’Unstable air mass’ to bring storms
Ex-tropical cyclone Esther is finally expected to move away from Australia, leaving behind a trail of wet weather that will continue into the weekend for the east coast. And a new cyclone could be in the works which will bring even more moisture.
The system was only classified as a tropical cyclone for about one day before it downgraded as it moved from Northern Australia all the way to the southeast.
The ex-cyclone created a "500km wide rain band" as it made away across the country this week, leaving storms, heavy rain and flood in its wake.
It was expected to move into the Tasman Sea on Friday night and into Saturday morning but residents in the country's east can still expect to see some lingering rain this weekend.
Sky News Weather Meteorologist Alison Osborne said most of the wet weather will be centred around the coast.
"What we will see is a broad ridge moving along the NSW coast and eventually the Queensland coast which will generally keep showers across those eastern regions," she said.
"In NSW we will see showers and even storms across parts of the northern ranges from Saturday morning. However most of that rain activity will be camped across the ranges and not making it towards the west."
Ms Osborne said on Sunday a trough further north is expected to deepen and could cause storms around areas like Bourke and Moree.
Eastern Queensland is expected to see the heaviest rain over the weekend, having already copped a drenching throughout the week.
"There is a very humid and very unstable air mass over parts of eastern Queensland," Ms Osborne said.
"We will see some storms, some of them may be severe, delivering heavy rainfall which means that flash flood risk in eastern Queensland really hasn't moved away."
The Bureau of Meteorology (BOM) issued a severe thunderstorm warning for central and northern parts of the Queensland coast on Friday afternoon.
"Severe thunderstorms are likely to produce heavy rainfall that may lead to flash flooding in the warning area over the next several hours," the BOM said.
Areas that are likely to see heavy falls include Mackay, Proserpine, Charters Towers, Bowen, Collinsville and Mareeba.
Thunderstorms along the coast are expected to last until Sunday, with a major flood warning still in place for Balonne, Barcoo, Bullo, Paroo and Warrego rivers
There is also "increasing monsoonal activity" of the coast of northern Queensland into next week.
"A low is expected to develop near Cape York Peninsula before moving east into the Coral Sea next week," BOM said.
"We're watching the system for cyclone development."
