Torrential Rainfall and Flooding Warnings Across NSW and Queensland

A significant weather event is unfolding across eastern Australia, with the Bureau of Meteorology issuing multiple warnings for heavy rain, flooding, and damaging winds. The past 24 hours have seen intense rainfall spread along the coast of New South Wales, impacting areas such as Sydney and the Central Coast. Notably, Sydney’s Observatory Hill recorded over 100mm of rain since 9am yesterday, indicating the severity of the weather system.

As the rain continues to intensify, the NSW State Emergency Service has advised residents to stay indoors and remain vigilant for severe weather alerts, particularly in regions from Morisset to Bega. Premier Chris Minns emphasized the importance of avoiding unnecessary risks, especially when it comes to traveling through floodwaters.

Meanwhile, the weather system is expected to move southeast towards the Tasman Sea by Sunday, according to the BOM’s Steve Bernasconi. Heavy rainfall is anticipated to persist, with potential 24-hour totals ranging from 70mm to 120mm, and even up to 300mm in certain areas like the Blue Mountains and the Illawarra Escarpment.

The ongoing rain event has already caused major flooding concerns, with the Warragamba Dam reaching over 96% of its supply capacity. Water NSW’s chief executive, Andrew George, explained that the dam could potentially spill over by Monday, requiring significant rainfall accumulation ranging from 100mm to 150mm.

Furthermore, the coastlines of New South Wales and Queensland are on high alert for heavy downpours and flash flooding. The combination of a coastal trough and an inland low-pressure system has created a volatile mix, leading to widespread rainfall and the potential for damaging gusts along the coastal strip.
