- The NSW State Emergency Service (SES) received nearly 900 calls for help, including flood rescues and a camper rescue in the Snowy Mountains.
- Heavy rainfall totals included 130mm in two hours at Pearl Beach and 93.5mm in one hour at Ettalong, causing flash flooding.
- Hazardous surf warnings are in place along multiple NSW coasts, with waves averaging two meters high and described as ‘very gnarly’ by locals.
A relentless onslaught of ‘very dangerous’ thunderstorms and colossal waves has gripped New South Wales, transforming idyllic coastlines into tumultuous seascapes and bringing tragic consequences. As of Saturday, January 17, 2026, over 20 beaches across the state have been forced to close, with some, like Cronulla, literally vanishing under a powerful, two-meter swell. The wild weather has claimed one life, triggered flash flooding, and prompted nearly 900 calls for emergency assistance, painting a vivid picture of a state battling nature’s fury.
The devastating impact of the storms became tragically clear southwest of Sydney, where a woman lost her life. She was a passenger in a car on the Illawarra Highway at Macquarie Pass when a falling tree struck their vehicle around 4 p.m. on Saturday. While the male front-seat passenger sustained minor injuries and two rear passengers were unharmed, the woman died at the scene. Macquarie Pass was subsequently closed for hours as emergency crews worked tirelessly, highlighting the immediate and life-threatening dangers posed by the severe weather system, as reported by Yahoo News.
NSW Beaches Engulfed: The Vanishing Shorelines
The dramatic closure of numerous beaches underscores the sheer power of the ocean’s response to these storms. Popular coastal havens such as Dee Why, Manly, Mona Vale, Narrabeen, Bronte, Clovelly, and Tamarama were among the more than two dozen shut down. However, it was Cronulla Beach that offered one of the most striking images of the storm’s intensity, with heavy swells submerging the entire shoreline, pushing waves crashing over the rock pool and against the foreshore wall. What does it take for a vibrant coastline to essentially disappear? The answer lies in a combination of persistent rainfall and monstrous waves, averaging two meters high, a stark contrast to the typical one-meter waves seen in recent weeks.
The conditions were so intense that even seasoned locals found themselves overwhelmed. Actor Patch May, visiting his childhood haunt at Cronulla Beach Rock Pool with his brother Mikey, described the experience as ‘very gnarly.’ Despite clinging to a wire rope barrier, a couple of massive waves knocked them off their feet. ‘It was an absolute washing machine,’ May recounted to The Sydney Morning Herald, emphasizing the raw, untamed power of the water. Both brothers, lifelong Cronulla residents, strongly advised anyone unfamiliar with the beach or lacking strong water safety skills to steer clear of the water during such perilous conditions.
Surfline’s live beach cameras provided a grim real-time assessment, revealing poor conditions across most NSW coastal areas. Bill, a surfer from Newcastle, noted the swell’s ‘lumpy, strong, and stormy’ nature. While it possessed immense power, he observed, ‘it is not good for surfing.’ This sentiment was echoed by Andrew Short, a beach scientist, who explained to The Sydney Morning Herald that such significant waves would likely begin reshaping beaches, potentially paving the way for more consistent surf conditions after a summer largely characterized by a ‘wave drought.’
Flash Floods and Widespread Warnings: Beyond the Coast
The dangers extended far beyond the immediate coastline. The ‘very dangerous’ thunderstorms brought with them the threat of flash flooding, a menace that quickly materialized in areas like Mona Vale and Palm Beach on Sydney’s northern beaches. Astonishing rainfall totals were recorded, with Pearl Beach receiving more than 130mm in just two hours on Saturday afternoon. Ettalong on the Central Coast saw 93.5mm of rain within an hour, while Cronulla South was hit with 67mm over two hours. These intense downpours led to a flurry of warnings from the NSW State Emergency Service (SES), urging residents in affected areas, including Sutherland, Engadine, Lucas Heights, Menai, Waterfall, Kurnell, Padstow, Mona Vale, Calga, Terrey Hills, Brooklyn, Spencer, and Woy Woy, to stay indoors and away from windows.
The SES has been working non-stop, responding to nearly 900 calls for help across Shoalhaven, Illawarra, Sydney, and the Blue Mountains. Their efforts included critical flood rescues for individuals trapped in vehicles by rapidly rising waters in locations such as Albion Park, Picton, and Marulan. In a separate incident, three campers, one suspected of suffering from hypothermia, required rescue from Geehi in Kosciuszko National Park in the Snowy Mountains overnight Friday, as reported by 9News. NSW SES acting assistant commissioner Sonya Oyston underscored the importance of vigilance, particularly for holidaymakers in unfamiliar surroundings, advising them to avoid setting up camps near waterways or under trees.
Meteorological Outlook: A Lingering Threat
The severe weather system, described as slow-moving, is expected to persist, keeping communities on high alert. Bureau of Meteorology Meteorologist Miriam Bradbury warned that while the risk of severe weather might gradually decrease, showers and thunderstorms are likely to continue through the weekend and into early next week. The immediate threat includes heavy falls, damaging wind gusts, and potentially large hail across eastern parts of New South Wales.
Hazardous surf warnings remain in effect for the Sydney Coast, Illawarra Coast, Bateman Coast, and Eden Coast, with authorities advising people to stay out of the water and avoid walking near surf-exposed areas. The broader meteorological picture reveals a complex system, with residual moisture from ex-tropical cyclone Koji potentially contributing to heavy rain in Northern Queensland and a tropical low increasing the likelihood of cyclone development in the Northern Territory. Meanwhile, other capital cities like Melbourne and Adelaide are bracing for warmer, sunnier conditions, a stark contrast to the stormy reality gripping NSW.
The sheer scale and intensity of this weather event in New South Wales serve as a potent reminder of nature’s unpredictable power, demanding not only immediate emergency response but also a sustained public awareness campaign for coastal safety and flood preparedness. The tragic loss of life and the dramatic reshaping of iconic beaches underscore the urgent need for communities to respect the elements and adhere to warnings, especially as climate patterns continue to challenge established norms.
