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

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

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

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.

REFS / HRRR: feeds current

REFS: Feed current; checked .

HRRR: Feed current; checked .

Checked means retrieved, not newly issued. Each graphic retains its issue, observation, initialization or valid time. Site publishing status is separate.

Forecast REFS run , hour +6, valid . Chance of a rotating updraft nearby (2–5 km updraft helicity over 75 m²/s² in the hour). Data: NOAA/NCEP.

Rotating storms

How many of the ensemble’s members grow a storm with a strongly rotating updraft near each point in the hour: the model’s sign of a supercell, which can bring tornadoes, large hail and damaging wind.

A forecast’s own uncertainty, not a forecast of coverage: REFS is a set of runs of NCEP’s RRFS model, each started a little differently, and the share is how many of them put the event near a point. 30% is three runs in ten. It is guidance forecasters weigh, not SPC’s outlook and not a warning.

Share of members

  • 10–30%
  • 30–50%
  • 50–70%
  • 70–90%
  • 90% or more
  • under 10%: not drawn

Highest anywhere in the hour: 79.5% of members.

Pre-operational: NCEP’s parallel REFS, which it plans to make operational on 3 November 2026 (Service Change Notice 26-48). Until then it may be late, missing or changed without notice.

Retention & comparison limits

Only rolling current frames and limited previous copies are retained. Complete historical runs are not archived, so two-run comparison is unavailable. Only the published forecast hours are stepped; gaps are explicit. Rainfall uses WPC’s existing forecast, not an unprovided model rainfall field.

Current warnings in the monitoring area

None: no U.S. state or territory is under NHC’s coastal watches or warnings or inside the cone, Advisory 26. Current geographical context; these alerts are not attributed to the cyclone.

No U.S. area

No U.S. state or territory is under NHC’s coastal watches or warnings or inside the cone. The storm’s own panels are shown, and no NWS alert is listed.

Advisory history

Return to latest advisory

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.
