There is little chance of drier weather in the near future, as wild weather is anticipated to once again affect southern Queensland and northern NSW.
According to the Bureau of Meteorology’s climate update on Wednesday, the negative Indian Ocean Dipole (IOD) phenomena would likely cause “most of Australia” to experience “above average rainfall” until December.
According to “all climate model outlooks surveyed,” adverse IOD conditions are predicted for the rest of the winter and the upcoming spring.
In parts of Australia, winter and spring rainfall is above average during the IOD’s negative phase.
The Bureau also stated that there is a 50% possibility of La Nia developing later in 2022.
La Nia is also connected to above-average winter-spring rainfall for northern and eastern Australia.
According to the Bureau, this is “twice the usual likelihood.”
A triple La Nia, which is highly rare, was predicted to occur again for the summer of 2022–2023, according to studies on ocean currents conducted by climate modeling centers throughout the world.
La Nia was officially announced in Australia over a month ago.
An east coast low this week may have caused erratic winds and surf conditions in southeast Queensland and northern NSW, which might lead to erosion in sensitive regions.
Along the southern Queensland coast starting on Wednesday and the northern NSW coast starting on Friday, the Bureau forecasts destructive wind, enormous surf, and heavy rain.
The prediction comes as many communities in and around Sydney are still getting over severe flooding, some of which have happened twice and three times just this year.
While the majority of the anticipated rain is predicted to fall offshore, localized increases in creek and river levels are probable.
According to BOM Senior Meteorologist Jonathan How on Wednesday, “This system is predicted to bring big seas combined with the danger of severe winds across exposed coastal fringes of southeastern Queensland.”
Beginning on Wednesday and moving into New South Wales on Thursday, strong southeasterly winds will develop along the Queensland coast south of Mackay.
According to Mr. How, there is a chance of destructive wind gusts of more than 90 km/h around the exposed coastal edges of southern Queensland and then northern NSW on Friday and early Saturday.
On Friday, a dangerous swell is anticipated to begin to form around the coasts of southern Queensland and northern NSW and last into the weekend.
According to Mr. How, the swell “may cause coastal erosion in sensitive regions along the southern Queensland and northern NSW coasts.”
With temperatures hitting 23 in the capital of Queensland, Brisbane and the Gold Coast will start to see the sun breaking through the clouds starting on Sunday.
However, the likelihood of anything other than cloudy days in Sydney over the next week is slim.
With low temperatures expected to stay between 10 and 13C over the coming week, the high-pressure system lingering over NSW is expected to prolong a run of chilly days.
In Victoria, the Bureau said that on Wednesday, certain areas of Melbourne had their coldest dawn in four years, with temperatures falling below zero.
