The NWS enterprise NOAA Weather Wire Service (NWWS) is a combined Internet (Open Interface) and satellite (SBN/NOAAPORT Channel 201) dissemination platform for critical weather information, alerts and warnings to the public in text format.

NWS recommends using both the Internet and satellite interfaces to provide the highest product availability to the user.

The NWWS Open Interface (NWWS-OI) requires an NWS issued User_ID and password.  The satellite service (NWWS-PID201) does not.  PID201 can be received via a 1.8m satellite dish (2m+ is recommended to reduce side-band interference).

NWWS-OI requires an XMPP reader or commercial software to access the message text.  Information on configurations and software requirements is available on the NWWS webpage.


NOTE: NWWS-PID201 does not carry the complete offering of NWS products. PID201 only broadcasts NWWS directed text products as issued by the Weather Forecast Offices and National Centers. For a full distribution of NWS products use NWS FTP anonymous (over the Internet) or SBN/NOAAPORT Channels 101-108 (4m dish required).
