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.

Due to a configuration issue, NWWS-Open Interface accounts can only be issued when the operational server is PRIMARY.
There may be a delay of 30-60 days for accounts to be resolved once requested. Thank you for your patience.

The NWWS-OI was transitioned to the Primary Server on 5/20/2022.
