Notices & outages

This is a heads-up about planned work on IRIS and NCO. Brief interruptions are expected during the work window rather than something having gone wrong. The notice expects an interruption of up to 30 minutes.

IRIS is an NCO data handling system 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.
