NOTE: Not all alerts and warnings (or weather products) may be available over the NWWS. In most cases, it is up to the issuing Weather Forecast Office (WFO) or Center to determine if dissemination via NWWS is appropriate.

Prior to 2009, the National Weather Service (NWS) has maintained an NWWS Excluded Product List. Until 2015, this list was implemented as a filter by the NWWS contractor before satellite or Internet dissemination to NWWS users. In 2015, NWS developed an enterprise NWWS to replace the leased service, and the Excluded Product List could not be filtered from a central NWS location. Weather Forecast Offices (WFOs) were requested to update the AWIPS NWWS Exclude File on the respective AWIPS. As WFOs update exclude files, these products will appear to go missing. These products can be found on other dissemination platforms or media (Click here FTP/WEBSITE PRODUCTS LINKS for where to locate EMWIN or other NWS products.).
