ⓘ About this map

Outlines: NOAA/NWS · Radar cells: IEM/NEXRAD. Outlines are warned areas, not storm paths.

Interactive imagery loads separately. Missing radar does not remove warnings or imply clear weather.

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.

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.

Station and river observations (160)

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.
