Climate change has been blamed for severe weather warnings issued for parts of New South Wales, Queensland and Victoria as heavy rain, thunderstorms and flash flooding is expected to rip through the east coast over the next few days.
Millions of residents along the east coast are being urged to prepare for heavy rainfall, thunderstorms and potential flooding heading into the weekend.
Parts of New South Wales are forecast to receive more than one month’s worth of rain over the next three days.
“It’s very unusual for this much moisture to spread across Australia during the springtime,” Sky News meteorologist Rob Sharpe said.
“It’s all being enhanced by a waning negative Indian Ocean Dipole and a developing La Nina event. These two events are increasing moisture levels across Australia.
“Climate change is likely a factor in enhancing the rain totals due to the fact that warmer air can hold more moisture.”
The Bureau of Meteorology (BOM) issued the severe warning on Tuesday for NSW, Queensland and Victoria, urging residents to prepare for heavy rain, thunderstorms and the potential for flash flooding over the next few days.
On the other side of the country, Perth had its wettest November day on record with 41mm of rain and hail with Alice Springs also smashing its record with more than 90mm of rain on Tuesday.
BOM Hazard Preparedness and Response East Manager Jane Golding says severe weather from Queensland will go down through the western slopes in NSW and into Victoria.
“Heavy rain and thunderstorms are expected to set in from Wednesday and continue into the weekend, so we’re urging people to prepare now,” she said.
“Many areas in eastern Australia will see significant rainfall, and some locations in NSW and Queensland are likely to see daily rainfall totals of 150 millimetres or higher.
“This kind of heavy rainfall over a short period of time can cause dangerous flash flooding and combined with the fact that many river catchments down the east coast are already quite wet, there is a real risk that we may see some rivers flood too.
“Please make sure you’re staying up to date with current forecasts and warnings and be careful when you are out and about this week.”

Residents who live close to the Queensland border and along the western slopes should prepare for heavy rain and possible flooding as the state is forecast to receive more than a month’s worth of rain over the next three days.
“Flash floods are dangerous and can happen anywhere there is localised heavy rainfall,” NSW State Emergency Service tweeted on Wednesday.
“If you come across a flooded road, simply stop and turn back.
“Never drive, ride or walk through floodwater.”
Western Queensland is expected to see three times their November average rainfall in the coming days.
The greatest threat of flooding is in Queensland’s Darling Downs and Granite Belt and on the NSW Northern Slopes, according to Sky News meteorologist Rob Sharpe.
“For many of Australia’s farmers this event is bad news. It’s harvest time for much of the country and heavy rainfall can reduce yields significantly and delay harvest until drier weather arrives,” he said.
“However, for many regions of Queensland that are not harvesting, this is a good news story as it will help ease the long term drought conditions.”
Victorians are urged to prepare for gusty south-easterly winds, particularly across southern and mountain areas.
The BOM describes it as an “unusual wind direction” which is likely to bring down trees and powerlines as well as cause minor property damage.
Stay prepared by parking your car undercover and away from trees and check that loose items such as outdoor furniture, umbrellas and trampolines are safely secured.
