Millions of residents along Australia’s eastern coast are bracing for the arrival of a very slow-moving storm, the strongest tropical cyclone to threaten the region in more than 50 years. Tropical Cyclone Alfred is expected to make landfall late Friday or early Saturday with the strength of a category 1 Atlantic hurricane,

Cyclone Alfred stalled off Australia’s east coast on Thursday as officials shut airports, schools and public transport while residents stockpiled supplies and sandbagged homes against flooding expected when the category-two storm hits.

Australia braced for a rare east coast tropical cyclone that is swirling towards Brisbane, its third-most populous city, with authorities urging residents in flood-prone suburbs to evacuate soon.
