This weekend, a storm system expected to affect all of Australia is expected to deliver further precipitation and gloomy skies to all major cities.
From Friday, central and northeast Queensland are expected to be battered by persistent rain that will send heavy rain all the way down to northeast NSW.
A rain belt is anticipated to develop from that moist weather system and continue east into Brisbane.
A wide-spread storm ranging from Queensland’s central coast to NSW’s north will form on Saturday morning while a second cyclone in NSW moves northward into the Sunshine State.
The south coast of Queensland and the north coast of NSW may see perilous conditions as a result of the rain, according to Weatherzone meteorologist James Rout.
The greatest gusts, which might gust to 80 km/h and produce waves as high as 6 metres, are expected to emerge on Friday night and Saturday morning, the forecaster added.
Sydney is expected to have heavier rain and storms into late next week.
Sydney and the Illawarra area of New South Wales may see windy weather.
In regions that are already wet, flooding might result from the severe rain, Mr. Rout cautioned.
Southeast Queensland and northeast NSW might see floods tonight and tomorrow early, he warned.
Particularly the Northern Rivers in NSW and the Darlings Downs and Granite Belt in Queensland, “Inland areas should be on alert for moderate floods.”
Mr. Rout asked locals in these areas to pay attention to flood warnings.
On Saturday afternoon, the rain in Queensland will stop, but by Saturday night, spiralling winds will have sent heavy rain towards the central coast of New South Wales.
The storm is expected to deliver windy and hazardous conditions while centering over Port Macquarie.
Newcastle, Lismore, and Moree are predicted to see light rains.
On Sunday morning, the storm system will start to dissipate, but until late next week, southerly winds will continue to bring light showers to Canberra and the Blue Mountains.
Up to nine days of rain are possible in Sydney until the rain stops late next week.
On Wednesday, southerly and easterly winds will subside before a fresh system approaches Sydney from the west on Thursday, according to Mr. Rout.
According to him, a high pressure system is predicted to lessen the rain on Sunday and bring a few days of bright weather to Sydney.
In the south, Melbourne is expected to get a few light showers on Friday morning before they subside in the afternoon.
Similar conditions are predicted on Saturday, with early light rains fading throughout the afternoon.
Beginning the next week, the city is anticipated to remain gloomy with lowest temperatures below 10C and high temperatures in the middle of the teens.
Beginning on Friday afternoon, a low pressure system and trough will bring heavy rain to the coast of Western Australia.
The system will develop into a rain band throughout the course of the next night. It will travel slowly eastward over Saturday and Sunday as it passes across Alice Springs.
Some places are expected to get up to 25mm of rain from the heavy rain system, which is expected to last many months.
Darwin will avoid the worst of the rain, but the weekend will be gloomy with a chance of light showers.
With light rains expected into the beginning of next week, Tasmania is expected to see the remnants of the QLD and NSW heavy rain system.
Adelaide will see part of the system’s cloud cover, but it is not anticipated to rain there.
While many devastated communities are still recovering from La Nina’s destruction, meteorologists have warned that a new wet-weather phenomenon called a Southern Annular Mode is on its way.
The Southern Annular Mode, or SAM, is a short-lived climatic driver, according to Mr. Rout.
It’s a belt of high pressure that circles the earth and may sometimes be seen sitting farther south or north.
It is now in a favourable position, blocking cold fronts from entering Australia farther north and concentrating rainfall on the country’s south and east.
About two weeks are anticipated for SAM’s favourable situation.
With portions of the states expected to get more than 300mm in the next four weeks thanks to the favourable SAM, NSW and ACT should anticipate a very wet start to spring.
