A negative phase of the Southern Annular Mode (SAM) has developed in the Southern Hemisphere and it’s going to influence weather patterns in the Southern Hemisphere, including the Australian region, in the opening week of October. What is the Southern Annular Mode? The SAM is an index that monitors the position of the westerly winds […]
A clear La Niña signal is starting to emerge in the central Pacific Ocean, however the declaration of La Niña depends on a few factors that are still a coin flip chance of occurring. What is La Niña? La Niña is the cool phase of the El Niño Southern Oscillation (ENSO) that occurs when cooler […]
An outbreak of severe thunderstorms will develop across much of WA during the middle of this week, with the potential for damaging winds and unseasonably cold and wet conditions following it. This dynamic thunderstorm period will be generated by a low pressure trough sitting across western WA and a deep low pressure system which will increase activity […]
Rain, wind and waves are intensifying along the north coast of NSW as a low pressure system starts to form off the coast. An upper-level trough passing over NSW has caused widespread rain over eastern Australia during last couple of days. The heaviest rain during the 24 hours to 9am on Friday fell along the […]
Rain, thunderstorms and a wintry airmass are impacting WA today, with signs that a low pressure system could generate severe weather next week. A low pressure system in the Bight is extending a cold front across southern WA on Friday morning with another low pressure trough in the Kimberley bringing rain and thunderstorms to northern […]
A burst of heavy rain and blustery winds will continue to batter eastern NSW over the next three days, with the state’s northeast coast set to see a particularly dangerous mix of rain, wind and surf on Friday and Saturday. An upper-level trough interacting with a feed of tropical moisture caused rain to spread across […]
Thursday is going to be a wild day for Sydneysiders, with an uncomfortable mix of gale force winds, the wettest day since June 2024, and a feels-like temperature as low as 6°C all on the forecast. The combination of a strong and icy southerly change and a thick rainband is behind the wintry weather […]
There are growing signs that heavy rain and potentially damaging winds will impact parts of eastern NSW later this week, while some other parts of the state could see unexpected low-level snow on Thursday. An upper-level cut-off low pressure system is expected to drift over NSW from Thursday and linger over eastern Australia for several […]
More than 80% of Australia could see rain this week as a surge of tropical moisture spreads across the country, causing wet weather from the Kimberley to Tasmania. A slow-moving upper-level trough will cause clouds, rain and thunderstorms to gradually spread across Australia from northwest to southeast this week. This system will deliver rain to […]
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 […]
