Tornado Warning Signs

Tornadoes are some of nature’s most destructive forces, capable of turning lives upside down in minutes. While they can strike with little warning, knowing the early signs of a tornado can make all the difference in keeping you and your family safe.

And with September recognized as National Preparedness Month, there’s no better time to review these warning signs and make sure you’re ready for whatever nature brings.

Key Tornado Warning Signs

1. Dark, Greenish Sky

Storm clouds often appear unusually dark or green before a tornado forms. This eerie sky color is caused by severe thunderstorms that can produce large hail and tornadic activity.

2. Wall Cloud Formation

A rotating, persistent cloud base—often called a wall cloud—can signal that a tornado may soon develop.

3. Large Hail

While hail itself isn’t proof of a tornado, large hail often accompanies the type of severe thunderstorms that spawn tornadoes.

4. Loud, Continuous Roar

Many survivors describe the sound of a tornado as a freight train barrelling through. If you hear this kind of roar, seek shelter immediately.

5. Sudden Calm After Intense Thunderstorms

Sometimes, after heavy rain or hail, the weather suddenly becomes eerily calm. This shift can indicate that a tornado is forming nearby.

6. Debris Cloud or Funnel Shape

The most obvious sign is a visible funnel cloud or swirling debris near the ground. If you see this, don’t wait—take cover at once.

What to Do If You Notice These Signs

• Take shelter immediately in a basement or interior room without windows.

• Have an emergency kit with flashlights, water, and first aid supplies.

• Listen to weather alerts on a battery-powered radio or phone.

• Avoid windows and large open spaces.
