Tropical Cyclone Narelle has developed in the Coral Sea, marking the start of a period of heightened vigilance for communities in the Southern Hemisphere. This cyclone, part of the region's typical cyclone season from late October to May, is being closely monitored by the Joint Typhoon Warning Center.
