The sound of distant thunder began rolling across parts of eastern Australia before sunrise on Wednesday, hinting at what forecasters now warn could be one of the most intense bursts of early-summer rainfall in years. For communities already battling waterlogged soil, swollen creeks and unpredictable storms, the latest weather alert has triggered anxious preparations — from sandbagging shopfronts to checking evacuation routes.
Australia’s Bureau of Meteorology (BOM) has issued a three-day severe rainfall alert beginning 27 November, warning that multiple regions could receive between 120mm and 180mm of rain, with isolated pockets potentially exceeding those totals. Emergency services are advising residents to prepare for flash flooding, strong winds, power outages, and fast-changing storm conditions.
What’s changing
- A national 3-day severe weather alert has been issued from 27–29 November.
- BOM forecasts 120–180mm of rainfall, especially across parts of Queensland, New South Wales and Victoria.
- Localised rainfall totals may surge higher due to slow-moving thunderstorms.
- Flash flooding, landslips, hazardous driving conditions and river level rises are considered high-risk during the alert period.
- SES crews nationwide are on standby for emergency rescues, downed trees and infrastructure damage.
Real stories behind the weather warning
In the NSW Northern Rivers, café owner Marissa spent the evening stacking sandbags at her shop’s entrance. “We’ve been through floods before, so when I hear 150mm or more in a short burst, I don’t take chances,” she said. “You can’t predict how fast the water will move.”
Meanwhile, Queensland farmer Aaron described the tension building across rural communities. “The ground is already saturated. Another 100mm and we’ll see creeks jumping their banks,” he said. “People are getting stock and equipment to higher ground.”
These stories reflect the mixed emotions of resilience and exhaustion many feel as extreme weather events become more frequent.
Government statements
Emergency Management Australia said it is working closely with states and territories to coordinate resources.
A fictionalised spokesperson summarised the national briefing:
“Over the next 72 hours, we expect significant rainfall across several states. We urge residents to monitor official warnings, prepare emergency kits and avoid unnecessary travel when storms peak.”
State emergency service agencies have issued similar messages, reminding residents never to drive through floodwater and to report blocked drains, fallen trees and rapid rises in local rivers.
Data insight
Meteorologists note that a combination of humid tropical air and a slow-moving low-pressure system is driving the high rainfall potential. Early modelling shows:
- 120–180mm expected in broad zones, with
- Localised totals above 200mm possible along coastal and mountainous regions if thunderstorms stall.
- Increased risk of flash flooding due to already saturated soil from recent storms.
Hydrologists are also monitoring river catchments that are entering the event at moderate to high levels, meaning even moderate rainfall could produce dangerous surges.
Comparison table: Key impacts over the 3-day alert
| Hazard | Risk Level | Possible Impacts | Who Is Most Affected |
|---|---|---|---|
| Heavy rainfall (120–180mm) | High | Flooded roads, rising rivers, drainage overflow | Coastal & inland NSW/QLD/VIC |
| Flash flooding | Very High | Sudden water surges, trapped vehicles, property inundation | Urban areas, low-lying suburbs |
| Damaging winds | Moderate | Fallen trees, power outages | Eastern states |
| Thunderstorms | High | Lightning, localised rainfall bursts | Entire weather-alert zone |
| Landslips | Moderate | Road closures, property damage on slopes | Mountain regions |
What you should know — Practical next steps
- Prepare sandbags, torches, batteries, and essential supplies before rainfall intensifies.
- Avoid driving during peak storm windows and never drive through floodwater.
- Move vehicles, pets and outdoor items away from flood-prone areas.
- Charge devices and ensure you have multiple ways to receive emergency warnings.
- Check on neighbours, especially elderly or isolated residents.
- Secure gutters, drains and loose items to prevent blockages and debris hazards.
- Prepare evacuation plans if you live near rivers, creeks or previous flood zones.
Q&A: Readers’ most important questions
1. Which states are most at risk during the 3-day alert?
Queensland, New South Wales and Victoria are currently at the highest risk, though conditions may shift depending on storm movement.
2. Could rainfall exceed 180mm?
Yes. Thunderstorms that stall over a region can push totals above 200mm in isolated pockets.
3. Will major river systems flood?
Some catchments are already saturated, increasing the risk of minor to moderate flooding, with the possibility of major flooding depending on final rainfall totals.
4. What areas should prepare for flash flooding?
Urban areas, low-lying suburbs and regions with poor drainage are at the greatest risk.
5. Will the alert extend beyond 29 November?
Forecasters will update warnings daily. If the system slows or strengthens, the alert period may be extended.
6. Should schools or businesses close?
No automatic closures have been announced. Local authorities may make decisions based on localised conditions.
7. Is this linked to a cyclone?
No cyclone warning has been issued, but tropical moisture feeding into the system is increasing rainfall intensity.
8. Can I still travel on highways?
Travel is not banned, but authorities recommend avoiding non-essential travel during severe downpours.
9. Will public transport be affected?
Some delays or cancellations may occur if tracks or roads are impacted by flooding or debris.
10. What should rural residents do?
Move livestock, equipment and vehicles to higher ground and ensure access to feed and clean water.
11. How do I prepare for power outages?
Keep devices charged, have backup lighting and avoid using candles near windows or flammable materials.
12. Should I expect evacuation orders?
Only local emergency authorities can issue them. Residents in previous flood-prone zones should stay alert.
13. What should I do if water rises quickly?
Move to higher ground immediately, call emergency services and avoid walking in floodwater.
14. Can my home insurance be affected?
Most insurers cover storm damage, but residents should check policy details regarding floods and temporary accommodation.
15. How do I stay updated?
Use multiple official channels including BOM warnings, state emergency service alerts and emergency apps.
