If you hear thunder or see lightning: When Thunder Roars, Go Indoors
- Stop all outdoor activities.
- Seek shelter in a substantial building or hard-topped vehicle.
- Avoid open high ground and isolated large trees.
- Avoid water (such as swimming pools, lakes, and rivers), beaches, and boats.
- Stay away from doors, windows, and metal objects such as pipes or faucets.
- Use the 30-30 rule for outdoor activity.
The 30-30 Rule
30 Seconds: Count the seconds between seeing lightning and hearing thunder. If this time is less than 30 seconds, lightning is still a potential threat. Seek shelter immediately.
30 Minutes: After the last lightning flash, wait 30 minutes before leaving the shelter.
If Someone is Struck by Lightning:
- Call 9-1-1. Provide directions and information about the lightning strike and victim(s).
- Give first aid. Do not delay CPR if the person is unresponsive or not breathing.
- If possible, move the victim to a safer place. Lightning can strike twice. Don’t become a victim.
