Many regions of Australia are being advised to prepare for severe rain as summer draws near. A significant three-day heavy rainfall signal has been issued for eastern and southeast Australia as of November 27, 2025. Rainfall in several areas might reach 180 mm over three days, according to forecasters. That’s a lot of water in a short period of time, and it carries significant concerns.
Since the ground is already saturated from earlier rains in many places, this caution is crucial. This implies that the fresh rain may run off rapidly and flood streets, rivers, and neighborhoods rather than soaking in. This might cause danger, disturbance, and anxiety for residents of low-lying or flood-prone locations.
Communities are being advised to pay alert, get ready early, and stay out of dangerous situations as a result. A summary of what’s going on, who is at risk, what to anticipate, and what individuals can do right now to keep safe is provided below.

A Deep Weather System Pulls in Heavy Moisture
According to meteorologists, warm tropical moisture and a deep low-pressure system are what are causing this phenomenon. Storms can build rapidly when these elements come together with a cold front moving from the south.
Thick cloud cover, unexpected downpours, and protracted spells of intense rain throughout many states are the outcome.
According to experts, the system is “slow-moving,” which means that rain might remain over the same spots for hours, raising the possibility of flash floods even in locations that typically drain rapidly.
Which States Will Be Hit the Hardest?
| State / Territory | Expected Rainfall (Approx.) | Main Impact Zones | Major Risks |
|---|---|---|---|
| New South Wales (NSW) | 120mm – 180mm | Northern Rivers, Mid North Coast, Hunter, Central West | Flash floods, river rise, road closures |
| Queensland (QLD) | 90mm – 150mm | Brisbane, Gold Coast, Sunshine Coast, Darling Downs | Creek flooding, storm damage, dangerous winds |
| Victoria (VIC) | 80mm – 120mm | North-East Victoria, Gippsland, Great Dividing Range | Localised flooding, landslip risks, power outages |
| South Australia (SA) | 60mm – 90mm | Adelaide Hills, Mid North, Riverland | Sudden heavy rain, minor flooding, travel delays |
| Northern Territory (NT) | 50mm – 120mm | Darwin, Palmerston, Katherine region | Tropical storms, fast downpours, strong winds |
| Western Australia (WA) | 20mm – 60mm | Kimberley, Pilbara (isolated storms) | Local storms, brief heavy bursts |
| Tasmania (TAS) | 30mm – 70mm | North and East Coast | Wet roads, windy conditions |
Why This Weather System Matters
The severity and duration of this occurrence are worrying, even though significant rainfall is common in late April. The earth will find it difficult to absorb the water quickly in many areas due to the storms’ three-day prediction.
This raises the possibility of:
- Roads that are flooded
- Quick river rise
- Drains that overflow
- Flash flooding that is localized
- Power disruptions
- Transportation service delays
Cities and Towns on Watch
Sydney, Brisbane, Melbourne, Adelaide, and other major cities will all be affected to some extent. The anticipated amount may overflow sewers and low-lying streets, even though inner-city regions are typically better suited to withstand high rainfall.
Stormwater can accumulate rapidly, therefore suburbs near rivers, streams, or coastal areas should be particularly vigilant.
Local communities like:
- Lismore
- Dubbo
- Tamworth
- Wagga Wagga
- Toowoomba
- Bendigo
- Mildura
Transport and Travel Disruptions Likely
It is anticipated that wet weather would impact:
- Operations at airports
- Important roads
- Lines of trains
- Roads in rural areas
Because even shallow water can be hazardous and conceal damage beneath the surface, drivers are advised to stay away from flooded roadways.
Severe thunderstorms or flooded rails may cause disruptions to public transportation.
Emergency Services Issue Strong Warnings
People are being urged by state emergency services in all impacted areas to remain vigilant, stay informed about warnings, and prepare their property as needed.
Important reminders consist of:
- Gutter cleaning prior to a significant downpour
- Safeguarding outdoor objects
- Steer clear of needless travel during storms
- Avoiding flooding
- Keeping an eye on local warnings
What to Expect After the Rain Event
Australia’s southern regions will see cooler air when the system passes, while the country’s northern regions will once again have warm, humid weather.
Authorities anticipate:
- Rivers will continue to rise when the rain stops.
- Certain places will require cleaning efforts.
- Potential hold-ups in the reopening of specific roadways
- Storm risk will persist if tropical moisture persists.
It might take a few days for communities affected by severe rainfall to completely dry out.
