Dark Greenish Sky

The green comes from the hailstones that are being reflected by the sunlight. It is a typical occurrence with tornadoes and storms. Other instances say that the sky turned into dark even close to gray up to black in the color scheme.

It can also happen even if it is in the middle of the day. Regardless of how dark it can get, it is vital to seek cover.

High-Frequencies of In-Cloud Lighting

It is a very tricky sign to spot-on as the lightning usually stays within clouds. It never touches the ground, and many people are unaware of it. The only thing that remains visible is the large accumulation of wall of clouds that turns into a funnel shape.

Spotting lightning can become simpler when you have a dangerous thunderstorm alert. DTA will give you a detailed alert of when the lightning is forming and in full force.

Calm After A Thunderstorm

Tornadoes usually happen after a thunderstorm. It is a common occurrence when a storm occurs, and the sky appears to be calm and clear. Don’t be fooled by this. It is an indication that a tornado is about to take its form.

Funnel-Shaped Cloud

It is one of the most obvious signs that a tornado is about to come. You will see a visible funnel-shaped cloud that is rotating and slowly making its way down the earth. It is visible even if you are miles away.

Continuous Rumble

As the tornado is coming down in contact, you will be able to hear a loud and persistent rumble. It sounds like a train moving past your building. If you hear this, you need to take immediate action.


Overall, these are five of the basic warnings about tornadoes. It is essential to have a plan and prepare for the worst during this kind of calamity. The safest possible place in your house will be your basement.

But if you don’t have it and you still have time to evacuate, find the nearest shelter for you to stay. Be alert and always take cover every time to secure your survival.
