  • There is a single XMPP chatroom that has a single user inside the room that is able to talk.  This bot user emits a <message> stanza that contains a special payload that has the raw text included.  Here is an example message stanza:
     
  • So if you are in the chatroom with a client that does not process this special <x> payload, you won’t see all the raw text included in the stanza.  The attributes on the <x> stanza are as follows:
     
  • The id attribute on the <x> stanza is meant to help clients know if they are missing any products as they parse the stream.  The id contains two values loaded up into one and they are separated by a period. The first number is the UNIX process ID on the system running the ingest process.  The second number is a simple incremented sequence number for the product.
     
  • When users join the chatroom, they are given a 60 message history.   These messages may not contain the <x> payload in the situation where the server is restarted.

  Mission

  The mission of the National Weather Service is to provide weather, water, and climate data, forecasts, warnings and Impact-based Decision Support Services (IDSS) for the protection of life and property and enhancement of the national economy. NWWS supports this mission with timely dissemination of weather information, alerts, and warnings for use by the public, re-broadcast by the media, and integration into both private and commercial software applications.

   

• History
   

  History
  YEAR	HISTORY OF THE NOAA WEATHER WIRE SERVICE
  1849	Weather alerts and information are distributed via telegraph wire.
  1890	Weather services transferred from the Signal Service to the newly formed U.S. Weather Bureau under the Department of Agriculture.
  1928	Teletype replaces telegraph for weather distribution.
  1940	U.S. Weather Bureau transferred to Department of Commerce.
  1970	U.S. Weather Bureau renamed National Weather Service (NWS).
  1999	NWS develops and implements leased NOAA Weather Wire Service (NWWS) using satellite distribution to States and television and radio broadcasters.
  2003	NWWS implements Internet access for all user subscriptions (both public and private).
  2015	NWS enterprise architecture NWWS replaces the leased legacy NWWS.

   

• NWWS Description
   

  NWWS DESCRIPTION

  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 ingest 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).       NWWS is one method used by television and radio broadcasters to activate the local Emergency Alert System (EAS). NOAA Weather Radio All Hazards (NWR) is the other.

• Hours of Operation / Availability
   

  NWWS operation: 24 hours / day* * up to four times a month planned NWS server-farm transitions have a 10-90 minute synchronization outage to allow for security patches, software updates, and other planned system maintenance. Time to recover after a server transition can be reduced with proper system set-up, DNS configuration, and access through firewalls. Users should restart their system after each transition to ensure proper NWWS-OI connectivity. If there are reconnection issues the Senior Duty Meteorologist is available 24 hours / day. Transition information will be posted under Notices; next to the operational status on the upper right of this webpage. NWWS Program Office hours: M-F 8am-5pm ET.

• Some NWWS application software can be set up for “tone alert” notification(s), and text messages can be sent to braille printers.
   
• Critical alerts and warnings are the same that are sent over local Emergency Alert Systems (EAS) and sent to Wireless Emergency Alert (WEA) capable telephones.

• During monthly transitions, some users lose connectivity with the NWWS-OI due to security firewall and DNS settings until the next transition.  Be sure to allow both IP addresses through security firewall(s).
   
• During monthly transitions, users that lose connectivity should reset the NWWS-OI software application or restart their computer system to correct the problem.
   

• There is currently an update issue where users may experience random disconnects or account authentication errors.  Please be patient, these issues eventually self-correct.  Some systems may time-out attempting to connect; if this happens wait 30-minutes and then attempt to connect to the NWWS-OI.

• Please ensure the IP addresses are properly configured within your system and for your firewall access; 
  • NWWS PRIMARY IP address: 140.90.59.197
     
  • NWWS BACKUP IP address: 140.90.113.240
     
  • NWWS-OI can be served by either of the two IP addresses.
     
  • Users should make sure that their firewalls are open for both IP addresses, but should allow their DNS systems to determine which IP is the active server.
• Reset system
   
• For password issues and resets contact NWWS.Help@noaa.gov.
