Notices & outages ...NWWS OUTAGE...

NWS is reporting a problem affecting NCO. 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.

NCO is NWS Central Operations, which runs the computing behind the forecast models.

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.
