Summary
Tropical Cyclone Lili was a short-lived, small, late season, category one tropical cyclone that moved from the Banda Sea into the Timor Sea causing heavy rain to some islands in Indonesia's eastern District and to Timor Leste.
Lili originated from a tropical low that formed over the Banda Sea on 5 May. It moved to the south and gradually developed, passing through the southern Maluku Islands of Leti, Sermata and Babar overnight on 8 to 9 May. Heavy rainfall caused significant flooding in some parts.
The circulation intensified during 8 May and tropical cyclone intensity is estimated at 0600 UTC 9 May in the Timor Sea. Scatterometry confirmed the small region of gales about the centre, concurrent with development of deep convection near the centre. Lili weakened quickly on 10 May due to dry air eroding deep convection on the northern side. A low to mid-level ridge to the south steered the weakening circulation to the west northwest towards Timor Leste where it dissipated upon landfall on 11 May. Flooding was reported in parts of Timor Leste resulting in three deaths, one missing person, 72 damaged houses and three damaged bridges.
Lili was named by Jakarta Tropical Cyclone Warning Centre (TCWC) on 9 May just prior to moving into the Australian region near 9°S 129°E. International products were issued by BMKG Indonesia through the Jakarta Tropical Cyclone Warning Centre for the duration of Lili's time as a tropical cyclone.
