Sydney breaks annual rainfall record

With 86 days left in 2022, Australia's largest city, Sydney, has broken its annual rainfall record.

The city has received more than 2200mm of rain since January, Australia's weather agency said.

Widespread flooding across Australia, driven by a La Nina weather pattern, has already killed more than 20 people this year, the BBC wrote on Thursday.

People in Sydney have been warned of immediate flood risks and to prepare for another wet summer.

"We've seen a lot of rain in Sydney today but it's only going to get worse," New South Wales Emergency Services Minister Steph Cooke said on Thursday.

Sydney's previous rainfall record of 2.194mm was set in 1950.

More rain and storms are forecast in the coming days, but reservoirs are full, dams are full and rivers are already swollen, the Bureau of Meteorology said.

This means that many areas are primed for flash flooding.

"Our message to the community in the coming days is to start preparing," said forecaster Gabrielle Woodhouse. "[This flood] looks like it's going to be more significant than what we've seen over the last 12 months."
