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.

While southeastern states are basking in spring warmth today, a surge of unseasonably cold air is approaching from Antartica with temperatures set to plummet over several states and territories.

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.

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 […]
