Tropical Cyclone Lili was a small and relatively weak off-season tropical cyclone that brought moderate impacts to the Maluku Islands and East Timor, and mild impacts to other parts of eastern Indonesia and far-northern Australia. It was the latest tropical cyclone to exist in the Australian Bureau of Meteorology's northern tropical cyclone region on record, surpassing Severe Tropical Cyclone Verna of 1977. Lili was the tenth tropical cyclone of the 2018–19 Australian region cyclone season, and the second of which to be named by the Indonesian Agency for Meteorology, Climatology and Geophysics. Lili originated from a tropical low that formed over the Banda Sea on 4 May 2019. The system gradually organised as it tracked slowly southwards, and strengthened into a Category 1 tropical cyclone
