Tuesday rebuilt from what the files still hold

What it tries: A past day cannot be read from a live feed, because the feed drops what has expired. This is the day in bands opened on Tuesday and built only from what we kept: IPMA's warning messages (each marked "in the feed" or, dotted, "rebuilt: left the feed" with the time it left), the stations' kept hours and the airport's reports. Shading is on one scale per unit, so a km/h cell means the same in every band.

What it shows badly: Our record starts at our first read of the warning messages (10 November, 23:51 UTC), so a warning replaced and dropped before then is not shown and the day may look calmer than it was warned to be; no hourly forecast for Tuesday was kept; and one scale per unit makes small values nearly white, which hides differences on a quiet day.

An experiment from the Labs, made at incident.weather@'s ask, for the Weather face to lift if it holds up. It reads only this site's published JSON: weather/cap.json, weather/warnings.json, weather/lisbon-rain.json, weather/airport.json, weather/forecast.json, weather/analysis.json, decisions/graph.json. Click any mark for its item, its source and the time it was read. Not a warning service: for the warning itself, IPMA and ANEPC.
