WELLINGTON, New Zealand (AP) — Australia's prime minister cautioned that the fallout from a vicious tropical storm over the weekend was “far from over” as parts of two states remained inundated with perilous floodwaters on Monday, even as the initial threat from the deluge continued to recede.

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 early Saturday with the strength of an Atlantic tropical storm.

Tropical storm Alfred could cause significant flooding in eastern Australia despite the slowly moving storm no longer being a cyclone.
