JTWC forecast for Tropical Depression Atsani, Warning; rendered by MaverickWX

Published advisory track · Warning

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

JTWC does not publish an NHC cone.

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.

Open the complete replay reader (works without scripting or WebGL)

Choose Forecast for a pinned issuance and valid time.

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

SPC’s skew-T diagram and hodograph of the sounding at Chihuahua, Mexico (76225), 12Z. Its levels are in the table below. — Observed Sounding at Chihuahua, Mexico (76225), for 12:00Z (9 h 34 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.

Advisory comparison

Comparison unavailable: no different, earlier retained advisory was selected or published.

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.

Advisory history and records

Advisory history

Return to latest advisory

The 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.

No verifiable retained snapshots are 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
JTWC issues no cone and no coastal segments, so the area is the territories its track reaches.
