FAA Data Outage
Notices & outages ...UPDATE - FAA DATA OUTAGE...
Good news: a problem affecting FAA, NCO, METAR and PIREP has been resolved. Service should be back to normal.
FAA is the Federal Aviation Administration, which exchanges aviation weather data with NWS, NCO is NWS Central Operations, which runs the computing behind the forecast models, METAR is routine hourly airport surface weather reports and PIREP is pilot reports of conditions aloft.
Balloon reports 12Z UPDATED RAOB RECAP...
Twice a day, NWS and partner agencies release weather balloons that carry a radiosonde — a small instrument package that radios back temperature, humidity, pressure and wind as it climbs. Those soundings are one of the main ingredients in a forecast model’s starting conditions. This section is the roll call of stations that had a problem for the 12Z run.
35 stations were flagged: 25 sent no usable sounding at all, 7 reported a numeric status code, 1 had a balloon burst early, 1 was missing part of the transmission, 1 had bad data removed by quality control. A handful of gaps is normal and is not by itself a sign of a forecast problem — the models are built to work with an incomplete picture.

| MZT 76458 | Colonia Juan Carrasco Mazatlan · Mexico | The balloon burst early. It stopped reporting at 593 mb, so this sounding only covers the lower part of the atmosphere — forecasters and models got no data above roughly 4.3 km (14,000 ft). The GFS run still got a usable report from this station. (593 mb ≈ 4.3 km (14,000 ft)) | Short to 593.0mb for NAM.. full report in for GFS |
| BDA 78016 | L F Wade Intl · Bermuda | The station reported, but part of the sounding transmission was missing — specifically TTBB, the "significant levels" section that carries the extra detail between the standard pressure levels. | Missing TTBB |
| MZT 76458 | Colonia Juan Carrasco Mazatlan · Mexico | Quality control removed part of this sounding before it reached the models: temp, moist 595 to 593 mb.. super-adiabatic lapse rate. The rest of the sounding was still used. | Purged temp, moist 595 to 593 mb.. super-adiabatic lapse rate. |
