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 […]
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 […]
An East Coast Low is expected to form off the NSW coast this weekend, with heavy rainfall, powerful winds, erosive surf and cold temperatures forecast. An East Coast Low (ECL) is a type of low pressure system that forms close to the east coast of Australia and stays close to shore for at least 24 […]
The BoM has officially placed Australia on a La Niña watch, less than a month after El Niño was officially declared over. “There are some early signs that a La Niña might form in the Pacific Ocean later in 2024,” the BoM reported in its May 14 update. “As a result, the Bureau’s ENSO [El […]
The NSW coast can expect another week of rain as eastern Australia remains stuck in a stagnant pattern of wet and stormy weather. A stubborn high pressure system centred to the south of Australia has been driving moisture-laden winds into eastern Australia over the past week. This wet weather pattern is expected to linger for […]
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 […]
