Millions of residents on Australia’s southeast coast are facing a prolonged period of heavy rainfall that threatens flash flooding, as a tropical cyclone slowly tracks toward the nation’s third-biggest city.

Alfred was 245 kilometers (152 miles) east of Brisbane and moving toward the coast at 10 kilometers per hour, according to the Bureau of Meteorology. The Category 2 cyclone is forecast to make landfall very early Saturday morning, later than earlier expectations.
