Wati's final recorded position was 184 km off the Cook Islands, where the tropical storm was moving southeast at 33 km/h. The last reading, at 06:00 UTC on October 19, 2026, placed its centre at 20.7°S, 156.8°W. Sustained winds were 83 km/h, gusts were 95 km/h, and pressure was 999 mb. Wati had weakened from a category 1 cyclone, its strongest recorded stage, with 120 km/h winds on October 17, to a tropical storm by October 18. The latest readings show further weakening: sustained winds fell from 102 km/h at 00:00 UTC on October 19 to 83 km/h six hours later, while pressure rose from 992 mb to 999 mb. Wati has ended, and its feed will not receive further updates.
No active watches or warnings.
13 October — First recorded as a tropical depression
The first reading places ONE at 6°S, 164.5°W with sustained wind of 37 km/h and gusts of 43 km/h. The recorded movement is 0 km/h. This is the beginning of the available track, not a measure of when the system first formed.
14 October — Track turns from south-westward to southward
At 06:00 UTC, the depression is moving on a 236° bearing at 7 km/h. Six hours later, the recorded bearing is 162° and the speed is 12 km/h. The readings show a marked change in direction while sustained wind remains 37 km/h.
15 October — Sustained wind reaches 46 km/h
At 00:00 UTC, ONE remains a tropical depression, but its sustained wind has risen from 37 km/h to 46 km/h. Gusts are 53 km/h. The reading records movement at 14 km/h on a 130° bearing.
15 October — Sustained wind rises to 56 km/h
At 12:00 UTC, the depression’s sustained wind increases to 56 km/h, with gusts of 64 km/h. The previous reading recorded sustained wind of 46 km/h. The classification remains tropical depression in the available observation.
16 October — ONE reaches tropical-storm strength
At 06:00 UTC, the latest reading classifies ONE as a tropical storm, with sustained wind of 65 km/h and gusts of 75 km/h. The reading also records pressure of 999 mb and movement at 13 km/h on a 164° bearing.
17 October — Strengthens to a category 1 cyclone
At 12:00 UTC, Wati was a tropical storm with sustained winds of 111 km/h and gusts of 128 km/h, at 14.4°S, 163.0°W, moving south at 15 km/h. By 18:00 UTC, it had reached category 1 strength, with winds of 120 km/h, gusts of 138 km/h and pressure of 985 mb, at 14.8°S, 163.2°W, moving south at 17 km/h.
18 October — Weakens from a category 1 cyclone to a tropical storm.
At 06:00 UTC, Wati was a category 1 cyclone with 120 km/h sustained winds, 138 km/h gusts and 984 mb pressure. By 12:00 UTC, it had weakened to a tropical storm, with 111 km/h winds, 128 km/h gusts and 988 mb pressure. The readings place the change over open water.
ONE’s sustained wind rises through the record, from 37 km/h in the first readings to 65 km/h in the latest one. The classification changes from tropical depression to tropical storm at that final observation. Gusts rise from 43 km/h to 75 km/h over the same period. These readings show increasing wind speed, but they do not reveal the storm’s internal structure or establish how well organised it is.
The pressure record has only one value: 999 mb at 06:00 UTC on 16 October. A pressure trend cannot be calculated from that single measurement. Recorded movement varies from 0 to 14 km/h before the latest reading of 13 km/h. Bearings change over the track, shifting from south-westward readings early on to a generally south-south-eastward direction in the more recent observations.
Turn on the tropical storm tracks layer to follow ONE’s recorded path in RainViewer. Each track point is coloured to show the storm’s category at that moment: tropical depression is cyan, tropical storm is blue, category 1 is yellow, category 2 is amber, category 3 is orange, category 4 is red, and category 5 is dark red. The points show recorded stages along the track, rather than a forecast.
ONE’s latest reading places the storm over open water, with no nearby place named in the record. Compare the latest track point with earlier points to see how its position, direction and recorded category have changed. Open RainViewer on Google Play or the App Store to follow ONE’s track and check its latest recorded position. For official warnings, consult your national weather service; this page does not carry advisory data.
Names help distinguish one tropical cyclone from another and make communication about a storm clearer. The readings provided for ONE do not explain how this system received its identifier.
Central pressure is the air pressure measured near the centre of a cyclone. A single value describes pressure at that observation time; it cannot show whether pressure is rising or falling without earlier measurements.
A bearing measures direction clockwise from north. A movement bearing of 164° points just east of due south.
