In what is going be a September to remember for record rainfall and flooding Australia's four flood-affected states will receive another burst of rain in the next two days.
A string of rain-bearing systems in recent weeks has left rivers inundated across western and southern Queensland, western New South Wales, western and northern Victoria and eastern Tasmania. All states have warnings in place today, with major flooding continuing along the Lachlan River in New South Wales and the Avoca and Wimmera Rivers in Victoria.
A low pressure system and associated cold front will cross South Australia tomorrow and interact with a trough over central Australia with rich moisture streaming down from the Top end (which has recived record September rainfall the past 24 hours), producing widespread rain and thunderstorms. By Tuesday night, rain will spread into western, central and southern inland Queensland, and western parts of New South Wales and Victoria. The system will then push showers and rain areas over Tasmania, remaining parts of Victoria, New South Wales and the rest of central and southern Queensland on Wednesday.
State by state What SYSTEM FOUR WILL PROVIDE
NORTHERN TERRITORY
Southern parts of the state, eastern Alice Springs region: 50-100mm with numerous thunderstorms. Top End should see another 20-50mm including the Darwin region with isolated heavier falls with thunderstorm activity.
SOUTH AUSTRALIA
The best of the falls will be on and east of the Eyre Peninsula & Lower Eyre Peninsula, Flinders & Mid North will received 10-20mm, Riverland, Murrylands and Upper and Lower south east 10-20mm this includes Adelaide. Northern parts of the North east Pastoral 30-60mm. Any thunderstorms that develop may produce locally heavier falls in some regions.
VICTORIA
Most the state should see 15 to 40mm with this system, parts of the ranges may received 50mm including flooded ravaged regions of the north west catchments with isolated falls to 60mm about elevated regions of the north east. Melbourne is likely to receive 15 to 30mm with this system. Thunderstorms may produce heavier falls. This could well make the flooding situation worse across parts of the state.
TASMANIA
The best of the falls are likely about the north and east but this heavily depends on the low but at this stage these regions are likely to see rain again general falls of 10-25mm about the north and east however if the low moves further south falls will be heavier consequently if the low stays further north falls will be lighter about the north and east.
QUEENSLAND
Once again the best of the falls will be west of the ranges and south of Richmond to Rockhampton with western and southern inland expected to see the heaviest falls 25 to 60mm in these regions with isolated falls nearing 70-80mm especially with any thunderstorm developlement. East of the ranges falls will be lighter including the Brisbane region with 5 to 20mm expected for the Queensland capital.
Parts of the Maranoa & Warrego district, Channel Country, Central west and the Darling downs will see the heaviest falls with thsis system already falling on extremely wet terrain and flooded regions. Any thunderstorms that develop will produce locally heavier falls.
NEW SOUTH WALES
Most of the state will receive 10 to 40mm with this system with possible higher falls about the ranges and with thunderstorms. The southern highlands may see 50mm+. No doubt this will make flooding conditions worse.
The ACT should see 10-30mm while Sydney should received 10-15mm with local falls around 20mm or so especially if thunderstorms develop.
More to come...
