Tropical Cyclone Uesi

4 – 14 February 2020

Summary

Uesi was a system that tracked southwards across the Coral Sea and caused wind gusts equivalent to a category 2 tropical cyclone as it moved into the Tasman Sea and passed close to Lord Howe Island on 13 and 14 February 2020. Tropical cyclone Uesi also caused abnormally high tides and large waves along the New South Wales and southeast Queensland coast and about Lord Howe Island.

The tropical low that became Uesi was first identified and tracked in the northeast Coral Sea, south of the Solomon Islands, on 4 February. The system initially moved slowly in the northeast Coral Sea before forming into a tropical cyclone to the west of Vanuatu on 9 February. Uesi reached a peak intensity of category 3, northwest of New Caledonia, on 11 February and then gradually reduced to category 2 intensity as it moved into the southern Coral Sea during 12 February.

As Uesi started to approach Lord Howe Island on 13 February it started to lose some of its tropical characteristics, but maintained winds equivalent to a category 2 tropical cyclone as it passed close to the island that night. There were reports of damage to buildings and boats and the local White Terns were affected as the Norfolk Island Pines they nest in were brought down.

Maximum wave heights of 5-6 metres were generally recorded along areas of the southeast Queensland coast during the event. Large waves extended down the New South Wales coast and led to some beach closures.
