viberations and abosrb the sound energy which may prevent the mirror from shattering.
- Immediately get off elevated areas such as hills, mountain ridges, or peaks.
- Never lie flat on the ground. ...
- Never shelter under an isolated tree.
- Never use a cliff or rocky overhang for shelter.
- Immediately get out of and away from ponds, lakes, and other bodies of water.
Lightning is a dangerous yet often-overlooked weather phenomenon. Statistically, chances that someone is struck and killed by lightning is 1 in 1.9 million. For homes, the number is a surprising 1 in 200.
It can puncture a roof, sear the surrounding materials, and tear through attics. A powerful enough strike can tear off shingles and gutters, leaving the roof a disaster. Fire is another serious concern, says ABC KGUN9 News.
Lightning strikes cause house fires because the lightning causes a surge of electricity. The wave of electricity can cause sparks to fly in the air, which is then picked up by dry vegetation and other flammable materials. Lightning can also strike wires, creating electrical arcs that result in fires.
"The result is a shock wave that creates a sonic boom --like a jet exceeding the speed of sound – which can reverberate off of the ground and buildings. All of that energy can't just stop as soon as it hits something, so it will transfer into those objects and cause rumbling and shaking."
What state has the most lightning?
The state with the highest count of lightning in the United States in 2021 was Texas, amounting to a sum of 41,914,516 lightning events recorded. Texas always has higher lightning count than any other state, partly due to its size and location.
Most deaths after lightning strikes occur either because of primary cardiac arrest or hypoxia-induced secondary cardiac arrest.
Most deaths occur within one hour of injury and are due to fatal arrhythmia or respiratory failure. Up to 74% of survivors may have some form of permanent disability.
While lightning has been recorded to strike at a distance of 10 miles, the rule of thumb used for safety is a six mile distance. Thus, seeking shelter is recommended if the lightning is six miles away or less.
When lightning strikes, most of electrical discharge occurs near the water's surface. Most fish swim below the surface and are unaffected. Although scientists don't know exactly just how deep the lightning discharge reaches in water, it's very dangerous to be swimming or boating during a thunderstorm.
lightning rod, metallic rod (usually copper) that protects a structure from lightning damage by intercepting flashes and guiding their currents into the ground.
A direct hit from a lightning bolt is so powerful that it can split stone, brick, cinderblock, and concrete with ease.
Although every lightning strike is different, damage to the antenna, electrical system, rear windshield, and tires is common. The heat from a lightning strike is sufficient to partially melt the antenna of a vehicle and can cause what seems like a small explosion of sparks as tiny fragments of metal melt and burn.
The energy from a nearby lightning strike can travel through communication wires (such as phone, internet, or cable wires), directly from a utility pole into the home's electrical panel, or through conductive metal (such as plumbing or metal bars in the foundation) (NWS).
For homes, the number is a surprising 1 in 200. A number of things happen to people who are struck by lightning. Often, they suffer from third degree burns, burst ear drums, singed clothing and singed hair.
Does a roof protect you from lightning?
A metal roof can protect your house from both the heat of the lightning strike and the electrical current because of its non-combustible nature. A metal roof can protect your home from lightning damage better than other building materials.
Lightning can travel through plumbing. It is best to avoid all water during a thunderstorm. Do not shower, bathe, wash dishes, or wash your hands. The risk of lightning travelling through plumbing might be less with plastic pipes than with metal pipes.
Lightning strikes cause house fires because the lightning causes a surge of electricity. The wave of electricity can cause sparks to fly in the air, which is then picked up by dry vegetation and other flammable materials.

Typically, a sharp crack or click will indicate that the lightning channel passed nearby. If the thunder sounds more like a rumble, the lightning was at least several miles away. The loud boom that you sometimes hear is created by the main lightning channel as it reaches the ground.
