Waterspout
Several WHNT News 19 viewers sent in pictures of a waterspout near Decatur on the Tennessee River Friday evening.

The picture above was submitted through our Live Alert 19 app by user "baker630456."

Waterspouts can sometimes cause damage if they move onshore, but the National Weather Service in Huntsville said it had not heard of any damage reports from this storm system.

Waterspouts fall into two categories: fair weather waterspouts and tornadic waterspouts.

Tornadic waterspouts are tornadoes that form over water, or move from land to water. They have the same characteristics as a land tornado. They are associated with severe thunderstorms, and are often accompanied by high winds and seas, large hail, and frequent dangerous lightning.
