Spot And IRIS/iNWS Failovers Scheduled For Today
Notices & outages ...SPOT AND IRIS/iNWS FAILOVERS SCHEDULED FOR TODAY...
This is a heads-up about planned work on IRIS, NCO and SPOT. Brief interruptions are expected during the work window rather than something having gone wrong. The notice expects an interruption of up to 15 minutes.
IRIS is an NCO data handling system, NCO is NWS Central Operations, which runs the computing behind the forecast models and SPOT is the application forecasters use to issue spot forecasts — site-specific forecasts requested for wildfires and other incidents.
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.
