Replay uses retained source bytes. Recording begins with activation; missing history is not clear weather.

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.

Forecast comparison unavailable: these records have no matching forecast valid times. No interpolation or six-hour step is assumed.

Data coverage

JTWC has no NHC cone, NHC wind probabilities or NHC civil coastal warnings. Local national services remain the warning authorities.

Geographic context: Natural Earth boundaries and representative place labels. Radar coverage is limited offshore. Satellite pixels keep their source palette and actual observation time. Missing imagery is not clear weather.

No supported U.S. NWS monitoring area for this advisory. This does not mean no warnings worldwide.

Lightning activity — GOES GLM

Total lightning, including in-cloud activity. Not ground-strike locations or a safe-to-go-outside signal.

Each 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. Same-time corrections replaced in the publisher’s index cannot be selected unless still listed.

Monitoring geography and current changes

Area: None: JTWC’s forecast track passes within 300 nm of no U.S. territory with NWS zones, Warning 9
JTWC issues no cone and no coastal segments, so the area is the territories its track reaches.
