ⓘ About this map
The cone describes center uncertainty; impacts can extend outside it.

MaverickWX map · Data: NOAA/NHC · not an official graphic
Recorded weather · gaps are marked. Coverage begins with recording activation.
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.

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.

Advisory history
Return to latest advisoryThe issuance history could not be read. This is not an absence of previous advisories. 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.
