The likelihood of La Niña occurring in 2025 has increased due to a change in the way the Bureau of Meteorology calculates sea surface temperature anomalies in the tropical Pacific Ocean. What is La Niña? La Niña refers to a distinct pattern of sea surface temperatures across the tropical Pacific Ocean. When La Niña is […]

Stratospheric warming high above Antarctica could cause the Southern Hemisphere’s polar vortex to weaken at an unusually fast pace over the coming weeks. This weakened polar vortex has the potential to affect weather patterns across Australia and other parts of the Southern Hemisphere. What is the polar vortex? The polar vortex is a large circulating […]

Severe thunderstorms, tornadoes and flooding rainfall have disrupted transport, rail, aviation and many other industries across NSW as a low pressure system tracked over the state. Severe thunderstorms and tornadoes in western NSW A tornado was observed near the town of Young on the South West Slopes of New South Wales around 3:30pm on Wednesday […]

Intense and disruptive thunderstorms, rain, strong winds and large surf will develop along eastern NSW later today, bringing localised areas of flooding and hazardous driving conditions. A cut-off low currently tracking over western NSW, is bringing heavy rain and thunderstorms to the region. This burst of early spring storms already marks the wettest September day […]

Intense and severe thunderstorms across remote and hard to reach mining areas of Australia – typically outside of traditional radar coverage, were detected by DTN’s vast network of remote sensing products. Numerous outback locations in three states and the Northern Territory saw thunderstorms with heavy rainfall from Monday afternoon through to Tuesday morning. Notable 24-hour […]

A negative Indian Ocean Dipole event is a near certainty to develop in 2025 as both the oceans and atmosphere show strong signs of coupling. What is the Indian Ocean Dipole? The Indian Ocean Dipole (IOD) is a climate driver that involves the movement and location of warmer and colder waters along the equator in […]

The latest seasonal bushfire outlook from Australian Fire and Emergency Service Authorities Council (AFAC) warns of elevated fire risk for northern Western Australia, eastern South Australia and much of western Victoria this spring. In WA, a large portion of the Kimberley and inland Pilbara are highlighted as areas at an increased risk of fires this […]

Relentless rainfall has soaked already sodden areas of eastern NSW this week, leading to flooding, road and rail disruptions, and Sydney’s wettest August day in nearly two decades. A deep stream of moist easterly winds has cause rain to soak parts of NSW and southeast Queensland every day between Monday and Friday this week. Most […]

One of Australia’s key climate drivers is gaining strength over the Indian Ocean, firming up the odds of a wet spring for large parts of the country. The Indian Ocean Dipole (IOD) refers to an index that measures the difference in sea surface temperature anomalies across the tropical Indian Ocean. It’s an index watched closely […]
