Close to a metre of rain has fallen in parts of eastern NSW over the last four days, with several rivers currently experiencing major flooding. So, how unusual was this rain event from a historical perspective? A slow-moving low pressure trough and East Coast Low produced hundreds of millimetres of rain between the Illawarra […]
An exceptionally wet start to July that produced 1.5 months’ rain in just four days has continued Sydney’s wettest year-to-date on record. A stream of moisture-laden air feeding into a coastal trough and East Coast Low produced a lengthy spell of heavy rain over central eastern NSW during the last four days. This […]
The East Coast Low that brought heavy rainfall, flooding, damaging winds and surf to parts of NSW on the weekend has weakened, with conditions expected to ease later today.

La Niña has had a surprising impact on shipping operations in NSW this year, with increased freshwater outflows from flooded rivers affecting the behavior of ships entering some ports.

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 […]
