Protect Yourself From Severe Thunderstorms
Lightning Safety Awareness Week is June 21-27
In an annual coordinated effort with the National Weather Service (NWS), the Ohio Committee for Severe Weather Awareness is promoting June 21-27 as National Lightning Safety Awareness Week and encourages all Ohioans to know what to do before, during, and after thunderstorms and to practice severe weather safety and preparedness throughout the summer.
Since the inception of Lightning Safety Awareness Week in 2001, lightning fatalities in the U.S. have dropped from about 50 per year to an average of 30 or less per year. The NWS attributes this reduction to this weather safety campaign, to a greater awareness of lightning danger, and to people seeking safe shelter when thunderstorms develop.
As of June 15, 2020, three people have died after being struck by lightning in the United States this year. Last year, 20 people in a total of 13 states died from being struck by lightning. This includes two women from the Cincinnati area who tried to seek shelter from a storm under a tree.
There is no safe place outside when thunderstorms are in the area. But you can protect yourself, even if you’re caught outdoors when thunder and lightning storms are close by knowing lightning safety. The NWS and the Ohio Committee for Severe Weather Awareness (OCSWA) encourage Ohioans to have a safety plan not only for severe thunderstorms, but also for all weather events.
- Make listening or reading weather reports a part of planning your day. If the weather forecast calls for thunderstorms, you may need to postpone your trip or outdoor activity.
- “When thunder roars, go indoors!” Stop outdoor activities and seek a safe, enclosed shelter immediately.
- Remember the 30-30 Rule. After seeing lightning, start counting to 30. If you hear thunder before reaching 30, go indoors. Suspend outdoor activities for at least 30 minutes after hearing the last clap of thunder.
- If shelter is not available, crouch down low, with as little of your body touching the ground as possible. Lighting can cause electric currents along the top of the ground that can be deadly up to, and exceeding, 100 feet away.
- Avoid concrete floors and walls. Lightning can travel through metal wires or bars that may be embedded in concrete.
Prepare Before the Storm
- Know your area’s risk for thunder and lightning. Spring and summer are typical seasons for thunderstorms, but they can occur year-round, day or night.
- Sign up for your local emergency notification system or download a weather app. The Emergency Alert System and NOAA Weather Radio also provide emergency alerts.
- Cut down or trim trees that may be in danger of falling onto your home.
- Consider buying surge protectors, a lightning protection system, or lightning rods to protect your home, appliances, and electronic devices.
Survive During the Storm
- When you hear thunder or see lightning, move to safe shelter immediately, such as a substantial building, or a metal-topped vehicle (not a convertible), with the windows rolled up.
- Pay attention to weather reports and thunderstorm warnings.
- Get out and away from bodies of water. If boating, fishing or swimming, get to land and find a sturdy, grounded shelter or vehicle immediately.
- If indoors, avoid running water or using landline phones. Electricity can travel through plumbing and telephone lines.
- Never drive or walk through flooded roadways. Turn Around Don’t Drown ®. It takes just six inches of fast-moving water to knock an adult down, and about 12 inches of moving water can sweep away most vehicles.
Be Safe After the Storm
- Listen to local authorities and weather forecasts for storm watches or warnings or for any instructions regarding potential flash flooding.
- Wait 30 minutes after the last rumble of thunder before resuming outdoor activities.
- Watch for fallen power lines or broken tree limbs. Report hazards immediately.
Dublin’s Lightning Prediction System
The City of Dublin uses the Thor Guard Lightning Prediction System in several community parks including both community pools. The system predicts lightning strikes by measuring electrostatic charges on the ground and in the air. Thor Guard is a computerized system that can predict the probability of a lightning strike within 8-20 minutes before it will strike. The system is 97% accurate within a 2 mile radius.
When there is a potential for a lightning strike within the coverage area, a strobe light will turn on and a warning horn will sound with an uninterrupted 15-second blast. Immediately upon hearing or seeing these signals park and pool users should leave the area and seek appropriate shelter even if it does not appear that severe weather is imminent. Anytime lightning is visible, the best course of action is to seek shelter immediately. When the system senses conditions are safe, the strobe light will turn off and the horn will sound three short, four-second blasts. Then normal activity may then resume. The system operates 7 a.m. – 11 p.m. seven days per week from March through November.
The Thor Guard Lightning Prediction System is installed at five locations throughout the City. Lightning sensors and horns are located at Avery Park, Darree Fields, Emerald Fields and at both Community Pools. The lightning prediction sensor at each location operates independent of the others.
This system is designed to help you assess conditions. Neither the signal, nor the system is intended to guarantee that conditions are safe.
