If you hear thunder, seek a substantial building or an enclosed hard-topped vehicle. Wait at least 30 minutes after the last thunder before going back outside.
Before: make the plan
- Check forecasts before outdoor activities. Pick a real shelter and allow enough time to reach it.
- Choose who will monitor conditions and call a stop to an outdoor event.
- Secure loose outdoor items before the storm arrives, without putting yourself in danger.
During: protect people
- Leave water, exposed ground, and isolated trees. Open shelters, tents, and picnic pavilions do not provide reliable lightning protection.
- Inside, avoid corded electrical equipment and contact with plumbing during the storm.
- Watch for separate hazards such as flash flooding, hail, and damaging wind.
After: recover carefully
- Keep waiting until 30 minutes have passed since the last thunder.
- Avoid downed wires and damaged trees. Call emergency services for anyone struck by lightning; victims do not retain an electrical charge.
