Speed comparison Weather Wire and EMWIN

Several users have asked me about the speed differences between Weather Wire (NWWS) and EMWIN.  The following table shows a quick comparison.  It appears that Weather Wire is faster.  Both systems deliver products very quickly.  I will note that EMWIN carries graphics that are not available from Weather Wire.  Weather Wire only carries text products.

Product Identifier NWWS Received Time EMWIN Received Time Difference in Seconds
HWOBMX 05:14:01.50 05:15:09.92 68
SVRMLB 11:43:09.68 11:43:51.18 42
SVRMFL 12:08:05.29 12:08:47.75 42

If receiving weather products is critical to your mission, I recommend using both ingest engines.  Weather Message will filter out duplicate products.

New NOAA Weather Wire Service (NWWS-2) in Production

The next generation NOAA Weather Wire Service (NWWS-2) is now in production.  The system features a C-Band and Internet feed.  You can find more information about the new NWWS at http://www.nws.noaa.gov/nwws/.  Click on the future configuration button.

For those of you using the WeatherWire Internet feed.  Weather Message will support the new Internet feed in the next software release.  You will need to go ahead and request your user name and password from the NWWS program manager Gregory Zwicker.  Send your request to Gregory.Zwicker@noaa.gov.

The legacy CSC service will end June 30, 2015. NWWS users must use NWWS-2 compatible hardware configurations and client software by that date to continue receiving NWWS alerts and warnings.
