Flood watches have been issued between central Queensland and northeast New South Wales as unseasonably heavy rain continues to drench parts of eastern Australia. A deep layer of moisture-laden east-northeasterly winds interacting with a pair of upper-level low pressure systems is causing widespread rain over eastern Australia. This drenching kicked off on the weekend and […]
Several cold fronts will batter southern parts of Australia this week, bringing much needed rain to areas that have seen record low rainfall this year. During the last year, stubborn high pressure systems sitting over southern Australia have forced cold fronts and rain bearing systems south. This led to parts of South Australia, Tasmania […]
Parts of the Pilbara, Kimberley, WA’s interior, and inland SA are about to see a prolonged period of wet weather, as an upper-level trough moves over the region. The image below shows the upper-level trough over the Pilbara region on Friday night, which will slowly progress further east into central Australia on the weekend. Images: […]
Ongoing stratospheric warming above Antarctica looks set to influence weather patterns across the Southern Hemisphere into August as a strong negative Southern Annular Mode (SAM) takes shape. The atmosphere above East Antarctica started to warm abruptly during the middle of July. This warming initially started in the polar stratosphere, around 30-40km above East Antarctica, but […]
A Tasman low is whipping up blusterous southerly winds and large and powerful swell on Monday, likely impacting port operations in NSW. Waves peaked at 6 metres offshore of Eden on the NSW south coast at 4am Monday morning as the low whipped up a long southerly fetch and swell. Some other notable observations […]
Fierce winds are moving across parts of WA, SA, Vic, NSW and the ACT on Friday as two intense cold fronts sweep across southern Australia. The satellite image below shows the first cold front moving over SA and the other following closely behind in the Bight. Image: Himawari-9 satellite images at around 6:40am on Friday, […]
The coming weeks’ weather will be a mixed bag of severe weather and mild wintry weather, in response to a shift in the jetstream. Our planet’s jetstreams are bands of fast-moving air that sit about 10km above the surface. They typically flow from west to east and lie between regions of contrasting temperature. You […]
Perth has enjoyed its wettest 24-hour period in over a year, after 43.8 mm fell in the 24 hours to 9 am Thursday. Weatherzone meteorologist Ashleigh Madden wrote on Wednesday afternoon that a cold, wet change was heading the way of southwest SA, and the cold front duly arrived on Wednesday evening. As you can […]
Heavy rain has fallen in parts of Victoria overnight, with 100 mm recorded at two weather stations, and flood watches in places for several forecast districts. Several other locations across the state recorded falls in excess of 50 mm to 9 am Tuesday, as a low pressure system over the Tasman Sea directed moisture onto […]
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 […]
