National Convective Weather Forecast - Availability and Use
The NCWF is available primarily via the Internet from the AWC Aviation Digital Data Service (ADDS) at http://adds.aviationweather.noaa.gov/. Used in conjunction with other weather products such as Convective SIGMETs, the NCWF provides additional information for convective weather avoidance and flight planning.
The NCWF access by Automated Flight Service Stations and their associated En Route Flight Advisory Service facilities, Air Route Traffic Control Centers (ARTCCs) or Terminal Radar Approach Controls is planned but NOT currently available. (Note: See AIM Paragraph 7-1-15 for further information on ATC Inflight Weather Avoidance.)
