Tropical Cyclone Alfred: Moreton Bay flood maps show risk

With Moreton Bay in the firing line of Tropical Cyclone Alfred, there are several parts of the city at risk of storm tide and flood/overland flow inundation.

Mayor Peter Flannery says low-lying coastal and canal properties are at risk.

“We’re concerned about the storm surges on top of a high tide which is predicted between Thursday night and Friday morning, when the cyclone is supposed to come over. It could be a double-whammy there,” Mayor Flannery says.

“We’re trying to inform those low-lying communities – Bribie Island, Meldale, Toorbul, Donnybrook, Beachmere, a bit of Redcliffe at the northern end and the southern end as well. They could be in for a lot of rain, a lot of wind, and also an increase in sea levels through there.

“We’ve been told it (the storm surge) could be anywhere from nothing to 0.5m to 0.8m.”

“We’ve put that on our public disaster dashboard modelling, so people can zoom into their properties and see the impact on their property.

“Hopefully that will inform them to make a decision to stay or move – go to family or friends or if need-be a refuge centre.”
