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.
Source-rendered snow depth and snow water equivalent for the lower 48. History changes this snow picture only; warnings and radar keep their own clocks.
No NOHRSC picture displayed on the interactive map.

NOAA/NWS/NOHRSC’s original picture and legend. No station or address value is inferred.
NOHRSC footprint times are metadata; pixel analysis time is not independently verified. Snow-depth pixels have previously differed from the footprint time. This is modeled/assimilated snow analysis, not a measurement at a place. Unshaded and no-data areas do not establish zero snow.
Collector checked ; feed generated . Zero cells does not establish coverage or clear weather. Observations from different radars are not merged.
Station and river observations (26)
Surface source current; observed water-level source current. Each reading keeps its own time. Map markers show at most 500 stations and 500 gauges; the complete source directory is paginated.
Circle: surface station; square: water-level gauge. Filled: current reading and source; hollow: stale, unconfirmed or missing observation. Marker color is not a hazard category. Enable “Stations and gauges” in Layers to inspect them on the map.
Station observations, not an address forecast or cyclone maximum wind. Maintenance-flagged, old and implausible reports are excluded by the existing parser; this is not independent NWS quality control.
Retained observations: 68; target 24 hours, at most 96 reports per station. Recording began 2026-10-17 06:15:07.108Z; oldest available reading 2026-10-17 05:56:00 UTC.

Capture times, quality and provenance
Each report keeps its observation time, first capture of this version, and the SHA-256 of the source bulk body. Corrections at the same observation time replace that point and are marked; unrelated bulk-file changes do not freshen a report.

Source-message history is not recorded imagery replay. Recorded radar/satellite imagery is not available in this view.
Auto-updating checks this site’s cache every minute; each source keeps its own clock.
Coastal observations
Scheduled public-station observations
Water levels are relative to the named datum, not flood depth above ground. Observations keep their own report times.
Coverage and interpretation
Observed water level is relative to the named vertical datum, not flood depth above ground. Observed minus predicted tide is a matched-time residual, not a universal storm-surge or inundation forecast. Buoy wind is not a cyclone maximum; significant wave height is not coastal flood depth. Missing readings are not zero.
Only operator-configured public stations are collected. Coastal context includes stations inside the named monitoring area or within 100 nautical miles of a vertex of its published outline, so offshore buoys can be included; this is a proximity rule, not an impact footprint. Cyclone-only context is within 600 nautical miles of the selected advisory center. Shown center distances are not impact radii. Station-file history without a reported position is not assigned a historical location.
