Unnamed 01U

27 July - 1 August 2022


An unusual out of season tropical low in the Indian Ocean briefly reached tropical cyclone intensity on 29 July over open waters.

Gales developed to the south of the centre overnight from 28 to 29 July extending to the northwest quadrant during 29 July sufficient to reach tropical cyclone intensity. Gales continued southwest of the centre on 30 and 31 July even as the circulation weakened.

Ocean wind warnings and track maps were issued for the system but gales were not expected to extend more than halfway around the centre. It was not named in real time on the basis of anticipated weakening. However, upon reanalysis after the event it was determined that it did attain tropical cyclone intensity.

The system passed west of Cocos Island and while it did lead to a period of heavy showers, there were no significant impacts on the Islands.
