Storm System Continues To Impact Southern California, Severe Weather Threatens The Southern And Eastern U.S.

A storm system will deliver heavy mountain snow and rainfall to southern California and the Desert Southwest through late week. The heavy rainfall may pose a flash flood risk, especially to burn scar locations. Severe thunderstorms capable of damaging winds, hail, and tornadoes will be possible from the Southern Plains to the Mississippi Valley, Mid South, and Mid Atlantic through Wednesday. Read More >

NOAA Weather Wire Service (NWWS)

 

SERVICE STATUS EVENT
NWWS - Satellite PID 201 OPERATIONAL  
NWWS - Open Interface (OI) OPERATIONAL Primary

Next planned transition will be April 14-16.

 

NWWS will be transitioning every month (second or third week) for security and software upgrades. This timeline may be delayed or extended based on holidays, declared Critical Weather Days (https://www.nco.ncep.noaa.gov/pmb/cwd/), and emergency patches.  

Planned dates: April 14-16    May 12-13    June 9-11    July 14-16    August 11-13

 

NWWS services as a status will remain “operational” (GREEN) until a planned or unplanned “outage” occurs (RED). There is a seamless service transition between the primary and backup systems with a 30-90 minute delay while files and systems re-sync .  E-notification will be provided when a service transition period is planned so users can maintain their respective system interfaces/connections over these temporary breaks in service. Please ensure your system firewalls allow both NWWS IP addresses listed under CONFIGURATION.
 

PROBLEM:  If you did not completely exit the XMPP program before shutting down, a “phantom” account will continue to exist.  This “phantom” account will prevent you logging into the NWWS-OI. 

Do not ask for account reset.

RECOMMENDED SOLUTION: Empty the cache and then log back in using the assigned user_ID and password.

  • If you experience outage, product loss, or login issue that cannot be resolved using the information under FAQ, please notify SDM@noaa.gov and cc NWWS.Issue@noaa.gov.

The mission of the NWS Dissemination Systems Branch is to disseminate weather information, alerts, and warnings to NWS partners, federal, state, and local emergency managers, and the public as quickly and accurately as possible.

The NWS Enterprise NWWS was designed to meet this mission.

NWWS (using both Internet Open Interface and SBN/NOAAPORT Channel 201 in concert) provides the highest product availability to the user.

NWWS is one method used by radio and television broadcasters to activate the local Emergency Alert System (EAS).
 

The National Weather Service(NWS) Enterprise NOAA Weather Wire Service (NWWS) developed in 2014 consists of several NWS Enterprise systems (AWIPS, NCF, NCO/IDP, NIDS and SBN/NOAAPORT). See NWWS Poster

The Enterprise NWWS was declared operational July 1, 2015.


NWWS provides text formatted messages via both satellite (SBN/NOAAPORT Channel 201) and the Internet (Open Interface).
  • Receiving both Internet and satellite product streams allows the recipient to achieve a 98% product availability.
  • SBN/NOAAPORT Channel 201 (aka PID201) are NWWS - only alerts, warnings and weather information in WMO Standard message format
  • NWWS-Open Interface (NWWS-OI) are NWWS-only alerts, warnings and weather information in XML/XMPP format and require additional information for access.

NWWS-OI access:
  • NWS issued user_ID and password. (see specific tab for each)
  • XMPP Chatroom interface/XMPP Reader (Java, Pidgin, etc.) – commercial application or user developed.

NOTE: No user_ID or password required for SBN/NOAAPORT satellite access; though the 1.2m (or larger) dish size may be a limitation for some users.

NWWS is one method used by radio and television broadcasters to activate the local Emergency Alert System (EAS).

To receive SBN/NOAAPORT Channel 201 requires:

  1. Satellite dish larger than 1.2m (minimum) for better reception (4.2m would offer the best reception)
  2. Low Noise Band (LNB) down converter (similar or better than Norsat 3220)
  3. DVB-S2 satellite receiver (similar or better than Novra S300)
  4. Windows-based PC with minimum 20GB storage and 3GB RAM
  5. Configure for SBN/NOAAPORT Channel 201 (NWWS products only) using CONFIGURATION sheet

To receive NWWS-Open Interface (OI) over the Internet requires:

  1. PC (Windows-7 or higher)
  2. 20 Gigabytes of memory for up to 60-day storage of all products
  3. 2 Gigahertz of greater multi-core processor
  4. NWS issued User_ID and password (see OI Request )
  5. XMPP Reader (i.e., Java, Pidgin, other XMPP application, etc)
     

Note: Additional programming is required with any XMPP reader in order to access the message details contained in the "stanzas" provided with each visible message header.

For NWWS-Open Interface message detail (other than just header information), XMPP reader software (commercial or user developed) is required.

Users may sign up for multiple accounts. If you decide to do so, please add a number after your last name (# or - #) and make the # the next in sequence (2, 3, etc..).

Remember: If multiple accounts are run from the same computer system the system will shut down.

Open Interface information:

  1. User_id and Password are case sensitive (and cannot be used on multiple machines). To request click here
  2. System and Network Firewall(s) may need adjustment.
  3. Port assignment is "5223"
  4. Router should be checked for proper configuration
  5. Protocol: XMPP
  6. Address: nwws-oi.weather.gov
  7. Group: chatroom "nwws"
  8. NWS has implemented some security measures. Now 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.
 Recommended format for the user agent string:

ApplicationName/vX.Y(http://your.app.url/; contact.email@example.com)

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.
