What's happening now
Super typhoon Champi is in the Philippine Sea at 14°N, 139.2°E, moving west-northwest at 19 km/h. The latest reading, at 00:00 UTC on 19 October, records sustained winds of 250 km/h and gusts of 288 km/h, with a central pressure of 926 mb. Champi strengthened from typhoon to super typhoon since the previous reading at 18:00 UTC on 18 October, when winds were 222 km/h and pressure was 942 mb. The current wind speed matches the strongest recorded value in the readings on file, also recorded at 00:00 UTC on 19 October. The latest reading names no nearby town or distance from land.

How Champi developed
11–12 October — Movement changes direction
The first reading recorded no movement at 9.5°N, 163.8°E. Later readings showed movement first towards the south-west and south, then towards the south-east and north-east. Speeds ranged from 7 to 12 km/h once movement was recorded. Winds remained at 28 km/h throughout this period.
13 October — Winds rise to 37 km/h
At 00:00 UTC on 13 October, sustained winds increased from 28 to 37 km/h, with gusts rising from 32 to 43 km/h. The depression was at 9.3°N, 164.4°E and moving north-north-west at 18 km/h. The next reading kept the same wind speeds.
13–14 October — Track turns westward
Readings from 13 October at 06:00 UTC through 14 October at 00:00 UTC show movement shifting from north-west to west and then west-south-west. Recorded speed increased from 13 to 24 km/h across those readings. Sustained winds held at 37 km/h, with gusts of 43 km/h.
14 October — Winds reach 56 km/h
At 12:00 UTC, sustained winds rose from 37 to 56 km/h and gusts from 43 to 64 km/h. The reading recorded a central pressure of 1,003 mb, the only pressure value on file. TWENTY-NI was at 9.6°N, 161.2°E and moving north at 17 km/h.
15 October — Strengthens into a tropical storm
At 12:00 UTC on 15 October, Champi’s sustained winds reached 65 km/h, up from 56 km/h six hours earlier, and its classification changed from tropical depression to tropical storm. The reading also recorded gusts of 75 km/h and central pressure of 1,001 mb. This is the strongest wind reading in the available history.
16 October — Strengthens into a typhoon.
At 18:00 UTC, Champi’s sustained winds reached 139 km/h, with gusts of 160 km/h and a central pressure of 984 mb. The previous reading, six hours earlier, recorded tropical-storm strength with 111 km/h winds and 992 mb pressure. The latest position was 11.9°N, 150.2°E, over open water.
17 October — Strengthens into a super typhoon.
At 06:00 UTC on 17 October, Champi was a typhoon with winds of 213 km/h and pressure of 948 mb. At 12:00 UTC, winds reached 222 km/h and pressure was 945 mb. By 18:00 UTC, Champi was classified as a super typhoon, with winds of 241 km/h and pressure of 934 mb.
18 October — Weakens to a typhoon.
At 06:00 UTC, Champi was a super typhoon with winds of 241 km/h and pressure of 931 mb. By 12:00 UTC, it was a typhoon with winds of 222 km/h and pressure of 943 mb. The latest reading records a 19 km/h drop in wind speed and a 12 mb rise in pressure.
19 October — Strengthens again into a super typhoon.
At 18:00 UTC on 18 October, Champi was a typhoon with winds of 222 km/h and pressure of 942 mb. By 00:00 UTC on 19 October, the reading classified it as a super typhoon, with winds at 250 km/h and pressure at 926 mb. The new reading records the storm’s strongest wind speed on file.
How Champi is behaving
The wind record shows two increases: from 28 to 37 km/h on 13 October, then from 37 to 56 km/h on 14 October. The latest gust reading is 64 km/h. Central pressure is 1,003 mb in the latest reading, but the earlier readings contain no pressure values, so they cannot establish whether pressure fell or rose. A pressure trend would help assess how the system is changing; one measurement cannot show that trend.
The motion record is variable. TWENTY-NI began nearly stationary, then moved in changing directions before tracking generally westward from 13 October into 14 October. Recorded speeds during that westward stretch rose as high as 24 km/h. The latest reading shows a shift to northward movement at 17 km/h. These observations describe the track and wind changes, but do not identify the atmospheric conditions behind them.
How to track Champi
Turn on the tropical storm tracks layer in RainViewer to follow TWENTY-NI's recorded path. Each track point shows the storm's category at that moment: tropical depression points are cyan, tropical storm points are blue, category 1 points are yellow, category 2 points are amber, category 3 points are orange, category 4 points are red, and category 5 points are dark red. Every reading on this track identifies TWENTY-NI as a tropical depression, so its points use the tropical depression colour.
Watch how the track reflects the changing direction and the latest northward movement, alongside the recorded rise in wind speed from 28 to 56 km/h. The readings also show the limits of what the track can tell you: the pressure appears only in the latest reading, so the points do not show a pressure trend. Open RainViewer on Google Play or the App Store to follow the storm's track.
How TWENTY-NI fits the western Pacific typhoon season
The readings place TWENTY-NI in the western Pacific in October. October falls within the basin's active tropical-cyclone season. In general, warm ocean water can provide energy for tropical systems, while atmospheric conditions can help thunderstorms organise around them. Those are broad seasonal factors, not measurements of this depression: the readings contain no sea-surface temperatures, moisture values or wind-shear data. They do not establish why TWENTY-NI formed where it did.
Typhoon Megi reached Category 5 in October 2010, and Typhoon Hagibis reached Category 5 in October 2019 before making landfall. Both provide season-and-basin context, not close track comparisons. Their peak categories describe the strongest stages they reached, not the strength of TWENTY-NI, which remains a tropical depression in the readings here. The available record does not support a comparison of their development or eventual paths with this storm.
Storm FAQ
What does TWENTY-NI's 64 km/h gust mean?
A gust is a brief increase in wind speed, while the sustained wind reading describes the storm's steadier wind. TWENTY-NI's latest reading lists gusts of 64 km/h and sustained winds of 56 km/h.
Where can I find official warnings for TWENTY-NI?
RainViewer's storm readings do not include official warnings. Check your national weather service for official warning information.
Why are tropical storms given names?
Names give people a clear way to distinguish one tropical cyclone from another when several systems are being discussed. TWENTY-NI is the designation shown in these readings.
