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.

Stage in this gauge’s units, not a regional flood depth. Tide/lake gauges remain water levels; datum is not supplied by this feed. Historical observations and the latest forecast keep separate times.

Retained observations: 3; target 24 hours, at most 96 reports per station. Recording began 2026-10-17 06:15:05.234Z; oldest available reading 2026-10-18 07:00:00 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.

Only observed gauge records enter this history. Forecast maxima and forecast hydrograph points never become observations. A missing datum or unsupported flow value remains unknown.
