Severe Tropical Cyclone Ruby

9 – 15 December 2021


A tropical low formed in the Solomon Sea on 9 December and travelled very slowly to the southeast over the next few days. The tropical low gradually developed, reaching category 1 tropical cyclone strength on the morning of 12 December. Later that night Ruby intensified into a category 2 tropical cyclone, increasing in speed as it continued its motion towards the southeast. Around midday EST on 13 December Ruby moved out of the Australian region (160°E). Tropical Cyclone Ruby maintained its intensity, at category 2, as it travelled directly over New Caledonia on 14 December. Wind gusts of 137 km/h were recorded at Touho and at Thio.

Tropical Cyclone Ruby occurred a significant distance from the Australian mainland and was short-lived as a tropical cyclone in the Australian area of responsibility.

Tropical Cyclone Ruby was the second tropical cyclone in the Australian region for the 2021/22 season.
