The Tonga Meteorological Service has issued its first Tropical Disturbance Formation Advice for system TD10F, warning that while the disturbance does not currently pose a direct threat to Tonga, it will continue to track south and away from the country over the next 24–48 hours.
In an advisory released at 8pm on Sunday, 22 March 2026, officials confirmed that TD10F was located near latitude 12.9° South and longitude 160.5° East, positioned approximately 390 km south of Honiara in the Solomon Islands.
The system was also measured at distances of 2,585 km west of Niuafo‘ou, 2,795 km west of Niuatoputapu, 2,810 km west‑northwest of Vava‘u, 2,795 km west‑northwest of Ha‘apai, and 2,745 km west‑northwest of Nuku‘alofa at 4pm Sunday.
According to the advisory, the potential for TD10F to develop into a tropical cyclone within the next 48 hours remains low.
However, the system will continue to move southwestward and is expected to maintain a path that keeps it well away from Tonga’s island groups.
A track map released with the advisory shows the system shifting gradually southwards, with its projected movement keeping it outside Tonga’s forecast zone.
The Tonga Meteorological Service will issue its next update at 8am on Monday, 23 March 2026, and is continuing to monitor TD10F closely for any changes in intensity or direction.
Residents are encouraged to stay informed through official advisories as the system moves further southwest.
