A slow-moving tropical storm crossed islands off Australia’s heavily populated eastern coast late Friday, lashing coastal suburbs with destructive winds and dumping heavy rain across the region.

Ex-tropical Cyclone Alfred has been downgraded to a tropical low, as it approaches Australia’s eastern coast. Although the speed at which Alfred is travelling has slowed, Brisbane locals have been sent a stark warning of what might be to come.

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