Lightning is a powerful electrical discharge that occurs during thunderstorms. It tends to strike taller objects like trees, because they provide a more direct path for the electrical current to reach the ground. When lightning hits a tree, the electrical energy can travel down the trunk and into the earth, posing a threat to anyone standing nearby.

There are several reasons why standing under a tree during a thunderstorm is dangerous: 1. If the tree is struck by lightning, the electricity can be transmitted through the roots and into the ground, causing harm to anyone nearby. 2. Lightning can cause the sap inside the tree to rapidly heat and expand, potentially causing the tree to explode or break apart, sending dangerous debris flying in all directions. This poses a significant risk to anyone in the vicinity. 3. Trees offer little protection from the rain, hail, and strong winds typically associated with thunderstorms. This can leave individuals vulnerable to other hazards during the storm.

Instead of seeking shelter under a tree in a thunderstorm, consider the following alternatives to protect yourself from lightning: 1. Move indoors: The safest place to be during a thunderstorm is inside a building. Make sure to stay away from windows and avoid using electronics connected to power outlets, as lightning can travel through electrical wiring. 2. Get inside a vehicle: If you are unable to find a building for shelter, get inside a hard-topped vehicle with the windows closed. The metal frame of the car can help to dissipate the electrical charge from a lightning strike. 3. Adopt the lightning crouch: If you are caught outside with no available shelter, minimize your contact with the ground by crouching down with your feet together, head tucked, and hands covering your ears. This position helps to minimize the risk of injury from ground currents and reduces your height to make you less likely to be struck by lightning directly. Always pay close attention to weather forecasts and plan accordingly to avoid being caught outdoors in a thunderstorm. If you hear thunder, remember the 30/30 rule: seek shelter if the time between the lightning flash and thunder is less than 30 seconds, and wait at least 30 minutes after hearing the last thunder before resuming outdoor activities.
