NWWS text products can be received via satellite over SBN/NOAAPORT Channels 101-105 (PID 101-105) and Channel 201 (PID 201).
NWWS Open Interface (NWWS-OI) via the Internet is the fastest means of receiving alerts and warnings for EAS activation. There are other methods and formats for receiving NWWS text products over the Internet as well (see DISSEMINATION) just not as fast. NWWS-OI access can be requested using the tab below.
If you need a software client to read the NWWS-OI XMPP format, use the EUC tab below to request URL for the current EUC program. The EUC is capable of receiving and de-duplicating both PID 201 and NWWS-OI product ingests.

Here are the top 6-reasons there may be an authentication failure;
- User_id or Password is incorrect; these are case sensitive.
- Firewall(s) have not been adjusted.
- Port assignment is not "5223"
- Router was not configured properly
- Not connecting to nwws-oi.weather.gov
- Applications accessing resources on weather.gov need to provide a User-Agent header in any HTTP request. Requests without a user agent are automatically blocked. This policy is due to a small number of clients utilizing resources far in excess of what most would consider reasonable. We recommend providing a user agent string in the following format:
This will both uniquely identify your application and allow us to contact you and work with you if we observe abnormal application behavior that may result in a block.
Software SyntaxModification to ID user if needed;
WeatherSoftware/v2.0 (http://www.Weather Company XYZ.com/; POC FirstName.POCLastname@WeatherCompanyXYZ.com; UserID Tracking # or e-mail)
Individual Developers (variation)
MyJava/v7.1 (http://www.CompanyApp.com/ , personal URL or blank; Applicable Company POC@company.com or personal e-mail)
Again, this will both uniquely identify the application used and allow us to contact you and work with you if we observe abnormal application behavior that may result in a block.
If after checking the above you still have an issue, use the NWWS Help e-mail (firstname.lastname@example.org) to describe the error code you are receiving (or problem) and we will try to assist.
Remember: Only one (1) program on one (1) computer can use the assigned user_id and password to log into the NWWS Open Interface (OI). Violating this will crash your system(s).
End User Client (EUC) Issues
1.If using the NWS EUC and your system is running slower than usual or appears frozen multiple copies of the EUC may be open. Close all EUC windows and restart.
2.Wrong bit rate (32 or 64) software program is used (NWWS End User Client specific).
3.Improvements and updates to the EUC may occur from time to time but are not guaranteed. Update notice will be e-mailed to NWWS users.

- Latest Service Change Notice (SCN)
- NWWS-OI and SBN/NOAAPORT Channel 201 will not have the CAP v1.2 format at this time. NWWS requires native CAP v1.2 generation from the Weather Forecast Office (WFO) Advanced Weather Interactive Processing System (AWIPS) for NWS Enterprise wide dissemination.
- SBN/NOAAPORT Channels 101-105 (which are all NWS products including alerts and warnings) has the CAP v1.2 format as described in the SCN.
