According to Miriam Bradbury, a senior meteorologist at the Bureau of Meteorology, “Showers and storms are persisting across the far southwestern regions of the state as a low-pressure trough advances.”
Bradbury further explained, “These showers and storms have the potential to cause heavy rainfall, which may result in flash flooding. It’s important to be aware that riverine flooding is already widespread across much of the state.”
The bureau is monitoring a low-pressure system, referred to as 29U, positioned over the Coral Sea. There is a 25 percent likelihood of it evolving into a tropical cyclone by Thursday or Friday, with the possibility of making landfall between Cairns and Mackay.
Additionally, two tropical lows are located north of Western Australia. One, identified as 28U, is just south of Christmas Island, while the other, 30U, is off the Kimberley coast. Both have a 25 percent probability of developing into tropical cyclones by Thursday.
A fourth system, 31U, has emerged in the Gulf of Carpentaria. It is predicted to move westward over the Northern Territory and currently holds a low chance of transforming into a tropical cyclone.
Regardless of whether they become cyclones, multiple low pressure systems combined with a monsoon trough means widespread cloud, rain and thunderstorms for northern Australia this week, according to Weatherzone.
“Some computer models also suggest that at least one of this week’s eastern low pressure systems will drag heavy rain over central and southeast Queensland towards the end of the week,” Ben Domensino from Weatherzone said.
“If tropical cyclones do develop this week, parts of northern and eastern Australia could experience intense rain, flash flooding, damaging to destructive winds, large waves and coastal inundation.”
Australia has already had nine tropical cyclones form this season, which extends from November to April.
The next four tropical cyclones will be named Narelle, Oran, Peta and Riordan.
