A remarkably dry airmass over central Australia will move east over the next 72 hours, bringing dangerous fire weather to NSW over the weekend. The map below shows the parched air sitting over parts of WA, the NT, SA and Qld on Thursday morning. Image: 2m Dewpoint and 10 metre wind observations at 9:30am […]
There are early indications that a tropical cyclone could form near the Solomon Islands next week, with some forecast models suggesting the system could briefly enter Australia’s area of responsibility. Australia’s official tropical cyclone season runs from November until April. During this 6-month period, we typically see around 9 to 10 tropical cyclones forming […]
Winds are a key component to understanding the behaviour of bushfires. But what happens when the wind suddenly changes direction? Typically, a fire will tend to spread along the same direction as the prevailing winds. In a strong wind, this allows the fire front to follow the wind very quickly and can exceed 50km/h in […]
This year’s positive Indian Ocean Dipole is gaining strength so quickly that it’s getting close to the record-challenging 2019 event that underpinned Australia’s warmest and driest year on record. While the Pacific Ocean’s El Niño has been getting a lot of attention in recent months, its lesser-known cousin – the Indian Ocean Dipole (IOD) – […]
Australia’s tropical cyclone season will be affected by one of the strongest El Niño events in recent decades. So, how many tropical cyclones will Australia see this season? Australia’s official tropical cyclone season runs from November until April. While tropical cyclones can form in or near the Australian region at any time of year, […]
One of the world’s most consistent thunderstorms developed for the first time this season, signalling that the ‘build up’ across the north has begun. The image below shows the famous thunderstorm developing to Darwin’s north on Thursday afternoon. Image: Himawari satellite image at 3:15pm on Thursday, October 5. Nearly every afternoon the thunderstorm forms […]
Australia has had its driest September on record, led by huge rainfall deficiencies in the Murray-Darling Basin. Most of the country was well above average for maximums too, with NSW, Victoria and WA setting new records. Rainfall Australia as a whole averaged a measly 4.8mm of rain during September, the lowest on record for September […]
Thunderstorms have developed in southeast Qld and northeast NSW on Thursday, bringing a risk of heavy rainfall to the region. The storms are being triggered on a southerly change which is moving up the Qld coast on Thursday afternoon. The video below shows the storms moving slowly across the region. On Wednesday night, over half […]
It was Geraldton’s hottest September day in more than a century. Temperature records are being broken in WA today as a searing air mass spreads across the state’s north and west. A high pressure system centred over the Great Australian Bight is causing a pool of hot air to intensify over northwestern Australia, with temperatures […]
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 […]
