Station and river observations

METAR/SPECI uses the existing AviationWeather.gov bulk cache over the lower 48 and its margin. NWPS retains only gauges in the existing action-stage-or-above observed list; forecast-only gauges can have no observation. Absence never establishes zero wind, low water, or safe conditions.

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: 3; target 24 hours, at most 96 reports per station. Recording began 2026-10-17 06:15:07.108Z; oldest available reading 2026-10-18 18:00:00 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.

Values use the decoded station report. Null means not reported, never zero. Gust is kept separate from sustained wind.
