Heavy rainfall and squally thunderstorms will intensify over southern India with the arrival of the southwest Indian monsoon this week. The Indian Meteorological Department (IMD) is responsible for tracking the advance of the monsoon over the Indian sub-continent. The latest map issued by the IMD shows the northern limit of the southwest monsoon just to […]
Rain will continue to inundate already flooded eastern NSW for another two to three days as a stubborn low pressure trough lingers near the coast, impacting transport networks and businesses. A deep layer of moisture-laden winds feeding a slow-moving low pressure trough have been causing persistent and heavy rain over parts of eastern NSW in […]
Intense rain, large waves and powerful winds are lashing eastern NSW as a deep low pressure trough lingers near the coast, with a dynamic week ahead. The satellite imagery below shows the stream of moisture moving over eastern NSW on Monday – with wild and woolly conditions whipped up out at sea. Image: water vapour […]
Tropical lows, monsoonal winds, heavy rainfall and earthquakes are affecting areas around Australia, bringing weather much more typical to the wet season. Tropical Lows 33U and 34U Tropical lows and cyclones can form at any time of year but become much less frequent over the Australian region during the Southern Hemisphere winter. This is due […]
Northern Australia’s 2024-25 wet season featured the busiest cyclone season in 19 years, latest monsoon onset on record and intense thunderstorm outbreaks. The northern Australia (north of 26°S) average wet season rainfall in 2024-25 was 21% above the 1961-1990 average. As seen in the rainfall deciles map below, this above average rainfall was driven by […]
The Pacific and Indian Ocean climate drivers remain in a neutral phase, with weather around Australia continuing to be dominated by more local effects. Pacific Ocean climate driver The El Niño Southern Oscillation (ENSO) has returned to a truer neutral phase, after trending towards a La Niña-like phase during summer. Sea Surface Temperatures (SST) across […]
An outbreak of heavy rain and severe thunderstorms will impact Victoria and NSW over the coming long weekend. As seen in the synoptic image below, this outbreak of storms and wet weather will be caused by a broad low pressure trough and cold front. Image: Synoptic image for Friday, 25 April. As the weekend goes […]
Tropical Cyclone Errol, which formed on Tuesday night, is quickly gaining strength to the north of WA and could turn towards the Kimberley coast later this week. At 8am AWST on Wednesday, Errol was a category two tropical cyclone located roughly 515 km to the north northwest of Broome. The system is moving west and […]
A tropical cyclone is likely to form off the north coast of WA in a matter of days, with signs that it could become a severe tropical cyclone next week. A tropical low is currently developing over the Timor Sea to the north of Darwin. The circulation centre of this developing low can be clearly […]
El Niño–favourable conditions are gathering pace across the tropical Pacific, with key ocean indicators approaching threshold levels and early atmospheric responses emerging. While uncertainty remains around final El Niño strength, historical analogues show that even weak events can generate widespread impacts, including reduced rainfall, warmer daytime temperatures, increased frost risk, elevated fire danger, reduced tropical cyclone activity, and more. Industries including […]
Australia has just experienced a highly impactful tropical cyclone season, with more than 60% of systems reaching severe intensity, causing widespread disruption and damage to communities and multiple industries across northern Australia. The 2025–26 Australian tropical cyclone season officially ran from 1 November 2025 to 30 April 2026. During this six-month period, Australia saw 11 tropical cyclones, with nine […]
There are signs that a very strong, or ‘super’ El Niño could develop in the tropical Pacific Ocean later this year. So, what does this mean for Australia’s weather during the second half of 2026? El Niño on the horizon The tropical Pacific Ocean is currently in a neutral state, meaning neither El Niño nor […]
Intense heat from bushfires during elevated fire danger days can trigger fire-induced pyrocumulonimbus thunderstorms that ignite additional fires. In early January 2026, an extreme heatwave sweeping over southeastern Australia brought catastrophic fire danger to Victoria. Intensely hot bush and grass fires spread erratically and quickly in hot, dry and gusty winds, with pyrocumulonimbus generating lightning, […]
