Heavy rain during La Niña triggers floods and evacuations in Australia’s southeast

LA Times  

A woman is rescued from floodwaters in Maribyrnong in northwest Melbourne, Australia, on Friday. “So this has only just started.” Andrews said 4,700 homes were without power, more than the 3,500 that the Victoria State Emergency Service had reported earlier Friday. North of Victoria, moderate to major flooding was occurring along several rivers in inland New South Wales state, home of Sydney, the bureau said. “Fortunately, the Murrumbidgee River peaked on Thursday, and we’re starting to see the floodwaters decline in those areas,” New South Wales State Emergency Service official Andrew Edmunds said. Sydney, New South Wales’ capital and Australia’s largest city, last week beat its 1950 record to make 2022 its wettest year ever.
