Notices & outages ...RADAR.WEATHER.GOV DATA OUTAGE...

NWS is reporting a problem affecting weather.gov, NCO and radar. Some data may be missing, delayed or slow until it is fixed.

The message says NWS is actively working the issue, so this is a live situation rather than a closed one.

Weather.gov is the public NWS website, NCO is NWS Central Operations, which runs the computing behind the forecast models and radar is the NEXRAD weather radar network.

For most people this is invisible — forecasts keep coming. It matters most to anyone pulling NWS data directly, and to forecasters who lean on the affected feed.
