Early Warning Signs of a Tornado

Tornadoes can develop quickly, but nature often gives warning signs before one forms. Recognizing these signals and preparing ahead of time can save lives.

⚠️ Early Warning Signs of a Tornado

1. Dark, Greenish Sky
Severe thunderstorms that produce tornadoes often cause the sky to take on a green or yellow tint, especially in the afternoon or early evening.

2. Large, Dark, Rotating Clouds
Look for a low-hanging rotating cloud, often called a wall cloud. This may appear beneath a larger thunderstorm.

3. Loud Roaring Sound
Many survivors describe the sound of an approaching tornado as similar to a freight train or jet engine.

4. Large Hail or Sudden Calm
Tornado-producing storms frequently drop large hail before a tornado forms. Sometimes winds suddenly go eerily calm just beforehand.

5. Debris Falling From the Sky
If you see branches, leaves, or debris being lifted or falling, a tornado may already be forming nearby.

6. Funnel Cloud
A visible spinning funnel extending downward from the cloud base is a clear sign a tornado could touch the ground at any moment.

🛠️ How to Prepare Before a Tornado

1. Identify a Safe Shelter

  • Basement or storm cellar (best option)
  • Interior room on the lowest floor
  • Away from windows (bathroom, closet, hallway)

2. Build a Tornado Emergency Kit
Include:

  • Flashlight & batteries
  • Weather radio or phone alerts
  • Bottled water & snacks
  • First-aid kit
  • Whistle to signal rescuers
  • Phone chargers / power bank
  • Important documents in waterproof bag

3. Secure Your Home

  • Trim trees and remove loose outdoor objects
  • Reinforce garage doors if possible
  • Know how to shut off gas, water, and electricity

4. Have a Family Plan
Everyone should know:

  • Where the safe room is
  • How to contact each other if separated
  • Where to meet after the storm

🚨 What to Do When a Tornado Warning is Issued

  • Go immediately to your shelter area
  • Protect your head with a helmet, mattress, or heavy blankets
  • Stay away from windows and doors
  • If outside with no shelter, lie flat in a low ditch and cover your head (avoid bridges/overpasses)

✅ Important Tip:
Many injuries occur from flying debris, not the wind itself. Head protection dramatically reduces risk.
