The weather bureau says a new radar to come online at Mount Isa in north-west Queensland today will help fill a gap in information.
It will complement radars already providing information for western regions at Mornington Island, Longreach and Charleville.
The bureau's Queensland regional director, Rob Webb, says it is the only new radar to be installed in the state under a new federal program.
"It's part of a $48 million project for a number of radars," he said.
"This is the third of four radars around the country and it really is going to allow, every 10 minutes or so, to provide a look at where and how the weather is happening.
"It is going to help our forecasters but importantly we are finding across the state people are using radar to make decisions about their own livelihoods."
Mr Webb says the radar has been installed on the eastern edge of the city.
"This is the only one in Queensland," he said.
"There has been one in New South Wales, one in Hobart and another one is still to be installed in the Northern Territory.
"It is pretty exciting for Queensland, given the size of the state.
"A lot of the radars have been along the coastal strip, so we've now got one near Charleville, Emerald, Longreach and now pushing up to Mount Isa which is a nice gap filler."
