The major rainfall event that has drenched coastal Queensland over the last few days, has now spread inland bringing hopes for good falls for winter croppers in southern Queensland and northern NSW.
The low pressure system to the northeast of Mackay, which was expected to thrash Brisbane with winds reaching speeds of 110kmh, has rapidly weakened.
Bureau of Meteorology forecaster Andrea Peace said moderate rainfall is expected across the south east tonight, "just not to the severity initially predicted".
"The interaction between (the) lower system and the upper system now moving from the south west made it very difficult to predict the weather," Ms Peace said.
While rain eased in Brisbane yesterday, Bureau of Meteorology senior forecaster Jonty Hall said more is expected today as the new upper trough system moved through central Australia.
"It should produce decent falls over inland south east Queensland as well, including the dam catchments," Mr Hall said.
Dam levels in south east Queensland are expected to pass 40pc for the first time in three years as heavy rain continued to fall across the catchments today.
A weather system of the same type that stranded the Pasha Bulka in NSW last year will bring as much as 200mm across the south-east coastal region over the next couple of days, forecasters said.
Bureau of Meteorology forecaster Stephen Fletcher said the weather system bringing this rain was typical for this time of year, but it was not common for them to reach south east Queensland.
The east coast low is currently off the Central Queensland coast.
The Bureau says the cloud over southern and central parts will bring rain to the southern interior, south of about Longreach and about the southeast coast south of about Gladstone today.
Rain areas will gradually contract south of Tambo to Gympie tomorrow, with moderate falls likely about the south-east coastal districts.
A little morning drizzle will develop Monday morning over southern and central areas with some isolated afternoon showers as far north as Winton to Clermont.
The upper level low over western Queensland will move southeast towards the western Darling Downs on Monday and then eventually out of the State and into northeast NSW on Tuesday.
The rain associated with the upper trough will also contract to the southeast and then out of the State during Tuesday.
For northern NSW's the Bureau says a trough off the NSW north coast is expected to deepen with a low centre forming off the north coast by Tuesday.
This low should drift to central parts of the coast during the week.
In combination with an upper low over the north-west of the State, which is moving east, areas of rain will spread across much of the north and east during the week, with some moderate to heavy falls.
