The maps show the predicted flood extent for the most at-risk areas of Brisbane, based on Bureau of Meteorology forecasts.

Tropical Cyclone Alfred weakened into a tropical low Saturday as it neared Brisbane, Australia, bringing heavy rain and flooding risks to the region, according to officials. Initially expected to make landfall as the first cyclone to strike southeast Queensland since 1974, Alfred's winds dropped to under 39 mph (63 kph) as it shifted inland.

Significant damage and power outages are possible in the densely populated region of Queensland, where tropical cyclones impacts are not uncommon but direct landfalls are.
