Krovanh ended as a tropical depression over Japan, moving north-east at 20 km/h in its final reading. The final reading on 9 September recorded 46 km/h winds, gusts of 53 km/h, and a central pressure of 1,003 mb. Krovanh had weakened from 56 km/h winds in the previous readings, while pressure had risen from 996 mb. The storm's strongest recorded intensity was tropical-storm strength, with 83 km/h winds and 982 mb pressure on 4 September over the East China Sea, 185 km off Japan. Krovanh spent most of its recorded life over the Philippine Sea, with several readings placing the centre off Japan before the final reading placed it over Japan. The feed ended after the 9 September, 06:00 UTC observation, so RainViewer has no later position or intensity reading.
No active watches or warnings.
1 September — First reading as a tropical storm
Krovanh’s oldest reading records a tropical storm over the Philippine Sea at 22.5°N, 131.5°E. Sustained winds measured 65 km/h, gusts reached 75 km/h and pressure measured 995 mb. The storm was stationary at that observation, with movement recorded as 0° at 0 km/h.
1 September — Begins moving east
By 12:00 UTC, Krovanh remained a tropical storm with 65 km/h winds and 993 mb pressure. The storm moved east at 7 km/h, recorded as 100°. Six hours later, Krovanh was still at tropical-storm strength and moving east at 11 km/h, while pressure rose slightly to 994 mb.
2 September — Weakens to a tropical depression
At 00:00 UTC on 2 September, Krovanh’s classification changed to tropical depression. Sustained winds fell to 56 km/h and gusts to 64 km/h, while pressure remained 994 mb. The storm moved at 6 km/h in the 80° direction, east-northeast by the compass bearing.
2 September — Regains tropical-storm strength
At 06:00 UTC, Krovanh returned to tropical-storm strength with 65 km/h winds and 75 km/h gusts. Pressure stayed at 994 mb. The storm had turned towards the north, moving at 7 km/h on a 345° bearing, compared with the eastward motion in the previous readings.
2 September — Turns north-west and accelerates
The latest reading records Krovanh as a tropical storm with 65 km/h winds, 75 km/h gusts and 993 mb pressure. The storm is moving north-west on a 325° bearing at 15 km/h. The latest position is 23.9°N, 131.7°E, over the Philippine Sea.
5 September — Weakens to a tropical depression
At 12:00 UTC on 5 September, Krovanh weakened from a tropical storm to a tropical depression. Maximum sustained winds fell from 65 km/h to 56 km/h, gusts fell from 75 km/h to 64 km/h, and pressure rose from 988 mb to 993 mb. The centre was 82 km off Japan.
Krovanh’s six readings show a narrow pressure range of 993–995 mb. Pressure fell from 995 mb to 993 mb during the first eastward movement, rose to 994 mb as the storm weakened to a tropical depression, then returned to 993 mb in the latest reading. Wind speed followed a similarly uneven pattern: 65 km/h at tropical-storm strength, 56 km/h during the depression stage, then 65 km/h again. The record supports a brief weakening followed by renewed tropical-storm classification, not a sustained strengthening trend.
Krovanh’s movement changed substantially across the record. The first reading showed no movement, followed by eastward travel at 7–11 km/h. The storm then moved at 6 km/h on an 80° bearing, turned to 345° at 7 km/h, and reached 15 km/h on a 325° bearing in the latest observation. A bearing is the direction of travel measured clockwise from north. The track therefore shows a turn from eastward motion towards north-westward motion, with speed increasing in the final interval.
Turn on the tropical storm tracks layer in RainViewer to follow Krovanh’s six recorded positions over the Philippine Sea. Each track point is coloured by Krovanh’s classification at that moment: cyan for tropical depression, blue for tropical storm, yellow for Category 1, amber for Category 2, orange for Category 3, red for Category 4 and dark red for Category 5. Krovanh’s points include the brief tropical-depression stage between tropical-storm readings.
Compare the spacing and direction of Krovanh’s points to see how its movement changed from stationary, to eastward, and then towards north-westward motion. The latest reading shows the highest recorded movement speed in this file, 15 km/h, along with tropical-storm winds of 65 km/h. Open the RainViewer app on Google Play or the App Store to follow the recorded track as new observations become available.
The supplied record places Krovanh in the 2026 western Pacific season and identifies the Philippine Sea as the water in every observation. The file begins on 1 September 2026, when Krovanh is already classified as a tropical storm, so the readings do not establish when or where the system formed. The data also do not provide the environmental conditions around formation, such as ocean temperature, wind shear or moisture.
The available information does not include a catalogue of earlier western Pacific storms, their peak categories or their outcomes. No reliable comparison with a named past storm can therefore be made from this record alone. Krovanh’s documented history here is limited to six observations: tropical-storm strength, a brief tropical-depression reading, a return to tropical-storm strength and a turn towards north-westward movement.
Krovanh’s classification changed because its recorded sustained wind speed fell from 65 km/h to 56 km/h, then returned to 65 km/h. A tropical depression has lower sustained winds than a tropical storm, so the classification can change when the measured wind crosses that threshold.
Central pressure is the air pressure near the storm’s centre, measured in millibars. Lower pressure can occur in a more organised tropical cyclone, but pressure alone does not describe the storm’s full structure or its effects.
Meteorological agencies name tropical cyclones so separate systems can be identified clearly in forecasts, observations and records. Names reduce confusion when several storms exist in the same basin or season.
