Warmer weather on the way after NSW records iciest June in almost 20 years
Senior hydrologist at the Bureau of Meteorology (BoM) Dr Paul Feikema said warmer than average days and nights were expected for most of the country through to spring.
He said a wetter than average July to September was also likely for parts of inland and Northern Australia, with roughly equal chances of above or below average rain in the south east and west.

'July rainfall is likely to be below average across parts of Australia's south east and south west,' he said.
'Daytime temperatures for July to September are likely to be above average for much of the country. However, above average temperatures are less likely for inland areas, aligning with forecasts, wetter than average conditions and associated cloud cover.'
The averaged mean minimum temperature for June in New South Wales was 4.1C, or 0.51C below the 1961-1990 average, while it also experienced the lowest minimum temperature for the state since 2006, a BoM spokesperson said.
Three sites in NSW recorded their coldest June night on record, including Tumbarumba, on the edge of the Snowy Mountains, which fell to -8C, the alpine town of Khancoban, which fell to -4.5C, and Nowra, which dropped to 0.4C.
Canberra Airport also experienced its lowest daily minimum temperature on record, falling to a freezing 7.6C.
The area-averaged rainfall total in NSW for the month of June was just 21.4mm, 39% below the 1961–1990 average.
Queensland's averaged mean minimum temperature for June was 9.9C, some 0.1C below the 1961-1990 average and the lowest June minimum temperature for the state since 2012.
'Cold fronts as well as clear skies associated with high pressure systems resulted in cooler mornings for periods of June for parts of the east,' the BoM spokesperson said.
The Northern Territory also experienced its coldest June minimum temperatures since 2012, with mean minimum temperatures below or very much below average for large parts of the Territory, while Victoria was hit with its coldest June minimum temperatures since 2017.
Victoria's averaged mean minimum temperature was 3.75C, 0.52C below the 1961–1990 average.
Bendigo Airport had its coolest June day on record on 21 June, with a maximum temperature of just 6.3C, while Wangaratta in the state's north-east had its lowest June mean maximum temperature on record (12.6C).
Dean Narramore, a meteorologist at the BoM, said the cold weather was expected to continue in coming days, predicting a strong cold front with damaging winds, widespread rain and mountainous snow to come to south-eastern parts of Australia in the next 24 hours.
'We're seeing moderate to heavy falls to the Adelaide area and welcome rainfall for much of southern South Australia after what's been a very dry few months,' he said.
'Then it'll continue moving eastwards into western parts of Victoria this afternoon … that's going to bring widespread showers with local thunder and hail.'
Severe weather warnings were in place on Wednesday afternoon for the Flinders and Mount Lofty ranges, as well as western parts of SA, with winds in excess of 90km/h expected.
From Wednesday evening, the system was expected to sweep across to NSW and northern parts of Tasmania, bringing rain, wild winds and possible blizzards in alpine areas.
Overall, the national average mean temperature in June was 0.29C above the 1961–1990 average, largely due to mean maximum temperatures that were above average for Tasmania, western and northern SA, much of Western Australia and parts of the Cape York Peninsula in Queensland.
In WA, June's averaged mean maximum temperature of 23.6C was the seventh-warmest on record since national observations started in 1910.
Mean minimum temperatures were above average for parts of southern Australia and northern Queensland and below average across parts of the east and north of the country.

Alaska's Juneau orders evacuations as record glacier flood looms
Alaska's capital city of Juneau is urging many residents to evacuate, bracing for the arrival of what could be record floodwaters flowing downstream from a basin dammed by the area's Mendenhall Glacier, with the event being driven by climate change amid glacial retreat, according to a federal agency. Summer glacial flooding, known as a glacial lake outburst flood, or GLOF, threatens parts of the city due to a combination of rainwater and snowmelt. Authorities say flooding from the Mendenhall River will likely crest around 4pm Alaska time, or 8pm ET on Wednesday. They hope that recently installed emergency flood barriers will hold back the waters and protect Mendenhall Valley, where a majority of Juneau's 32,000 full-time residents live. On Tuesday morning, authorities confirmed water had started escaping the ice dam, with flooding expected into Wednesday. Some Juneau residents in the flood zone have already evacuated as officials intensified their warnings Tuesday, saying 'Don't wait, Evacuate TONIGHT.' The National Weather Service (NWS) office in Juneau said in an X post late Tuesday that local hydrologists had adjusted their Mendenhall flooding forecast, anticipating that the river would crest at over 16ft on Wednesday morning. Nicole Ferrin, with the NWS, said during a briefing on Tuesday that the flood warning was issued after 'a lot of analysis' but the calculations were complicated by rainfall causing significant rising of the lake and river and confirmed that a sub-glacial release had occurred. 'This will be a new record based on all of the information we have,' Ferrin said, according to the Juneau Empire. The Mendenhall Glacier fills a large valley north of Juneau, creating an ice dam for a meltwater lake that fills Suicide Basin. Since 2011, outburst floods from the depression have been pouring into Mendenhall Lake and rushing down the river toward Juneau each year. But the annual Mendenhall glacial lake outburst flood is judged to be intensifying as a result of climate change. The National Oceanic and Atmospheric Association (Noaa), said in a statement that Alaska has warmed twice as fast as the rest of the US over the last several decades. Over the last century Alaska's average annual temperature has risen 3.1 degrees Fahrenheit and the overall trend continues to increase, according to data from Noaa's National Centers for Environmental Information. Scientists have attributed the retreat, melting and thinning of glaciers over the last century to Earth's warming climate. Alaska's glaciers are among the fastest melting glaciers on Earth and have been in steep decline since the late 1980s, according to the Alaska Climate Science Center. On the record amounts of water now threatening Juneau, Rick Thoman, Alaska climate specialist at the Alaska Center for Climate Assessment and Policy, told Noaa reported: 'Without climate change, there is no reason to think that this would be happening on the Mendenhall Glacier, then in the lake, and downriver.' An outburst in August 2023 sent record amounts of water into Mendenhall Lake and down Mendenhall River toward Juneau, inundating areas that had not experienced flooding before, the NWS office in Juneau said at the time, causing significant erosion. The Mendenhall Glacier is about 12 miles from Juneau and considered a popular tourist attraction. Juneau lies 800 miles from Anchorage, where Donald Trump and Russian president Vladimir Putin are due to meet on Friday to discuss the war in Ukraine. Flooding from the glacier has become an annual concern for almost 15 years, and in recent years has swept away houses and swamped hundreds of homes. It is blamed on the retreat of a smaller glacier near Mendenhall Glacier – a casualty of the heating climate – and left a basin that fills with rainwater and snowmelt each spring and summer. When the water creates enough pressure, it forces its way under or around the ice dam created by the blue ice Mendenhall glacier. The Mendenhall was originally named Sitaantaagu ('the Glacier Behind the Town') or Aak'wtaaksit ('the Glacier Behind the Little Lake') by the Tlingit Indians, but later called Auke (Auk) Glacier, for the Auk Kwaan band of Tlingit Indians, by naturalist John Muir. It was renamed in 1892 for Thomas Corwin Mendenhall, who had helped determine the boundary between Canada and Alaska. It is considered a relic of the little ice age that lasted until the mid-18th century and is now receding at about 100 to 150 feet a year. The Associated Press contributed reporting.

Major US city braces for potentially catastrophic glacial flooding as officials urge residents to evacuate
Emergency managers are urging residents of Alaska 's capital, Juneau, to evacuate as glacial flooding from the Mendenhall River threatens to sweep through the city. Officials have recommended that residents within the 17-foot lake level inundation zone evacuate the area until the water recedes and an 'All Clear' message is sent via the wireless emergency alert system. In a Facebook post, officials said a glacial outburst has occurred at Suicide Basin, which is dammed by the Mendenhall Glacier that has experienced accelerated melting and retreat, primarily due to climate change. 'The basin is releasing, and flooding is expected along Mendenhall Lake and River late Tuesday through Wednesday,' they added. The river is expected to crest around 4pm local time on August 13 (8pm ET). Authorities are racing against the clock to protect Mendenhall Valley, where most of Juneau's 32,000 residents live. They are relying on two miles of emergency flood barriers installed just last month, though officials warn the swelling waters could overwhelm them. A large glacial outburst can release as much as 15 billion gallons of water, the equivalent of nearly 23,000 Olympic-size swimming pools, according to the University of Alaska Southeast and the Alaska Climate Adaptation Science Center. Nicole Ferrin, a meteorologist with the National Weather Service, said: 'This will be a new record, based on all of the information that we have.' This is a developing story... More updates to come. Many roads, including Mendenhall Loop Road, have been closed, along with facilities along the Mendenhall Valley Public Library, Diamond Park Field House, Diamond Park Aquatic Center and fields located along the river. 'The closure will remain in effect until water levels recede below 12 feet and bridge engineers complete a safety inspection,' officials said. A Red Cross shelter was set up for residents at Floyd Dryden Gymnasium.

Telstra is rocked by massive outage as customers are left in the dark
Thousands of Telstra customers in southern New South Wales were left without internet and phone coverage following a major outage. More than 100,000 services across mobile, NBN, ADSL and PTSN were disrupted about 1.45pm following a power issue at an exchange site in north Nowra. Crews were deployed to resolve the issue which affected 99 other base stations across the region, the ABC reported. Power has since been restored at the site and all services have since come back online, a Telstra spokesperson told the Daily Mail. 'Our team fixed an onsite power issue impacting mobile, NBN, ADSL and PSTN services on the NSW South Coast this afternoon,' they said. 'Services have been coming back online since 1:45pm and are now fully restored. 'Thanks for your patience while we got this sorted.' It is believed emergency calls were not affected by the outage, though a number of local businesses were reportedly affected by disrupted internet access. Last week, a separate Telstra outage affected thousands of customers across the state following a severe weather event.
