The southern hemisphere’s polar vortex is weakening in response to a rare episode of stratospheric warming above Antarctica, a phenomenon that could affect weather patterns across Australia in the coming weeks. What is the polar vortex? The term polar vortex refers to a large rotating column of cold air surrounded by powerful winds, which develops […]
Hot and windy weather are bringing extreme fire danger near Darwin on Wednesday, just days after the city saw its first rain in four months. Prior to last weekend, Darwin had not seen any rain since May. This 115 day dry spell came to an end when rain started pouring into the gauge on Sunday […]
For four months in a row, Perth has exceeded its average monthly rainfall – the first time this has happened in the traditionally wet winter and spring period since 2007. Perth reached its September average of 79.3mm during light showers on Tuesday and Wednesday. Another 13.2mm of rain then fell in the 24 hours to […]
Aviation, mining and shipping industries in the Solomon Islands and other South Pacific nations are often unable to use traditional radar to warn of incoming storms that disrupt operations and put workers in harm’s way. DTN APAC offers a suite of remote sensing weather solutions that give businesses and industries in remote areas around the […]
A negative Indian Ocean Dipole (IOD) event is now underway, increasing the likelihood of above average rain over large parts of Australia in the coming months. What is the Indian Ocean Dipole (IOD)? The IOD is an index used to monitor sea surface temperatures across the tropical Indian Ocean. It’s an important index for the […]
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 […]
Australia’s tropical cyclone season is officially underway, but we may not see much activity for few months yet. The season runs from November to April, and for mining operators and businesses across northern Australia, 2026-27 is shaping up to be a season where the headline numbers and the real risk may not line up. On […]
A positive Indian Ocean Dipole is underway, but this one is unlikely to deliver the textbook dry spring and summer that businesses have come to expect from the pattern. The Bureau of Meteorology officially declared a positive IOD on Tuesday, October 27, which typically like El Niño can cause drier and warmer conditions over parts of […]
Waters off Indonesia have cooled in recent weeks, an indication that a positive Indian Ocean Dipole (IOD) event could be developing. It’s an important climate driver for Australia, and it could shape rainfall and temperatures heading into summer, with flow-on effects for farmers, energy and other industries. What is the Indian Ocean Dipole? The IOD […]
Leonora, WA, had its wettest September day on record earlier this month. Three weeks later, more than 1.3 million lightning pulses were detected within 800 km of the town in 48 hours. Why is a stalled trough delivering storms to mining country, and what it could mean for operations? The DTN Total Lightning Network detected […]
