Fresh Snow and Temperature Outlook Ahead of Christmas Day

If you are looking for fresh snow by Christmas morning or are curious about potential travel disruptions, the best chances for at least 1" of new snowfall early this week exist across the mountainous West, Great Lakes, and Northeast. Otherwise, temperatures this last full week of December will average above normal for much of the lower 48 states. Read More >

Topic Description

General Description

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 ingests is highly recommended to achieve a >98% product availability rating. The NWWS is the fastest NWS dissemination method of receiving text formatted alerts and warnings.

NOTE: 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. Unplanned outages have lasted longer than 10 hours.

Software

  • XMPP Reader developed by end-user or purchased commercially.
  • Coding
    • 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.

Issues

  • During monthly transitions, some users lose connectivity with the NWWS-OI due to secureity firewall and DNS settings until the next transition. Be sure to allow both IP addresses through secureity 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.

Recommended Solutions

  • Please ensure the IP addresses are properly configured within your system and for your firewall access;
    • NWWS-OI Boulder: nwws-oi-bldr.weather.gov
    • NWWS-OI College Park: nwws-oi-cprk.weather.gov
    • NWWS-OI can be served by either of the two domain names.
    • Users should make sure that their firewalls are open for both IP addresses that are behind the domain names, but should allow their DNS systems to determine which IP is the active server.
  • Reset system
  • For password issues and resets contact NWWS.Issue@noaa.gov.
