Rain intensifies in both Queensland, NSW and the west as we head into the weekend
Let's start with the eastern one, which will be another significant rain system for Queensland, particularly in the southeast near the coast.
If you are in between Brisbane and Mackay, please keep up to date with the latest forecasts and warnings, as a low develops off the coast, fed by tropical moisture, resulting in heavy rain.
The rain should start to spread across much of Queensland and northern NSW during the day on Friday. A nice drop from this one, rather than widespread intense rain.
The activity intensifies on Saturday along the coast with modelling suggesting widespread falls of 25mm to 100mm. Locally up to 300mm in the most affected area near the low, which is currently between Maryborough and Yeppoon.
This one is relatively fast though, with the weather rapidly easing again on Sunday.
High pressure brings a dry weekend to the southeast, but in the west of the country we have the next big system move through.
Again this will have a good feed of moisture from the tropics - the Indian Ocean - ensuring that the rainband that moves through with the gusty cold front is moisture-laden and brings 25mm to 50mm to the southwest corner, before slowly decreasing as you head inland.
This is a strong cold front, and will be accompanied by the usual wind threats. Most of this is felt later Saturday into Sunday.
These are ongoing examples of weather systems meeting up with tropical moisture to bring heavier than usual rain for those in the path of the low, trough or front.
The global patterns in both the Indian and Pacific Oceans tell us when this injection of moisture is more likely - when we are in a Negative Indian Ocean Dipole (IOD) or a La Nina.
Put simply, a Negative IOD is the Indian Ocean equivalent of La Nina, just without the fancy name. They both act to push extra moisture towards Australia.
We crossed the threshold into a Negative IOD about a week and a half ago, and remain there this week. Most forecasts have us remaining below that threshold for the next month or two. If we remain there for about eight weeks in total it will officially be a Negative IOD.
The Pacific Ocean has weak signs of heading towards that negative threshold too - ie a La Nina. It is one to watch to see if we have both oceans enhancing our moisture over the next few months.
It won't ensure rain for all though - only those in the path of the lows.

Grim news for more than half of Australia
Much of Australia can expect a wetter than usual spring, with the Bureau of Meteorology predicting above average and potentially record-breaking rainfall for most of the eastern two-thirds of the country from August through November. Senior climatologist Lynette Bettio said for August to October, there would be 'likely wetter-than-average conditions' for most of the eastern two-thirds of mainland Australia. 'There is around an equal chance of rainfall being above, below, or near average for most of Western Australia and the far southeast,' Dr Bettio said. The bureau has highlighted a possible shift in the Indian Ocean Dipole (IOD), a key ocean temperature pattern strongly influenced by warming oceans and which greatly affects Australian weather. Warmer, wetter nights are forecast across much of Australia this spring. NewsWire / Damian Shaw Credit: News Corp Australia The coming months also look warmer than normal, especially overnight. 'Daytime temperatures for August to October are likely to be above average for northern, western, and southeastern Australia, with below-average daytime temperatures likely for the interior and some eastern parts of the country,' Dr Bettio said. 'This is consistent with the wetter-than-average forecasts and associated cloud cover. 'Night-time temperatures are very likely to be above average for most of Australia.' Across much of the eastern half of the country, there's also a high chance of unusually warm nights. 'For August to October, waters around much of Australia are forecast to remain warmer than average to the north, south, and east,' Dr Bettio said. The Indian Ocean Dipole plays a key role in shaping Australia's spring rainfall outlook. Image: Bureau of Meteorology Credit: News Corp Australia From September to November, the odds of above-average rainfall remain strong, with a 60 per cent to greater than 80 per cent chance across the eastern two-thirds of the country. There's also an increased risk of unusually high rainfall, in the top 20 per cent of historical records, for parts of eastern Queensland, NSW, southeastern South Australia, and northern Victoria. This period also marks the transition from the dry to wet season in northern Australia, typically bringing higher humidity, more storms, and regular showers. But not every region will share in the rain, with below-average totals more likely in western parts of Western Australia and southwestern Tasmania. Experts predict wetter-than-average conditions for much of eastern Australia this spring. NewsWire / Damian Shaw Credit: News Corp Australia While the IOD, a climate driver that can strongly influence rainfall, is currently neutral, the bureau expects it to shift into a negative phase from August to November before returning to neutral in December. This phase often boosts rainfall over southern and eastern Australia, though without a La Nina in the Pacific, the wettest possible outcomes are less likely. July 2025 recorded the warmest sea surface temperatures for the month since records began in 1900, continuing a run of record or near-record warmth since mid-2024. These warm oceans can help feed moisture into weather systems, increasing rainfall potential. Warmer sea surface temperatures continue to influence Australia's seasonal weather patterns. Image: Bureau of Meteorology Credit: News Corp Australia Despite some recent showers, drought conditions persist in parts of SA, Victoria, Tasmania, and WA. More sustained falls will be needed to break long-term dry spells. 'In summary, we're likely to see a wetter-than-average August to October for most of the eastern two-thirds of mainland Australia, roughly equal chances of above or below-average rainfall for most of Western Australia and the southeast, and above-average daytime and night-time temperatures for most of the country,' Dr Bettio said.

Four dead, more than 50 missing in India flash floods
At least four people are dead and more than 50 are missing after surging floodwaters swept through a village in the northern Indian Himalayan state of Uttarakhand. Teams from army and disaster response forces had reached the area, local authorities said, with workers trying to rescue people trapped under debris and sludge, authorities added. TV news channels showed water, mud and debris surging down a mountain, sweeping away homes and a road. The mudslide cleaved through Dharali village, burying some houses, according to a video update shared by the state chief minister's office. "A massive mudslide struck Dharali village in the KheerGad area near Harsil, triggering a sudden flow of debris and water through the settlement," the Central Command of the Indian Army said in a post on X. "About a dozen hotels have been washed away and several shops have collapsed," said Prashant Arya, an administrative officer who added that rescuers including Indian army and police were searching for the missing. Uttarakhand Chief Minister Pushkar Singh Dhami said rescue agencies were working "on a war footing." "We are doing everything possible to save lives and provide relief," he said in a statement. Uttarakhand is prone to floods and landslides, which some experts blame on climate change. At least 200 people died in 2021 when flash floods swept away two hydroelectric projects in the state. There are about 10,000 glaciers in the Indian Himalayas, and many are receding due to the warming climate. with AP At least four people are dead and more than 50 are missing after surging floodwaters swept through a village in the northern Indian Himalayan state of Uttarakhand.
