Live sources keep independent clocks.
Replay coverage and interpretation
Rolling target: 24 hours; cells: six hours. Radar: NOAA MRMS national overview, 8-minute tolerance. Satellite: original GOES GeoColor day/night picture, hourly sampling, 75-minute tolerance. No interpolation or latest-image fallback. Warning and source checks retain their own clocks. “Recorded by” is collector acquisition evidence, not exact browser publication history.
Current GLM density, velocity and specialist layers are hidden during replay. Snow uses retained footprint metadata with unverified pixel time. Forecast uses one pinned issuance/run and exact valid time.
No observed replay frame displayed.

Analysis
Area, source times and interpretation
Current cached context, independently dated. Regional products keep their published footprint; they are not clipped or attributed to one storm. This section remains separate from the historical replay cursor and official cyclone forecast. Use Forecast to pin a retained model package.
Soundings: what weather balloons measured
A balloon launched about an hour before the time named, measuring as it rose and drifted with the wind: the atmosphere above one place, at one time. Model soundings, which are forecasts, are not shown here.

Impacts
No supported U.S. monitoring areaCurrent warnings in the monitoring area
None: JTWC’s forecast track passes within 300 nm of no U.S. territory with NWS zones, Warning 26. Current geographical context; these alerts are not attributed to the cyclone.
No U.S. area
No U.S. territory is in this storm’s area: JTWC’s track passes within 300 nm of none. Its own panels are shown, and no NWS alert is listed.

Advisory history
Return to latest advisoryEach entry selects one immutable snapshot. Intermediate, special and corrected records are separate identities where retained. Current NWS context is labelled separately. Historical impact manifests are not retained by this index; newer impacts are never attached to an earlier advisory.
