Sydney is experiencing a wet and unsettled day on Tuesday, 25 August 2026, as a major weather system moves across New South Wales. Forecast information released today indicates widespread rainfall across the state, with the potential for thunderstorms, heavy downpours, damaging winds and large hail in some areas.

For Sydney, around 5–10 millimetres of rain is forecast today. While the city is not expected to experience the most extreme conditions seen elsewhere in NSW, residents are being advised to remain alert because weather conditions can change quickly. Severe thunderstorms are possible across parts of the state, particularly around areas east of the Great Dividing Range.

The Bureau of Meteorology has warned of a broader risk of heavy rainfall and flash flooding in parts of NSW. Some inland and elevated areas could receive substantially higher rainfall totals, while thunderstorms may produce sudden heavy rain, strong winds and hail.

The unsettled weather is also affecting travel conditions. Motorists should expect wet roads and reduced visibility during heavier showers, while pedestrians and commuters may face delays if intense rainfall develops. Sydney residents are being encouraged to check updated weather warnings before travelling, particularly if they are heading outside the metropolitan area.

The weather system is part of a wider pattern affecting several parts of eastern Australia. NSW is among the areas expected to receive significant rainfall, with meteorologists monitoring the possibility of severe thunderstorms as the system moves through.

Today's forecast comes alongside other major Sydney developments, including ongoing disruption to train services following an overhead wiring failure near Chatswood. ABC News reported that the rail problem is causing delays and long lines for replacement buses during the morning commute.

For Sydney residents, the combination of wet weather and transport disruption means extra caution may be needed during today's commute. People travelling by road should allow additional time and drive according to conditions, while commuters using public transport should check service updates before leaving.

Authorities continue to monitor the weather system and issue warnings where necessary. Residents should remain alert for sudden changes, particularly if thunderstorms develop in or around the Sydney region.
