1. Why should I use the NOAA Weather Wire Service (NWWS)?

  • NWWS is the fastest delivery method available to receive text weather forecasts alert and warning products from the National Weather Service(NWS). High priority weather warnings and watches are available to users within 10 seconds from the time they are issued to CSC by the NWS. Satellite dissemination via NOAAPORT is within 1-2 minutes of initial dissemination.

  • The NWWS data can be fed directly to telecommunications equipment for distribution to subscribers, other consumers, and the general public.

  • NWWS is available over satellite from CSC and NOAAPORT and via the Internet from CSC using an "open-interface (OI)" TCP/IP connection.

  • The NWWS-CSC satellite network is extremely reliable (and is independent of the Internet), with an availability of 99.9%.


2. What steps do I need to take to get the NWWS feed?

  • NWWS is available over two satellite links and over the Internet.

  • Satellite links require access to a correctly sized dish, equipment, and a comparable satellite receiver (http://www.csc.com/public_sector/ds/27517-nwws).

  • The current Internet access is a one-time fee or a monthly service fee through CSC and requires TCP/IP connection to a PC.  Specific software is needed in order to parse the data and a program written to filter for specific products.  CSC can provide the necessary programming and filtering as an additional service/cost.

3. What are the other NWWS products feed alternatives?

  • Family of Services (FOS) is a for fee service offered by NWS that offers ALL available products over TCP/IP connection to the clients PC.

5. What are the various product formats?

  • There are two basic formats.

    Text messages (alerts, watches, warnings and forecasts) are produced in World Meteorological Organization (WMO) format. Most NWS dissemination systems use/push WMO format. CSC modifies the WMO format slightly to accommodate clients' specific needs by adding line space or special character (WMO+).

    NOTE:
    Common Alert Protocol (CAP) v1.2 is under development and will be introduced late 2014. This is the same message format provided to FEMA (Federal Emergency Management Agency) for the current Wireless Emergency Alerts (WEA) from cellphone carriers
