Australians along the eastern seaboard are bracing for a "peak day of rainfall" today with totals of 25 to 100mm anticipated for NSW, Queensland, the ACT and eastern Victoria.
Bureau of Meteorology meteorologist Jackson Browne said a low pressures system over eastern South Australia was moving east towards the east coast in a severe weather update.
"Accumulated rainfall shows our cloud band shifting over the eastern two thirds of Australia with Thursday being the peak day of rainfall. Widespread falls of 25 to 100mm with higher amounts and thunderstorms are likely," Mr Browne said.
"The track of this low pressure system will dictate exactly where the strongest rainfall will be. Widespread rainfall should extend along the east coast of Australia on Friday with conditions beginning to fine up, at least for most of NSW and Victoria, by Saturday."
Severe weather warning for heavy rainfall have been issued across multiple states and "further warnings are likely".
There are also a number of flood warnings across NSW, Queensland, Victoria, South Australia and the ACT.
"Flood warnings are current over multiple river catchments with some exceeding the major flood level in NSW and Queensland. Dams are full and many catchments are either flooded or saturated so any further rain or thunderstorm activity this weekend will need to renewed river level rises across many rivers and creeks," Mr Browne said.

"Flood watches have also been issued in anticipation of the upcoming rainfall. Residents living on and near flooded rivers and creeks, especially in parts of NSW, Queensland and eastern Victoria, need to stay alert to the latest forecasts and warnings as many rivers are likely to experience flooding in the coming days."
