Australian authorities said Tuesday that more evacuation orders may be issued as relentless rains pummeled the country’s east coast, with several regions in Sydney’s west facing the worst floods in half a century. The wild weather system pounding New South Wales (NSW) over the last three days was expected to gather more strength in the next 24 hours thanks to the combination of a tropical low over northern Western Australia and a coastal trough off the east. “Overnight, unfortunately, some weather conditions have worsened, and those weather conditions are likely to worsen during the day so many communities will experience increasing heavy rainfall,” NSW Premier Gladys Berejiklian told reporters. Berejiklian said 15,000 more residents may need to be evacuated soon after authorities moved 18,000 to safe zones Monday.Severe flooding in Sydney, March 22, 2021.With 38 disaster areas declared in the state, authorities Tuesday described the next 24 hours as critical, as fast-moving flood waters overflowed riverbanks and inundated houses, farms and bridges across large swathes of the state. Though the weather system is likely to start easing starting late Wednesday, officials warned that residents may not be able to return to their homes immediately as incessant rains dump more water in river catchment areas. “Some of you may be wondering why you can’t go back home because it’s a sunny day. It’s because conditions are unsafe for that to occur,” Berejiklian said. Neighboring Queensland was also bracing for heavy showers Tuesday in the southern parts of the state, with the weather system expected to shift south to parts of Victoria and the island state of Tasmania over the next few days. About 10 million people in all states and territories except Western Australia will be affected by the extreme weather, the weather bureau said, with NSW and Queensland expected to bear the brunt of the system.
