More than 18,000 people have been evacuated from their homes in Australia’s New South Wales (NSW) as heavy rains and major flooding continue to inundate the state, causing some areas to resemble “inland seas.”

Rains have been impacting communities since Thursday but flooding intensified over the weekend, with images showing roads, trees and houses completely submerged in floodwaters in some areas.

Up to 38 places across the state are regarded as natural disaster areas and 19 evacuation orders have been issued, with potentially more to come, NSW Premier Gladys Berejiklian said in a news conference Monday.

Much of the flooding has hit the mid-north coast, from Hunter Valley near Sydney to Coffs Harbour, but severe weather warnings have also been extended to include districts on the state’s south coast for Tuesday as the rains are forecast to shift. Heavy rainfall is also developing inland in the north of the state Monday, while in the east, the Australian Bureau of Meteorology has warned of “life-threatening” extensive flooding and heavy rain.

A severe weather warning has also been issued for neighboring Queensland, with heavy rains likely bringing flash flooding to southern and western parts of the state.

‘Breaking point’

Homes that were ravaged by wildfires during Australia’s record bushfire season in 2019 and 2020 are now being affected by the floods.

“Communities who were battered by the bushfires are now being battered by the floods and a deep drought prior to that. I don’t know anytime in our state’s history where we’ve had these extreme weather conditions in such quick succession in the middle of a pandemic,” said NSW Premier Berejiklian.

“You’ve been through three or four incidents which are life changing on top of each other. It can make you feel like you are at breaking point.”

Some locations have seen close to a meter (39 inches) of rain since Thursday, and increasing rainfall of 50-100 mm (2-4 inches) is expected across the Sydney region over next 24-36 hours, Bureau of Meteorology’s Jane Golding said in a news conference Monday.

The worst-affected areas have seen rain totals up to five times the March monthly average falling in just four days.

The huge rainfalls have been driven by two weather systems colliding, she said. A “slow moving coastal trough” and the approach of another system coming through from the west is pumping down tropical moisture into the state, which is then being whipped up by strong easterly winds.

“With this approach of this new system coming from the west which is approaching today, we’re expecting this heavy rain to fall in areas that haven’t seen as much rain over the last few days, and we’re expecting the flood risk to develop in those areas as well,” Golding said.

Residents have been urged to monitor the weather warnings and heed the advice of emergency services.

Since Thursday, the State Emergency Service (SES) has responded to 8,000 calls for assistance, according to Berejiklian. Thousands of emergency workers and volunteers are on the ground, helping trapped residents.

Overnight, residents in Kempsey were told to evacuate as the Macleay River is expected to burst its banks, according to CNN affiliate Nine News. The town is currently split in two by the floodwaters and there is no access to the city center, Nine News reported.

BOM’s national flood services manager, Justin Robinson, said in a news conference Monday the extreme weather is a record-breaking “state-wide flood event” and flooding on the Hawkesbury River, which runs north and west of Sydney, is as bad as a similar 1961 incident.

“I’ve been a flood forecaster in the Bureau for 20 years and this is probably the worst flooding that I’ve experienced and have had to forecast,” he said. “We’ve got a flood watch that covers all the way from the Queensland border down to the
