Parts of Central and Western Queensland have copped a drenching overnight with more storms expected to develop throughout today.
The Bureau of Meteorology recorded 146 millimetres at Emerald, 131mm at Springsure and 149mm at Heathwood since 9am Tuesday.
Further west, Longreach recorded 34mm with more storms expected today.
Bureau of Meteorology senior meteorologist Steven Hadley said October rainfall records in the Central Highlands had been broken.
"Some sites in central Queensland have recorded higher amounts in the last 24 hours to 9am than they have in some of their records," Mr Hadley said.
"So for instance, in Springsure, Rewan and Emerald, they've all seen over 100mm. That's more than they've seen in a day in October in the record books."
More storms are expected to develop further west today and through the Central Highlands and Coalfields.
"There's potential for further heavy falls in those areas that received all the heavy rainfall today, so potentially we could see some severe thunderstorm activity through northern, central, and southern parts of inland Queensland," Mr Hadley said.
"There's a risk of some flash flooding in those areas ... as well as some really strong wind gusts and also the potential for large hail across the south of the state."
David Keene's cattle property at Springsure copped a drenching in a short period, recording 122mm.
"It started at six [last night] and we were watching and thinking, 'Gee this is going up really quick'" he said.
He welcomes the falls and says the cattle are safe, staying high and dry.
But for others, the rain comes at an unfortunate time.
Larry Daniels grows mixed crops between Emerald and Clermont and was in the middle of his wheat and chickpea harvest this week.
"If it continues to rain, it'll be downgrading and lodging and all sorts of problems," he said.
"Only about 100 acres of it was ripe to harvest ...we needed another week, [and] we want sunshine now.
"But we do have spring sorghum in, and the rain was just what it needed."
Luke Bradley, a grower in the Springsure area, has wheat, barley, and chickpeas in the ground at the moment.
"We've only had 42 millimetres at Springsure ... we've been really fortunate with those sort of lower figures" Mr Bradley said.
"It's quite a disruption [for harvest] ... and a lot of growers are really in need of a good harvest in central Queensland.
"We haven't had a decent season for a couple of years and this is beautiful crop that's in the ground ... So, it's very frustrating."
Brad Foster, regional manager for GrainCorp, said the harvest period had been building, with about 170,000 tonnes received into the business' network so far this season.
"We took 20,000 tonnes yesterday, mainly in central Queensland, so we were ramping right up, [but] the rain's brought it to a halt very quickly," he said.
Multiple road closures
Glen Bell, disaster coordinator for the Central Highlands Regional Council, said as the rain fell in a short period of time some roads have been closed.
While there have been no reports of homes flooded or rescues required, motorists need to take care.
"A lot of these the main roads will be temporarily affected or highly dependent on more rainfall," Mr Bell said.
"The [Gregory] highway will be fairly quick; it will move on rather quickly.
"But some of the local roads in the western areas though, they'll be affected for an extended period of time."
Mr Bell said locals should be prepared for further rainfall and possible flash flooding this week.
"Of concern to us is the Rubyvale and Sapphire areas, they're well and truly saturated now, so it won't take much for those creeks and rivers to rise, and people need to be aware of their surroundings," he said
