Champi, 2630 and TC2636: match the right storm
JMA’s 21 October title identifies Champi as 2630, with data identifier TC2636. The tracker verifies the name and both identifiers before showing current values. Koguma 2629 / TC2634 is a different record. Keep the year and agency with a storm name when comparing search results or shared maps.
21 October analysis: where was Champi?
The product issued at 00:45 UTC used an analysis valid at 00:00 UTC: center 18.1°N, 130.2°E. The publication and analysis times answer different questions. The live panel may receive a later product; these article figures remain tied to this dated example. The selected JMA files do not provide wind or pressure, so this site leaves those values unavailable.
What did the next forecast points show?
The October 21 product forecast 19.3°N, 128.1°E for 12:00 UTC that day and 20.3°N, 126.4°E for 00:00 UTC on October 22. Its 72-hour point was 25.5°N, 122.0°E at 00:00 UTC on October 24. These are future center positions in a dated forecast, not observations or guarantees. They do not establish a Japan or Philippines landfall, an affected town, or a local warning. Open the current JMA map for revised points and their valid times.
How to read the JMA probability circle
JMA’s probability circle describes uncertainty in the future storm center: its stated center-position probability is 70%. It is not the typhoon’s physical size or the full area of hazardous weather. Compare the center, circle, separate wind areas and valid time together.
Japan and Philippines: which warnings should I use?
For a Japanese location, use JMA’s local warning and forecast products. For a Philippine location, consult PAGASA’s current products and check whether the system is within their relevant coverage. A regional forecast point alone cannot determine local impacts or transport operations. The country guides below link the responsible agencies.
Automatic checks, source outages and sharing
This page checks JMA every five minutes while open. If Champi is no longer listed, identifiers do not match or a request fails, the panel clears current values and retains the official links. Share the year, source agency and issue time with the page. Sharing does not subscribe anyone to emergency alerts.
