A week-long deluge of floods and thunderstorms in Australia’s eastern states is expected to ease after being battered by heavy rain and winds. The storm caused Sydney to experience heavy rain, hail, and winds, leading to 200 calls for help to the NSW State Emergency Service (SES) on Saturday night. The Bureau of Meteorology issued a severe weather warning for heavy rainfall, damaging winds, and large hailstones in parts of NSW.
Although the warning was later cancelled, Sydney can expect a high chance of showers on Sunday afternoon, with the possibility of a thunderstorm. A lingering low-pressure trough has caused showers and thunderstorms in eastern and southern areas, resulting in flooded rivers and the need to rescue some people. The trough is expected to move offshore late on Sunday and into Monday, bringing relief.
Scattered showers and isolated thunderstorms across the NSW-Victorian border area may ease and move eastwards throughout the day. Flood warnings for Victoria’s Thomson and Avon rivers have been downgraded, but further rainfall could cause moderate renewed rises. The bureau warned of possible heavy rainfalls in Gippsland on Sunday morning, with a chance of a thunderstorm in the northeast. Parts of eastern Victoria are predicted to record additional rainfalls of 100mm across the weekend on top of the 200 to 300mm received since Wednesday.
