A blocking-high pressure system will park itself directly over Tasmania this week, and is forecast to become so strong, it challenges an Australian record. High pressure is crossing the Great Australian Bight after a cold front swept over southeastern Australia this weekend. While high pressure is common after a cold front, this particular high pressure […]
Early last month, we said that May would be a make-or-break month for the positive Indian Ocean Dipole (IOD) that could be forming this year. Turns out, it has most likely broken. A positive IOD occurs when the trade winds along the equator blow to the west instead of the east, causing an upwelling of […]
Massive waves reaching nearly 6 metres impacted the NSW coast on Sunday, with damaging waves continuing to impact the central coastline on Monday. A Tasman Low is behind mammouth southeasterly swell along the eastern seaboard and it’s not going anywhere fast, with the large waves set to continue until mid-week. The satellite images below show […]
A Tasman Low pressure system will whip up large and powerful swell for several days from Saturday, with the potential to impact port operations along the eastern seaboard. The images below show that a stubborn high-pressure system will cradle the low and keep it over the Tasman Sea between Saturday and Wednesday. Images (top […]
Huge 24-hour rainfall totals have again been recorded in and around Sydney region, with over 200 mm of rain recorded at some spots to 9 am Friday. The rain was heaviest in the Illawarra region just south of Sydney, with extremely heavy falls also recorded in the Southern Highlands, most of which lies in the […]
The Illawarra has endured heavy rainfall overnight and this morning, with the deluge set to continue and spread north into the Warragamba catchment on Thursday. The persistent rainfall is being caused by an upper low pressure system over NSW, which has caused a surface trough and low to deepen over the Tasman Sea. A continuous stream […]
Rain, and plenty of it, is forecast to drench areas south and west of Sydney on Thursday, with isolated accumulations of up to 250 mm possible within 24 hours in some spots. Weatherzone meteorologist Ashleigh Madden wrote on Tuesday about the eastward-moving upper level low pressure system that could deliver a deluge to parts […]
Rain is set to increase on Wednesday, with hundreds of millimetres in just two days possible for the Illawarra and South Coast regions. An upper-level low will cause rain to spread over eastern Australia in the next three days, with the possibility of heavy falls in NSW and Vic. The satellite image below shows […]
Sydney endured its second wettest June day on record on the weekend as a bombing low pressure system rapidly intensified off the NSW coast. The radar animation below shows heavy and persistent rain hammering central eastern NSW on the weekend. #Sydney‘s 142.6mm during the last 24 hours was the city’s heaviest daily rain in […]
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 […]
