An estimated 20,000 properties across Brisbane could be impacted by flooding and storm surges in the wake of Cyclone Alfred.
Brisbane Lord Mayor Adrian Schrinner shared the update on the latest modelling and how the city could be impacted.
“The modelling shows almost 20,000 properties across Brisbane could be impacted by storm surge or flooding,” he said.
“These 20,000 properties could experience anything from minor inundation in their yards to significant flooding inside homes.
“According to the modelling, areas most at risk include Nudgee Beach, Brighton, Windsor, Ashgrove, Morningside, and Rocklea.”
The Bureau of Meteorology is expecting peak storm surges to occur from March 6 onwards.

Queensland, NSW on Flood Watch
In the Bureau of Meteorology’s latest update, the national weather agency says minor to major flooding is likely at the Mary River, Noosa River, Sunshine Coast rivers and creeks, Pine and Caboolture Rivers, Upper Brisbane River, Lower Brisbane River, Logan and Albert Rivers, Gold Coast Rivers and Creeks, and creeks in both Ipswich and Brisbane.“Rainfall associated with Tropical Cyclone Alfred has the potential to cause major flooding along Queensland coastal rivers from Maryborough to the New South Wales (NSW) border,” the Bureau’s warning says.
“Isolated flooding may develop from overnight (March 5), with more widespread flooding likely from overnight (March 6-7), continuing into early next week.”
The heaviest rainfall and most severe flooding will depend on the track of the cyclone system, which will approach the coast late on March 6 or March 7.
The heaviest rainfall will be to the south of the cyclone’s path.
High tides and large waves are expected to increase flood risk and impacts in low lying coastal areas.

Rapid river level rises and flash flooding are expected across many creeks, associated with the heaviest rainfall.
Widespread minor to major riverine flooding is possible.
Meanwhile, the Bureau says major riverine flooding is possible along the NSW Northern Rivers and Mid North Coast region from March 6.
“Rainfall associated with Tropical Cyclone Alfred may cause rapid river rises and extensive flooding along NSW coastal rivers from the Queensland border to Port Macquarie starting on [March 6] and continuing through the weekend,” it says.
Catchments likely to be impacted include the Tweed and Rous Rivers, Brunswick River and Marshalls Creek, Wilsons River, Richmond River, Clarence River, Orara River, Coffs Coast, Bellinger and Kalang Rivers, Nambucca River, Macleay River, Hastings River, Camden Haven River, and the Manning and Gloucester Rivers.
Green Day Cancels Gold Coast Show

“Hey Australia, unfortunately due to circumstances out of our control, (the March 5) Gold Coast show has been cancelled,” they said.
“With Cyclone Alfred bringing some seriously nasty weather, it’s just not possible to go ahead safely.
“We know this is a huge disappointment, and we’re just as bummed as you are. Stay safe out there!”
