Typhoon Cempaka is over open water at 30.2°N, 154.1°E, moving northeast at 57 km/h. The latest reading, at 12:00 UTC on 11 November, records sustained winds of 120 km/h, gusts of 138 km/h and a central pressure of 983 mb. Cempaka remains a typhoon in the western Pacific basin. The storm has weakened from its recorded peak wind speed of 176 km/h on 9 November, while its pressure has risen from a low of 963 mb to 983 mb. The latest wind reading is unchanged from 06:00 UTC; movement speed has increased from 48 km/h to 57 km/h. The latest reading names no nearby place or body of water. RainViewer does not provide official warnings; check your national weather service for official warning information.
No active watches or warnings.
November 3 — First reading records a tropical depression.
The first reading in the record places THIRTYONE over open water at 16.9°N, 165.4°E, with winds of 28 km/h and gusts of 32 km/h. The reading records no movement. This marks the start of the available observation history, not necessarily the storm’s formation.
November 4 — Winds rise to 37 km/h.
At 06:00 UTC, the recorded wind speed rises from 28 km/h to 37 km/h, with gusts increasing to 43 km/h. Later readings that day keep the same wind and gust speeds. The storm’s recorded movement is generally westward, at speeds between 24 km/h and 34 km/h.
November 6 — Winds reach 46 km/h as the heading turns north-west.
At 00:00 UTC, the wind speed rises to 46 km/h and gusts reach 53 km/h. The recorded heading changes from 287° in the previous reading to 306°, then 308° at 06:00 UTC. The latest reading keeps the wind and gust speeds unchanged and records movement at 33 km/h.
7 November — Strengthens to a tropical storm.
At 00:00 UTC on 7 November, THIRTYONE's classification changes from tropical depression to tropical storm. Sustained winds rise from 56 km/h at the previous reading to 65 km/h, while gusts increase from 64 km/h to 75 km/h. Central pressure falls from 1,005 mb to 1,004 mb. The 65 km/h sustained wind is the strongest value in the record.
8 November — Strengthens into a typhoon.
At 00:00 UTC on 8 November, Cempaka's classification changes from tropical storm to typhoon. Sustained winds rise from 111 km/h six hours earlier to 120 km/h, with gusts increasing from 128 km/h to 138 km/h. Pressure remains 992 mb, and the centre is in the Philippine Sea at 21.4°N, 138.7°E.
The readings show a gradual increase in sustained wind: 28 km/h at the first observation, 37 km/h by November 4, then 46 km/h on November 6. The wind held at 37 km/h across several readings before that increase, and it has remained at 46 km/h in the latest 2 readings. Gusts followed the same pattern, reaching 53 km/h. The latest central pressure is 1,007 millibars, but only that one pressure value is provided, so the record does not establish a pressure trend. Recorded movement increased from no movement in the first reading to speeds mostly between 23 km/h and 37 km/h. Recent headings shifted from westward to north-westward.
Turn on the tropical storm tracks layer in RainViewer to follow THIRTYONE’s recorded positions. Each track point shows the storm’s category at that moment: tropical depression in cyan, tropical storm in blue, category 1 in yellow, category 2 in amber, category 3 in orange, category 4 in red, and category 5 in dark red. THIRTYONE’s readings identify it as a tropical depression, so look for cyan points along its track.
Compare the latest position and movement with earlier points to see how THIRTYONE’s path has changed. The readings show a generally westward track followed by a shift towards the north-west, while its wind speed rose from 28 km/h to 46 km/h. These observations describe the recorded track and intensity, not what will happen next. Download RainViewer from Google Play or the App Store to follow the storm’s track.
Names help people distinguish one tropical cyclone from another in forecasts and public communication. This storm’s record uses the designation THIRTYONE.
Millibars measure air pressure; the storm’s latest reading is 1,007 millibars. One reading alone does not show whether pressure is rising or falling.
Wind speed is the sustained wind value in a reading, while a gust is a brief higher burst of wind. THIRTYONE’s latest reading gives 46 km/h winds and 53 km/h gusts.
