The weather bureau says a radar installation being built in Arnhem Land will fill an important gap in the monitoring of cyclones in northern Australia.
The radar facility is under construction at Warruwi on Goulburn Island, about 300 kilometres north-east of Darwin, and is expected to be operating by January.
Bureau regional director Andrew Tupper says it will improve cyclone coverage and predictions.
"We have known for some time there is a little bit of a gap in our radar cyclone monirtoring," he said.
"That was really evident when Cyclone Monica hit the coast west of Maningrida in 2006.
"We were fortunate in obtaining federal funding to build a radar at Warruwi for the purpose of filling that gap and giving us some really nice radar coverage for the north.
"As far as the Top End coast is concerned, the coverage is going to be a heap better."
Mr Tupper says there are still some weak points in the radar system around the Gulf of Carpentaria.
