Subject: Soliciting Comments on Termination of the National
Convective Weather Diagnostic and Forecast Product (NCWD/NCWF)
until September 30, 2017
The NWS is accepting comments until September 30, 2017, on a
proposal to terminate the National Convective Weather Diagnostic
and Forecast Product (NCWD/NCWF). Users are encouraged to email
comments regarding this proposal to:
The NCWF is an automatically generated depiction of current convection
and extrapolated significant current convection. It is a supplement to,
but does not substitute for, the report and forecast information
contained in Convective forecasts. The NWS Aviation Weather Center (AWC)
updates the NCWD/F based on input from the Next Generation Weather Radar
(NEXRAD) and cloud-to-ground (CG) lightning data. The NCWF is updated
every 5 minutes using the most current available data from the NEXRAD
Composites delivered by Unisys and CG lightning.
The NCWD and NCWF product are online visually and through NOAAPort using
the headers WMO ZDIAT98 KKCI/JSAT98 KKCI.
Due to radar composite data termination and outdated computing servers
presenting IT security risks, this product has become unsupportable and
Alternatives to the NCWD and NCWF include the Multi-Radar/Multi-Sensor
System (MRMS) and the NWS AutoNowcaster available through the NWS.
A Service Change Notice (SCN) will be sent before terminating this product.
