The Northern Territory town of Katherine is launching a new flood warning system in preparation for the wet season.
The Katherine Counter Disaster Committee's Commander Michael White says the update is needed because the system has changed from a numerical one to a classification of minor, moderate and major flooding.
He says the town's flood warning sirens no longer operate because the committee believes social media and online information are a better way to keep people informed.
The town has been flooded five times in the past 100 years, and Commander White says it could go under again.
"(It's) likely any year that we'll have a big flow of the river," he said.
"One of the feedbacks we got from previous incidents and flood alerts was that there was a bit of confusion within the community about what they meant.
"Using more appropriate language gives people a better understanding of what sort of levels we are expecting in Katherine."
A brochure is being prepared to advise residents of the changes.
