Lightning occurs when the atmosphere is unstable. According to the National Oceanic and Atmospheric Administration’s (NOAA) Storm Prediction Center, lightning is an electrical spark that occurs between the ground, clouds, and air. When lightning begins to form, the air acts as an insulator between the negative and positive charges in the clouds and between the clouds and the ground.
As opposite charges accumulate, the insulating layer of air is broken down, resulting in a rapid discharge known as lightning. The bright flash seen in the sky during a thunderstorm is nature’s solution to temporarily balance the charged areas of the atmosphere. This cycle continues until the charges dissipate.
Lightning is the cause of loud thunder. The energy from lightning heats the air to about 27,700 degrees Celsius, causing the air to explode outward. The rapid pressure drop creates the sound of thunder.
If lightning is about to strike, a channel will gradually develop towards the ground. When it is less than 100 meters from the ground, tall objects such as trees and buildings will begin to emit electrical sparks to reach the channel. When the electrical spark connects with the downward channel, a strong current will flow down the object that generated the spark.
Lightning can create surges through plumbing and water systems, so when there is thunder, you should absolutely avoid bathing, washing dishes, or washing your hands.
To stay safe during thunderstorms with lightning, you need to avoid all conductive materials.
You should avoid going outside whenever you hear thunder. However, even when indoors, you still face the risk of being struck by lightning.
Sharing with Prevention, Mr. John Jensenius, a lightning safety expert from the National Weather Service, advises that to stay safe during thunderstorms with lightning, you need to avoid all conductive materials, including electrical wires, plumbing, and tap water.
In fact, not only metal pipes conduct electricity, but impurities in tap water can also have this capability. Therefore, plastic pipes cannot protect you 100%.
“Water conducts electricity, so if lightning strikes something in a puddle, a person standing near the puddle can easily be affected,” warns Mr. Jensenius. “Not only is bathing dangerous, but washing hands and dishes is also extremely risky. You should stop these activities when you hear thunder.”
