Last week, we talked about how often Cobb County experiences lightning and why it’s important to stay informed. Now, let’s dive into what you should do when you're caught outdoors in a storm.

The "30-30" Rule

A good rule of thumb for lightning safety is the "30-30" rule:

1. Count the seconds between a lightning flash and the sound of thunder. If it’s 30 seconds or less, the storm is dangerously close, and you need to seek shelter immediately.
2. Wait at least 30 minutes after the last thunderclap before resuming outdoor activities.

Think of it this way: If you can hear thunder, you’re close enough to be struck by lightning. It’s like playing with fire—don’t wait until you feel the heat to move away!

Finding Safe Shelter

If you’re outside and a storm rolls in, here’s where you should and shouldn’t go:

✅ Safe Places:

• A substantial building with plumbing and electricity (homes, businesses, schools)
• A hard-topped metal vehicle with the windows closed

❌ Unsafe Places:

• Open fields or hilltops
• Under trees or picnic shelters
• Near bodies of water like lakes, rivers, or swimming pools

Outdoor Activities and Lightning Safety

If you’re at a sporting event, hiking, fishing, or even working outside, you need to have a plan. Schools and recreational leagues should establish lightning safety procedures, ensuring everyone has a safe place to go when storms threaten.

Businesses with outdoor employees should also have lightning protocols. Construction workers, landscapers, and utility crews should pause work and seek shelter when storms approach.

By planning ahead and knowing what to do, you can significantly lower your risk of being struck by lightning.
