NOAA Weather Wire Service

The National Weather Service (NWS) enterprise National Oceanic and Atmospheric Administration (NOAA) Weather Wire Service (NWWS) provides television and radio broadcasters, emergency managers, commercial / private alerting services, and the general public the fastest receipt of current weather information, alerts and warnings sent in text format from the local NWS Weather Forecast Offices and National Centers.

NWWS has been designed to use both an Internet (NWWS-Open Interface) and a Satellite product source (SBN/NOAAPORT Channel 201).  Use of both is highly recommended to achieve a >98% product availability rating.  The NWWS Open Interface will experience planned and unplanned outages up to three times per month; with planned outages lasting on average between 10 minutes to less than 4-hours.  See the CONFIGURATION tab for setup requirements.


NWS has resumed NWWS-OI server transitions. The next transition to PRIMARY date and time is to be determined.

NWS has resumed NWWS-OI server transitions. The next transition to PRIMARY date and time is to be determined. An outage once the transition begins may last as long as 90 minutes. The timeframe for a transition may be later, extended or cancelled depending on NWS operational requirements and critical weather.

If your system is off-line or having trouble reconnecting after an outage, a system reset or restart should clear up the problem. If not, e-mail

Please note that NOTICES for planned outages will be posted when known. Thank you for your understanding.
