What's happening now
Koguma ended as a tropical storm over open water with nothing nearby, at 38.3°N, 157.2°E and moving northeast at 39 km/h in its final reading. The final observation, at 18:00 UTC on October 13, recorded sustained winds of 93 km/h, gusts of 107 km/h and a central pressure of 988 mb. Koguma had weakened from its recorded peak of 222 km/h, reached on October 10 at 12:00 UTC; another 222 km/h reading came six hours later. The lowest listed pressure was 941 mb at 18:00 UTC on October 10. Wind speeds declined in the final readings as the storm transitioned from typhoon to tropical storm at 12:00 UTC on October 13.

How Koguma developed
October 5 — Recorded as a tropical depression
At 00:00 UTC on October 5, Koguma was recorded as a tropical depression 141 km off the Marshall Islands. The reading showed 56 km/h wind, 64 km/h gusts and 1,002 mb pressure. The system was moving toward 30° at 9 km/h.
October 5 — Strengthens into a tropical storm
At 06:00 UTC on October 5, Koguma was recorded as a tropical storm with 65 km/h winds, 75 km/h gusts and a pressure of 1,000 mb. At 00:00 UTC, Koguma was a tropical depression with 56 km/h winds, 64 km/h gusts and a pressure of 1,002 mb.
October 8 — Strengthens into a typhoon
At 12:00 UTC on October 8, Koguma's sustained winds reached 120 km/h, with gusts of 138 km/h and pressure of 985 mb. The reading classifies Koguma as a typhoon, following a tropical-storm reading 6 hours earlier with 111 km/h winds and 989 mb pressure.
October 13 — Weakens to a tropical storm.
At 06:00 UTC, Koguma was still a typhoon with winds of 130 km/h and pressure of 978 mb. By 12:00 UTC, winds had fallen to 111 km/h and pressure had risen to 985 mb, and the reading classified Koguma as a tropical storm. The readings mark its transition from typhoon to tropical storm.
How Koguma is behaving
The available observation shows Koguma at tropical-depression strength, with 56 km/h maximum sustained wind and 64 km/h gusts. The 1,002 mb central pressure is one measurement of the air pressure at the storm’s centre. Because the file contains only one reading, it cannot show a pressure trend or establish whether the circulation is becoming more organised or coming apart. The same limitation applies to movement: a bearing of 30° and speed of 9 km/h describe one moment, not how steadily the system has travelled.
No observation sequence is available for comparing wind, pressure or direction over time. The current reading therefore supports a precise snapshot but not a diagnosis of strengthening, weakening, acceleration or a turn. The storm’s strongest recorded wind is also 56 km/h, matching the latest reading, so the available record does not show a higher measured intensity.
How to track Koguma
Turn on the tropical storm tracks layer in RainViewer to view the available position for Koguma. Track points use 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. Koguma’s recorded point is cyan because the reading classifies it as a tropical depression.
With one reading on file, there is no observed sequence yet for comparing Koguma’s direction or speed. Use the latest point to check its recorded distance from the Marshall Islands and its 30° bearing. Open the RainViewer app on Google Play or the App Store to follow the storm track as new observations become available.
Storm FAQ
What does tropical depression mean for Koguma?
A tropical depression is the tropical-cyclone classification shown for Koguma in the available reading. The reading records 56 km/h maximum sustained wind, and the track point uses the tropical-depression category.
What is the difference between Koguma’s wind and its gusts?
The 56 km/h figure is the recorded maximum sustained wind, while 64 km/h is the recorded gust speed. A gust is a brief increase in wind speed rather than the sustained-wind measurement.
Why is this storm called Koguma instead of having a personal name?
The available observation file identifies the system as Koguma. The file does not state whether or when a different storm name will be assigned.
Why are tropical cyclones given names?
Names help distinguish one tropical cyclone from another when several systems exist in the same basin or season. A name also gives weather services and the public a clear label for referring to one system.
