Flash Floods and Heavy Rain in Australia: NSW and QLD Weather Update (2026)

Australia's Wild Weather Weekend: A Coastal Battle Against the Elements

As heavy rain and storms batter the New South Wales (NSW) coastline, the forecast for the coming days paints a picture of a wet and wild weekend across multiple states. With rainfall exceeding 100mm in some areas, the impact of these extreme weather events is being felt by communities and emergency services alike.

But here's where it gets controversial: while some regions are experiencing severe storms, others are facing a different kind of challenge. Let's dive into the details and explore the contrasting weather scenarios across Australia.

The NSW Coastal Deluge

Parts of the NSW south coast, including Moruya and Bodalla, received an incredible amount of rainfall overnight on Friday, with over 100mm recorded. The weather system is now moving northward, bringing showers and thunderstorms to the Illawarra, Sydney, Central Coast, and Hunter regions. Senior meteorologist Dean Narramore predicts these areas could see 30-50mm of rainfall, with isolated falls reaching up to 100mm.

And this is the part most people miss: heavy storms hit the north Parramatta area on Saturday morning, dumping an astonishing 35mm of rain in just half an hour. This intense rainfall caused flash flooding in Mona Vale and Palm Beach, with about 750 SES volunteers responding to the impact of these thunderstorms.

The NSW State Emergency Service (SES) has received over 880 requests for assistance in areas affected by the wild weather. Acting Assistant Commissioner Sonya Oyston urges people to remain vigilant, as heavy rain and storms are expected to continue for the next 48 hours. With many catchments becoming saturated, the risk of flash flooding remains high across the coast and ranges.

A Tale of Two Coasts

While NSW battles heavy rain and storms, Victoria is recovering from a severe downpour that dumped 180mm of rain in just six hours on Lorne and Wye River. This extreme weather event triggered flash flooding along the Great Ocean Road, causing significant damage to campgrounds and sweeping away vehicles and tents.

The contrast between these two coastal regions is stark. While NSW braces for more wet weather, Victoria is experiencing a respite from the severe downpours. Narramore predicts isolated showers and thunderstorms for far-eastern and northeast Victoria, but conditions are generally easing.

The Climate Crisis Connection

The World Meteorological Organization's recent statement highlights the increasing vulnerability of Australia to extreme weather and natural disasters due to the climate crisis. With surface air temperatures averaging 1.48C above pre-industrial levels, the past three years have seen a continuation of extraordinary global temperatures. This trend underscores the urgent need for global action to address climate change.

As we navigate these challenging weather conditions, it's important to stay informed and take necessary precautions. The impact of these extreme weather events on communities and the environment serves as a stark reminder of the importance of climate resilience and adaptation.
