DOWNPOURS of 50-100mm are expected to fall over the South Burnett before the week ends.
Spokesman for the Bureau of Meteorology Jess Carey said there would be one to two days of rainfall moving over the area.
"Sometime Friday the worst of the rain fall will clear for the South Burnett areas," he said.
Mr Carey said there was a flood watch for the South Burnett and Mary catchments and that residents should expect localised flooding.
"There is no flood warning at the moment, but people just need to be aware," he said.
"It's been a relatively dry wet season, so the soil will act as a buffer, soaking up that moisture.
"It hopefully won't fall through intensely."
Paul Pratt from Murgon Cattle Sales said the Murgon Weaner Sales on Friday would be affected as a result of the rain.
"We've lost about 100 cattle so far," he said.
"The trucks can't get in."
Despite the dreary conditions Mr Pratt said the sale would still go through.
"900 cattle will be there," he said.
Mr Carey said people in the South Burnett were well aware of the risk of flooding.
"A lot of people in the area have experienced flooding, so hopefully people have their own emergency plans," he said.
Mr Carey said the worst of the storm would be to the south of Fraser Island and the coast, where they would experience two or three days of rainfall.
