Key Warning Signs of an Approaching Tornado

Tornadoes are among the most powerful and destructive natural disasters. While tornadoes can be difficult to predict, recognizing early warning signs and understanding storm behaviors can help you stay safe.

Below, we’ll discuss essential concepts that will help you prepare for these extreme weather events, such as:

• The development of tornadoes.
• What are the signs of a tornado forming nearby?
• Other critical indicators to watch out for,
• What can you do to keep yourself and your loved ones safe?
• Why invest in safe rooms for your home?

Understanding Tornado Development

How do you know if a tornado is coming? To answer this question, you must examine the factors contributing to tornado development. Tornadoes often form in severe thunderstorms, particularly those called supercells.

Supercells develop due to unstable weather patterns, such as warm, moist air colliding with colder air. This type of weather condition creates rotating updrafts, which can spawn tornadoes.

Meteorologists use the Enhanced Fujita Scale (EF Scale) to categorize tornadoes based on their intensity and potential damage. This scale’s EF-0 category is rated as the weakest and EF-5 the strongest.

How To Tell if a Tornado Is Coming

While predicting tornadoes remains challenging, there are some tell-tale signs you can watch out for. Let’s take a closer look at the key signs of tornado development:

1. Unusual Sky Colors and Cloud Patterns

In the moments before a tornado forms, the sky can take on eerie shades, like green, dark gray, or yellowish. This unusual color can be caused by light scattering through heavy rain, hail, or dense cloud cover and is one of the important tornado signs to watch out for.

2. Formation of a Wall Cloud

It’s especially important to watch for certain cloud formations, such as wall clouds (large, low-hanging clouds that often rotate) and shelf clouds (a low, horizontal, wedge-shaped cloud that often precedes thunderstorms). Although shelf clouds indicate intense storms, rotating wall clouds are more likely to produce tornadoes. If you notice a wall cloud, pay close attention to any signs of rotation, as this is often an early indicator of tornado development.

3. Strong and Sudden Changes in the Wind

Additional warning signs of a tornado include sudden, intense winds that change direction unpredictably. If you notice abrupt, powerful gusts followed by eerie moments of calm, stay vigilant and seek shelter without delay.

4. Dark, Low-Hanging Clouds with Rotation

Rotating clouds are one of the early tornado signs to pay attention to. Watching for these can be challenging as they often blend in with other storm clouds. However, their swift rotation can signal an impending funnel cloud.

5. Loud, Continuous Roaring Noise

Many tornado survivors report hearing a loud, persistent roar, often compared to a freight train or jet engine, which can be one of the tornado warning signs. Unlike thunder, which comes in bursts, a tornado’s roar is constant and intensifies as it approaches.

6. Intense, Sudden Hail or Heavy Rain

Large hail or intense rainfall can be one of the signs of tornado formation. Hailstones can range from small pellets to baseball-sized chunks, especially in severe thunderstorms. If hail increases in intensity, consider it a warning that the storm is strengthening and could develop into a tornado.

7. Formation of a Funnel Cloud

A funnel cloud is a rotating, funnel-shaped cloud that extends from a storm but hasn’t yet touched the ground, which is one of the key tornado signs. If you see one forming, take cover immediately, as funnel clouds only take a few seconds to turn into full-blown tornadoes.

8. Unusual Cloud Movement and Rotation in the Sky

In addition to funnel clouds, unusual cloud movements or rotations may indicate tornado formation. Persistent cloud rotation signals increase storm intensity even if a funnel doesn’t form or touch the ground. They should not be ignored, as they can contribute to tornado formation.

9. Sudden Darkness or Ominous Greenish Tint in the Atmosphere

Atmospheric changes, such as sudden darkening or a green tint, can be signs of extreme weather. This greenish hue is caused by particles in the air, like moisture and debris, that scatter light in unique ways when storms reach high intensity.

10. Calm Moments in the Middle of a Severe Storm

Remain vigilant if you experience a sudden drop in wind or noise levels during a severe storm. Tornadoes can sometimes occur in these lulls as the storm “reloads” before unleashing full force. Take any calm moments as an opportunity to seek shelter or safety.

Additional Environmental Indicators

In addition to the warning signs above, here are some contributing factors that may signal a coming tornado:

• Debris Cloud Near the Ground: A debris cloud, or a swirling collection of dirt, leaves, and debris near the ground, is a clear indicator of a tornado. The debris cloud suggests high winds even if a funnel cloud isn’t visible. It is one of the potential signs of tornado formation.

• Flash of Lightning with Ominous Shadows in the Clouds: Lightning can illuminate rotating clouds, providing a brief glimpse of funnel clouds or other indicators of tornado activity. Use these moments to look for any signs of swirling or unusual cloud formations.

• Observing Animal Behavior: Animals are sensitive to atmospheric changes and often act erratically before severe weather. Birds may suddenly become silent, and livestock may huddle together. Paying attention to animal behavior can offer another layer of early warning.

The Importance of Safe Rooms

In tornado-prone areas, a safe room can provide a secure place to cover and protect your family or employees. Safe rooms are important investments designed to withstand high winds, extreme pressure changes, and flying debris accompanying tornadoes. They can serve as an essential line of defense during severe weather.
