As National Lightning Safety Awareness Week approaches, the Idaho Office of Emergency Management (IOEM) urges all Idahoans to stay informed and take steps to protect themselves from the dangers of lightning. This year’s awareness week runs from June 22 through June 28, 2025.

Lightning is a powerful and often underestimated natural event. According to the National Weather Service, lightning strikes kill an average of 20 people each year in the United States and injure many more. Although most lightning victims survive, people struck by lightning often report a variety of long-term, debilitating symptoms.

Lightning also poses significant risks to property and the environment. In Eastern Idaho, nearly half (47%) of wildfires between 2000 and 2020 were caused by lightning. These fires often occur during dry seasons, increasing risk and danger.

The best way to stay safe during a thunderstorm is to plan ahead. There is no safe place outside during a thunderstorm, so taking action early is key.

Safety Tips Before, During, and After Thunderstorms:

Before Thunderstorms and Lightning:

• Know Your Risk: Thunderstorms can happen year-round and at any hour. Be aware of your area’s risks and create an emergency plan.
• Stay Informed: Sign up for community warning systems and listen to Emergency Alert System (EAS) and NOAA Weather Radio alerts. Be sure to also follow regional NWS offices, local and state emergency management offices, and local first responders on social media for daily updates.
• Prepare Your Property: Trim trees that might fall on your home and consider installing surge protectors, lightning rods, or a lightning protection system.

During Thunderstorms and Lightning:

• When Thunder Roars, Go Indoors: Seek shelter in a building immediately. Remain inside for at least 30 minutes after hearing the last sound of thunder.
• Use Vehicles as Shelter: If no buildings are accessible, a hard-topped metal vehicle with windows rolled up can offer protection.
• Indoor Safety: Avoid using plumbing or landline phones, as electricity can travel through these systems. Do not touch anything that is plugged into an electrical outlet.
• Water Safety: If swimming, boating, or near a body of water, move to land and seek shelter immediately. If a car is the only option, stay inside but avoid touching anything metal.
• Flood Safety: Avoid flooded roadways. Remember, “Turn Around Don’t Drown” – just six inches of fast-moving water can knock you down, and one foot can sweep away your vehicle.
• Lightning Victims: If someone is struck by lightning, call 911 immediately. Lightning victims do not carry an electrical charge and are safe to touch.

After Thunderstorms and Lightning:

• Stay Updated: Listen to authorities and weather forecasts to determine when it is safe to go outside. Wait at least 30 minutes after the last sound of thunder.
• Report Hazards: Watch for downed power lines and fallen trees and report them to the appropriate authorities.

IOEM encourages everyone to create and review safety plans and educate family members about the precautions to take before, during, and after a thunderstorm. By staying informed and prepared, we can build a safer, more resilient Idaho.
