What's happening now

Dujuan was a tropical storm over open water with nothing near it in its final reading, moving northeast at 54 km/h. The final position was 40.5, 154.2, at 2026-09-22 12:00 UTC. Dujuan had sustained winds of 111 km/h and gusts of 128 km/h. The final pressure was 975 mb. Dujuan had weakened from a typhoon after reaching its strongest recorded wind of 130 km/h on 2026-09-21 at 06:00 UTC. Dujuan’s pressure had risen from 970 mb at the strongest reading to 975 mb in the final reading. Dujuan has left the feed, so RainViewer will not add further observations to this storm page.

How Dujuan developed

  1. September 13 — Forms as a tropical depression

    Dujuan first appears as a tropical depression at 12.2°N, 156.1°E, with 28 km/h winds and 1,005 mb pressure not yet recorded. The system was stationary in the first reading, then began moving west and northwest during the following observations.

  2. September 16 — Strengthens into a tropical storm

    Dujuan reaches tropical-storm strength at 65 km/h, with gusts of 75 km/h and pressure of 994 mb. The storm is at 16.5°N, 149.5°E and moving northeast at 23 km/h. Wind speed rises to 74 km/h six hours later as pressure falls to 992 mb.

  3. September 17 — Reaches typhoon strength

    Dujuan becomes a typhoon at 120 km/h, with gusts of 138 km/h and pressure of 981 mb. The reading places the centre at 25.2°N, 146.0°E, moving northwest at 46 km/h. The storm had reached 111 km/h six hours earlier.

  4. September 18 — Weakens back to a tropical storm

    Dujuan falls to 111 km/h and is classified as a tropical storm at 25.1°N, 144.5°E. Pressure remains 981 mb, and the storm is moving northwest at 37 km/h. The next reading places it 107 km off Japan, in the Philippine Sea.

  5. September 18 — Regains typhoon strength

    Dujuan returns to typhoon strength at 120 km/h, with gusts of 138 km/h and pressure of 977 mb. The centre is at 26.2°N, 140.7°E, 152 km off Japan, in the Philippine Sea, moving west-northwest at 20 km/h.

  6. September 21 — Reaches its strongest recorded wind

    Dujuan reaches its strongest recorded wind of 130 km/h, with gusts of 150 km/h and pressure of 971 mb. The centre is at 33.7°N, 139.8°E, 63 km off Japan, in the Philippine Sea, moving northeast at 24 km/h.

  7. September 22 — Weakens to a tropical storm

    Dujuan is classified as a tropical storm at the latest reading, with 111 km/h winds, gusts of 128 km/h and pressure of 975 mb. The centre is at 39.0°N, 150.2°E, moving northeast at 48 km/h. The pressure is higher than at the previous reading.

How Dujuan is behaving

Dujuan’s readings show a sustained strengthening phase from September 15 through September 17. Wind speed rises from 46 km/h to 120 km/h while pressure falls from 1,003 mb to 981 mb. Meteorologists use falling central pressure alongside rising winds as evidence of a deepening, organising tropical cyclone. Dujuan then fluctuates between tropical-storm and typhoon classifications, with wind speed changing between 111 km/h and 130 km/h while pressure ranges from 980 mb to 971 mb.

Dujuan’s movement is initially slow and variable, including a stationary first reading and several westward phases. The storm then turns northeast and accelerates, reaching 48 km/h in the latest reading. After the peak wind of 130 km/h on September 21, wind speed decreases to 111 km/h and pressure rises from 970 mb to 975 mb. Those latest readings show weakening at the end of the observation history, without describing what happens afterward.

How to track Dujuan

Open the tropical storm tracks layer in RainViewer to follow Dujuan’s recorded position across the map. Each track point is coloured by the category recorded 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. Compare the latest point with earlier points to see the measured changes in position and classification.

For Dujuan, the latest points show a northeastward turn and increasing forward speed, followed by a change from typhoon to tropical storm classification. Check the newest position, wind speed and pressure against the previous reading rather than treating the track as a forecast. RainViewer updates radar every 5 minutes. Set an alert for your area in the RainViewer app on Google Play or the App Store. For official warnings, consult Japan’s national weather service or the weather service responsible for your location.

What the readings reveal about Dujuan’s western Pacific formation

The observation file does not record the atmospheric conditions that formed Dujuan. The first reading is on September 13, 2026, in the western Pacific, and the system remains over water throughout the available history. Tropical cyclones commonly form when thunderstorms organise over warm tropical water, but the file contains no measurements of water temperature, moisture, wind shear or the larger weather pattern. The precise reason Dujuan formed at that time and place is therefore not known.

The available data does not include a historical storm database or enough information to make a reliable comparison with earlier western Pacific storms. No past storm, year, peak category or outcome can be verified from these readings alone. Dujuan’s recorded history can be described precisely: it formed as a tropical depression, reached typhoon strength twice, peaked at 130 km/h, and was a tropical storm in the latest observation. Broader historical comparisons are not included rather than guessed.

Storm FAQ

Why did Dujuan change between typhoon and tropical storm?

The classification changed because the recorded sustained wind speed crossed the basin’s typhoon threshold. Dujuan was listed at 120 km/h or 130 km/h as a typhoon and at 111 km/h as a tropical storm.

What does Dujuan’s pressure number mean?

Central pressure is the air pressure near the centre of the storm, measured in millibars. Lower pressure often accompanies a more organised tropical cyclone, but the pressure reading alone does not describe conditions at any particular place.

Why are tropical cyclones given names?

Names distinguish one tropical cyclone from another when several systems may be monitored in the same basin or season. A name also gives forecasts and records a clear reference for the same storm over time.
