What Not to Do During a Thunderstorm

Thunderstorms are electrical storms characterized by lightning and thunder, often accompanied by strong winds, heavy rain, and sometimes hail. While typically localized, all thunderstorms are dangerous due to lightning. Understanding actions to avoid is important for safety during these unpredictable events.

What Not to Do Outdoors

Remaining outdoors during a thunderstorm significantly increases risk. Avoid open fields, as you could become the tallest object, making you more susceptible to a lightning strike. Do not seek shelter under isolated tall objects like trees or poles, as lightning frequently strikes the tallest point in an area, and currents can travel through them. Metal structures such as fences, bleachers, or golf clubs are also unsafe because metal conducts electricity efficiently, posing an electrocution risk if lightning strikes nearby.

Engaging in recreational activities near or on water bodies like lakes, pools, or oceans during a storm is particularly hazardous. Water is an excellent conductor of electricity, and a lightning strike can spread its charge across the surface, injuring anyone in the water. Get out of and away from all water immediately. If no safe building is available, a hard-topped vehicle offers better protection.

What Not to Do Indoors

While indoors, certain activities can still expose you to lightning’s dangers. Do not bathe, shower, wash dishes, or use any plumbing during a thunderstorm. Lightning can travel through pipes and water, creating a path for electrical current and increasing electrocution risk. Similarly, avoid using corded phones and touching electrical appliances like computers or televisions, as lightning can travel through electrical systems and wiring. Unplugging these devices before a storm arrives can protect them from power surges.

Stay away from windows and doors. Strong winds and hail can cause debris to fly or windows to shatter, posing a physical threat. Additionally, porches and garages with open access do not offer adequate protection from lightning and should be avoided. Concrete floors and walls may contain metal wires or bars that can conduct electricity, so avoid leaning on or lying on them.

What Not to Do While Driving

Driving during a thunderstorm presents specific hazards that require caution. Avoid driving through flooded roads or large puddles, as water depth can be deceptive and lead to hydroplaning. Even shallow water can stall a vehicle or sweep it away. Never attempt to drive through moving water, as just six inches can cause a car to lose control, and two feet can carry most vehicles away.

Stopping under overpasses or large trees for shelter is also ill-advised. Overpasses offer no protection from lightning and can become traps if flooding occurs. Trees are lightning targets, and falling branches pose a significant risk from strong winds. If lightning strikes your vehicle, avoid touching its metal frame, radio, or anything connected to the outside. Stay inside the vehicle with windows rolled up until the storm passes.
