What warning signs indicate a tornado is forming nearby?

April 5, 2026

Quick Answer

Short answer: Watch for dark, greenish clouds, large hail, and loud roar noises, which can signal a tornado is forming nearby.

Warning Signs of a Tornado

To identify potential tornado risks, observe the sky and listen for distinctive sounds. Dark, greenish clouds can indicate a rotating updraft, also known as a mesocyclone. These clouds appear as a large, dark mass with a greenish tint, often accompanied by strong winds and large hail.

Identifying Tornado Formation

As a tornado forms, you may hear a loud roar, similar to the sound of a freight train. This noise is produced by the intense winds within the tornado. The roar can be heard from a distance of up to a mile away, giving you time to respond and seek shelter. Pay attention to changes in wind direction and speed, as these can signal the approach of a tornado.

Preparing for a Tornado

When a tornado warning is issued, quickly seek shelter in a designated safe area, such as a basement or storm cellar. If no underground shelter is available, go to an interior room or hallway on the lowest floor of your building. Stay away from windows and exterior walls, and get under a sturdy table or desk. Cover yourself with a blanket or mattress to protect against debris and flying objects. Crouch in a low, covered position, with your head and neck protected, and wait for the storm to pass.
