What's happening now
Typhoon Choi-Wan is over open water at 42.5°N, 156.7°E, moving 35° at 70 km/h. RainViewer’s latest reading, from October 7 at 06:00 UTC, records maximum sustained winds of 130 km/h, gusts of 150 km/h and pressure of 964 mb. Choi-Wan is currently classified as a typhoon in the western Pacific basin. The storm is weakening compared with the previous reading: wind speed has decreased from 139 km/h to 130 km/h, while pressure has risen from 959 mb to 964 mb. Choi-Wan reached its strongest recorded intensity as a super typhoon on October 4, with winds of 250 km/h and pressure of 912 mb. The latest reading gives no nearby town, region, country or named water body, so no more specific location is known from the available observations.

How Choi-Wan developed
September 28 — First reading as a tropical depression
Choi-Wan first appears in the record as a tropical depression with 28 km/h winds and 32 km/h gusts at 15.0°N, 157.0°E. The initial reading shows no movement. The system has no recorded location name, so the observation places Choi-Wan over open water with nothing named nearby.
September 28 — Begins moving west
Six hours later, Choi-Wan is moving at 6 km/h on a bearing of 251°. The depression has 37 km/h winds and 43 km/h gusts at 14.9°N, 156.7°E. Later readings turn the movement farther west, with bearings from 270° to 289° through September 29.
September 29 — Westward movement reaches 16 km/h
Choi-Wan continues west across the open-water track, reaching a recorded movement speed of 16 km/h at 12:00 UTC. The depression holds 37 km/h winds and 43 km/h gusts while its position shifts to 15.6°N, 153.3°E. The available readings show no change in classification.
September 30 — Strongest recorded reading
The latest reading records Choi-Wan's highest wind speed so far: 46 km/h, with gusts of 53 km/h. Central pressure is 1,005 mb at 15.6°N, 151.9°E. The tropical depression is moving west at 12 km/h. No later observation is available in the current record.
September 30 — Strengthens into a tropical storm
At 12:00 UTC, Choi-Wan reaches tropical-storm strength with sustained winds of 65 km/h and gusts of 75 km/h. The reading records pressure at 1,002 mb and places the storm at 16°N, 151°E, moving west-northwest at 7 km/h. This is the strongest wind reading on file.
October 2 — Strengthens into a typhoon
At 12:00 UTC on October 2, Choi-Wan's wind reached 130 km/h, with gusts of 150 km/h and central pressure of 981 mb. The reading places the storm 126 km off Northern Mariana Islands in the Philippine Sea at 17.7°N, 144.6°E. This is the strongest reading in the record.
October 4 — Strengthens into a super typhoon
CHOI-WAN reaches super typhoon strength at 12:00 UTC with winds of 250 km/h and gusts of 288 km/h. Pressure falls to 914 mb, down from 924 mb 6 hours earlier, while the storm moves at 15 km/h on a heading of 5°. The reading places the centre at 23.3°N, 146.9°E.
October 5 — Weakens to a typhoon
At 06:00 UTC, CHOI-WAN’s sustained wind speed decreased to 213 km/h from 241 km/h six hours earlier, while gusts decreased to 245 km/h. The central pressure rose from 916 mb to 928 mb. The latest reading classifies CHOI-WAN as a typhoon after its super typhoon classification in the preceding readings.
How Choi-Wan is behaving
The nine readings keep Choi-Wan at tropical-depression strength throughout the record. Wind speed rises from 28 km/h initially to 37 km/h for most of the sequence, then reaches 46 km/h in the latest reading. The final observation also gives a central pressure of 1,005 mb, but earlier pressure values are not available, so the pressure trend cannot be established. The final six-hour interval therefore shows a measured increase in wind, while the available data do not establish whether the system is organising or coming apart.
Choi-Wan starts stationary, then moves generally westward. The recorded bearing changes from 251° to 289° before settling at 270° in the final reading, while forward speed varies from 6 km/h to 16 km/h and ends at 12 km/h. The position changes from 15.0°N, 157.0°E to 15.6°N, 151.9°E over 48 hours. The track shows a westward-moving tropical depression, but the readings do not provide enough information to assess wind shear, moisture, sea-surface temperature or the storm's internal structure.
How to track Choi-Wan
Open the tropical storm tracks layer in RainViewer to follow Choi-Wan's recorded path. Each track point is coloured by the storm's category at that moment: cyan for a tropical depression, blue for a tropical storm, yellow for category 1, amber for category 2, orange for category 3, red for category 4 and dark red for category 5. Every point on this track represents the classification recorded at that time, not a forecast.
Choi-Wan's points show an initial stationary reading followed by westward movement, with the latest point at 15.6°N, 151.9°E and a tropical-depression classification. Compare the point times, wind speeds and movement values to see how the track developed through September 28-30. RainViewer displays radar updates every 5 minutes.

What Choi-Wan's western Pacific setting means
Choi-Wan is part of the 2026 western Pacific season and is recorded in late September. Tropical systems in this basin commonly develop over warm tropical ocean waters, where humid air and the planet's rotation can support a closed circulation. The readings alone do not identify the conditions that formed Choi-Wan, and they contain no measurements of sea-surface temperature, moisture or wind shear. The available record establishes only the system's classification, winds, pressure, position and movement.
Several western Pacific storms provide historical comparisons without being direct matches for Choi-Wan. Typhoon Haiyan in 2013 reached category 5 intensity and later made landfall. Typhoon Bopha in 2012 also reached category 5 intensity before making landfall. Typhoon Mangkhut in 2018 reached category 5 intensity and later made landfall. These storms were far stronger than Choi-Wan's highest recorded classification, so the comparison is limited to the same basin rather than intensity.
Storm FAQ
What does tropical depression mean for Choi-Wan?
A tropical depression is the lowest listed tropical-cyclone classification in this record. Choi-Wan remains in that classification, with the latest reading showing 46 km/h maximum sustained winds and 53 km/h gusts.
What is the difference between Choi-Wan's wind and gust speed?
The wind value is the storm's maximum sustained wind speed in the reading, while a gust is a brief stronger burst of wind. Choi-Wan's latest reading lists 46 km/h winds and 53 km/h gusts.
Why do tropical storms receive names or designations?
Names and designations give each tropical system a clear identity in weather information and help distinguish one system from another. Choi-Wan is the designation used for this system in the 2026 western Pacific season record.
What does 1,005 mb tell us about Choi-Wan?
The 1,005 mb value is the central atmospheric pressure recorded for Choi-Wan in the latest observation. Earlier pressure readings are not available, so this page cannot establish a pressure trend.
