What is a tornado warning?
The NWS issues a tornado warning when a tornado has been seen or weather radar indicates one in the warned area. Warnings are drawn as polygons around the storm's path and usually last 30 to 60 minutes. A warning means the hazard is happening, about to happen, or very likely: act now to protect people and property. The national record · Every warning type in Maine.
