24 January - 1 February 2021
Best Track of Tropical Cyclone Lucas
All times shows are in Australian Eastern Standard Time (AEST), that is UTC + 10 hours.

Tropical cyclone Lucas began in the Gulf of Carpentaria as a low-pressure system on 24 January. It moved across the Cape York Peninsula into the northern Coral Sea region on 29 January. The low-pressure system took another two days to develop into a tropical cyclone on 31 January. By this time, it was well off the Australian coast to have an impact on the mainland or island communities.

Lucas continued moving eastwards and intensified to a category 2 cyclone during the night on 31 January. The system maintained this intensity as it moved across the Coral Sea and to the east of the Eastern Region boundary [160 degrees East] on 1 February.

The system cloud structures began to weaken the next day as Lucas turned south-eastwards. It continued this path before weakening below category 1 system on 4 February, just south of New Caledonia.


Solomon Advisories were issued for possible gales to affect the southern islands, Runnell and Bellona, as Lucas moved eastwards just to the south of the group.
