The founder of an online weather service is calling for additional radars to be installed around the state to fix what he calls 'black spots' in weather surveying.
Perth Weather Live founder Steve Brooks is lobbying the State Government to install doppler radars in the Margaret River region where cold fronts are common and in the cyclone-prone Pilbara.
"It does give you a bit of a better range of accuracy that's for sure," he said.
Mr Brooks says despite the expense, doppler radars are common in other states and are useful in detecting changes in wind direction and intensity.
The Bureau of Meteorology's, Mike Bergin, says the radars are more of a want than a need.
"I don't think it makes a great deal of difference to the quality of the warnings that we're able to issue," he said.
Mr Bergin says weather radar coverage could be improved in the inner Pilbara and the Wheatbelt.
