Notices & outages ...METARS MISSING/DELAYED IN AWIPS...

NWS is reporting a problem affecting AWIPS and 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.

AWIPS is the workstation software forecasters use to build and issue products and 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.
