Corrected FKUS65 and FKUS66 to FXUS65 and FXUS66

 

Effective April 14, 2016, at 1500 Coordinated Universal Time

(UTC), 1100 a.m. Eastern Daylight Time, the NWS will begin using

the FXUS66 KKCI administrative message to provide users a

generic, machine parsable notification that a correction was

sent for the World Area Forecast System (WAFS) Significant

Weather Charts.The format will be the same as the format

previously used in the FXUS65 administrative message to notify

WAFS users of corrections.The previously used FXUS65 message

will continue to be issued for corrections as well, but will be

in a free text format that will identify the features that were

corrected on the charts.

This change aligns World Area Forecast Center (WAFC) Washington

correction procedure with WAFC Londonís procedures and

International Civil Aviation Organization (ICAO) policy.
