Severe thunderstorms producing heavy rain, large hail and lightning are impacting parts of Queensland and NSW on Thursday. Winter is a quiet time for thunderstorm activity in eastern Australia because there is less atmospheric instability and surface heating for the storms to develop compared to spring and summer. However, there are rare cases where all […]
Abnormally warm oceans surrounding Australia and a developing negative Indian Ocean Dipole will increase the likelihood of abnormally wet weather across large parts of the country this spring, along with an increased risk of flooding and severe thunderstorms disrupting businesses and industries. Spring in Australia runs for three months from the start of September to […]
Sydney’s soggiest August weekend in nearly three decades adds onto an already well above average month of rain as moist onshore winds stream into eastern NSW, with saturated grounds leaving NSW businesses and industries in a vulnerable position. Video: Radar imagery showing rainfall moving across the metropolitan region on Sunday, August 10, 2025. A moist […]
A powerful low pressure system off Australia’s East Coast in early August generated long period wave energy directed towards the coastline – some of which threaded under the Great Barrier Reef into Queensland’s Central Coast. Easterly gales wrapping around the system between Sunday and Tuesday were around 1,000 nautical miles away from Hay Point, a […]
A strong positive phase of the Southern Annular Mode (SAM) is about to occur in the Southern Hemisphere, increasing the likelihood of wet weather in eastern Australia and reducing snow prospects in southern Australia over the coming week. What is the SAM? The SAM is an index that measures the north-south displacement of a belt […]
The Indian Ocean Dipole (IOD) index has dropped below -0.4°C – the critical threshold for a negative IOD event if sustained. Could Australia see its first negative IOD event since 2022? What is the Indian Ocean Dipole (IOD)? The IOD is a measure of the difference in Sea Surface Temperatures (SST) across the equatorial Indian […]
A cold Southern Ocean air mass will spread across Australia this week, causing a run of wintry days and nights for much of the country before possibly culminating in heavy rain along the east coast. The image below shows a tongue of cold air extending from the Southern Ocean towards southwestern Australia on Monday. This […]
Significant rain has fallen across the southwest of WA, with Perth recording 41mm in the 24 hours to 9am Monday, making it the city’s wettest day in just over a year. This latest soaking means that Perth has now exceeded its average monthly rainfall, with 174.2mm in the gauge for July 2025 to date, compared […]
A strong cold front crossing WA is drawing a deep feed of tropical moisture and rainfall across nearly the whole state, impacting mining hubs. Well before dawn on Thursday, a quick but intense burst of rain crossed over Port Hedland, delivering 12mm in the 30 minutes to just after 3am. Across the whole night, the […]
Severe thunderstorms impacted southwest WA and the Perth region on Sunday, December 14, 2025, triggering Dangerous Thunderstorm Alerts (DTA) by DTN for industries and businesses in the region. DTN operates Dangerous Thunderstorm Alerts (DTA) which alert businesses and industries to thunderstorms based on intensity and movement. These alerts provide advanced notice of thunderstorms moving into […]
Port and maritime operations across Australia’s East Coast could be disrupted by increased tropical cyclone activity in the Coral Sea and southwest Pacific Ocean over the next two weeks. Meteorologists reference a large selection of Numerical Weather Prediction (NWP) models to forecast weather. A number of these NWP models are forecasting the development of tropical […]
Hot, dry and windy weather causing elevated fire danger and severe heatwave conditions are sweeping across southeastern Australia over the next three days, driving high energy demand and disruption to operations. Clear skies associated a large and slow-moving high pressure system have allowed hot air to build up over parts of northern, western and central […]
The Australian and New Zealand Council for fire and emergency services (AFAC) identified western and southern WA, Victoria and inland NSW as key regions that are at risk of heightened bushfire risk this summer. Parts of Australia have experienced severe soil moisture and rainfall deficiencies over the past months and years, while high fuel loads […]
