CPHC forecast for Tropical Storm Pena, Advisory 10; rendered by MaverickWX

Published advisory track · Advisory 10

Observed imagery loads separately from the advisory. The base map is not observed satellite imagery.

ⓘ About this map

The cone describes center uncertainty; impacts can extend outside it.

Basemap

MaverickWX map · Data: NOAA/NHC · not an official graphic

Change time or forecast product

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.

Soundings: what weather balloons measured

SPC’s skew-T diagram and hodograph of the sounding at White Lake, MI (DTX), 00Z. Its levels are in the table below. — Observed Sounding at White Lake, MI (DTX), for 00:00Z (3 h 21 min ago). SPC’s graphic; the values in its panels (CAPE, shear, the indices) are SPC’s computations from these levels. Data: NOAA/SPC.

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.

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.

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

None: no U.S. state or territory is under NHC’s coastal watches or warnings or inside the cone, Advisory 10. Current geographical context; these alerts are not attributed to the cyclone.

Data coverage

NHC/CPHC track, coastal alerts, probabilities and wind timing retain separate coverage and issuance.

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.
