The prolonged spell of rain is predicted to bring widespread totals in the range of 50 to 100mm from the Kimberley through to the southern parts of the Northern Territory and on to tropical Queensland.
If it eventuates, it will be the most widespread winter falls in at least 16 years and well above the average rainfall for the entire season which for most of tropical Australia sits at less than 25mm.
Large parts of Australia are coming to the end of a very wet June, defying the Bureau of Meteorology’s earlier grim long-range outlook for a parched month.
Off the back of significant cold fronts and an unusual stream of tropical moisture currently feeding across the country, parts of southern WA, South Australia, Victoria and New South Wales have received two to three times their monthly average rainfall for June.
Some parts of northern Australia have received more than quadruple their average rainfall for the month, although this is easier to achieve given very little rain falls at this time of year.
Although June figures won’t officially be in until tomorrow, it also looks as though several monthly rainfall records were broken as well.

Parts of outback Queensland have been inundated by heavy rainfall over the weekend, as a rainband moves across the state.
Mount Isa has eclipsed its wettest July day on record, with more than 110 millimetres of rain falling on the outback mining city since 9am yesterday.
The new record has almost doubled its 1978 record of 62 millimetres in 24 hours.
Cold and rainy June weather breaks records across southwestern Australia
Heavy rainfall has broken records across southern Western Australia while several south-west towns shivered through their coldest June days on record.
Eyre’s weather station on the Nullarbor, about 840 kilometres east of Albany, recorded the coldest temperature in WA on June 26 when the temperature reached just -4.7C.
