A bomb cyclone is forecast to intensify rapidly off the south-east Australian coast from late Wednesday, bringing damaging winds and heavy rain to coastal Victoria, New South Wales and Bass Strait. The low-pressure system is expected to deepen by at least 24 hPa in 24 hours, meeting the meteorological definition of bombogenesis.
What is a bomb cyclone and how does it affect southern Australia?
Bomb cyclones are extratropical lows that undergo explosive deepening, often along the Southern Ocean frontal zone. For Victoria and NSW, the approaching system will generate gale‑force winds, dangerous surf and prolonged rainfall. The Bureau of Meteorology’s bom cyclone tracking map shows the low centred near 48°S, 152°E, moving east-south-east. Communities from Eden to Lakes Entrance should prepare for coastal erosion and localised flooding.
Where can I track the system live?
For real‑time updates, the bom cyclone tracking map live feed on the BOM website provides satellite imagery, pressure tendencies and wind fields. The bom cyclone tracking map australia satellite tool overlays infrared and visible bands to highlight convective bands. A bom cyclone 7 day forecast indicates the low will weaken over the Tasman Sea by Saturday.
Is a bomb cyclone the same as a tropical cyclone?
No. Bomb cyclones are mid‑latitude lows that deepen explosively, while tropical cyclones derive energy from warm ocean water. A cyclone warning today for a bomb cyclone focuses on extratropical hazards: wind, swell and frontal rain.
When will conditions ease?
Winds are expected to peak Thursday night and ease by Friday afternoon as the low moves beyond the Bight. Coastal residents should monitor the bom cyclone tracking map for changes.
Where is the best source for official warnings?
The Bureau of Meteorology issues Severe Weather Warnings for bomb cyclones. Check our Severe Weather Warning page and the Weather Radar for local rainfall intensity.
