National Convective Weather Forecast (NCWF) Java Tool
The NCWF is an automatically generated depiction of: (1) current convection and (2) extrapolated significant current convection. It is a supplement to, but does not substitute for, the report and forecast information contained in convective SIGMETs.
NOTE: The recent release of Java (ver 1.7) breaks the ADDS Java applets on Windows XP and Vista.
We recommend that users either switch to the Flight Path Tool and select the Convection layer,
revert XP/Vista back to Java 1.6 or use Windows 7. Oracle Java 6 archives
