A massive northwest cloudband is starting to spread rain across about 80 percent of Australia, including much-needed falls in drought-affected areas of southern Australia. A cut-off low pressure system will interact with a stream of tropical moisture over the next four to five days, producing one of the biggest rainbands Australia has seen in recent […]
Parts of southwestern Australia endured their coldest day in 3-6 years on Monday following the passage of a cold front, with another burst of cold air on the way this Thursday. A cold front crossed southwestern WA on Sunday evening and Monday morning, bringing widespread rainfall of 20 to 40 mm across the south and […]
Australia’s alpine regions have seen a number of cold fronts during June and July delivering the best July snow depth in four years, maintaining steady levels of hydro electrical power. The depth at Spencers Creek (elevation 1830m, roughly halfway between the NSW resorts of Perisher and Thredbo) was around 160cm late last week. Here’s how […]
A broad cloudband of tropical origins is stretching across much of NSW, bringing chilly daytime temperatures and low solar energy generation. The satellite imagery below shows a broad area of cloud extending across much of NSW on Tuesday. The temperature observation overlaid shows the mercury struggling to exceed the low-teens, with alpine and tableland areas […]
The Southern Annular Mode (SAM) has reached its most positive value in close to two years – but has impacted Australia’s industries in a different way than usual. What is the Southern Annular Mode? All year round, a belt of powerful winds flows around the Southern Hemisphere surrounding Antarctica. This wind belt flows from west […]
Wind turbines are usually pictured on rolling hills far from cities and people, but what if they were on rolling swells off the coast of populated areas? Australia’s National Electricity Market (NEM) and WA renewable power network currently harnesses wind power from 115 wind farm facilities and a capacity of 15,617 MW, according to OpenNEM. […]
The East Coast Low lashed large parts of the NSW coastline in the 24 hours to Wednesday morning as damaging to destructive winds, intense rainfall and large waves disrupted industries from aviation to ports, and transport to power utilities. The stretch of NSW coastline from the Hunter region to the South Coast has been most […]
Heavy rain, destructive winds and damaging surf will batter eastern NSW in the coming days following the explosive development of an East Coast Low leading to significant disruptions to transport, aviation and utilities.

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 […]
