Ex-tropical cyclone Fletcher is unlikely to reform over the Northern Territory, but forecasters are warning heavy rains could cause more flooding.
The Bureau of Meteorology says the tropical storm is no longer expected to merge with another low sitting south of Katherine.
Instead Fletcher will further weaken while the other trough will track southwest towards Western Australia.
However, heavy rainfall of up to 100 millimetres is expected to continue causing rivers across the Top End to flood and causing road closures.
The Darwin and Daly rivers, Roper and McArthur rivers, north and eastern Victoria River and northern Barkley districts will be affected.
