Effective March 1, 2013, 0800 Coordinated Universal Time
(UTC), the NWS Aviation Weather Center (AWC) in Kansas City, MO, will adjust the valid times of the Collaborative Convective Forecast Product. On March 1, 2013 CCFP will change from the current valid times of 2 hours, 4 hours, and 6 hours from issuance time, to 4 hours, 6 hours, and 8 hours from issuance time. The Collaborative Convective Forecast Product (CCFP) is a forecast of expected convective weather at 4-, 6-, and 8-hours after issuance time, produced through a collaborative process involving NWS meteorologists at the AWC and Center Weather Service Units, and airline industry meteorologists. It is issued every 2 hours. The CCFP exists as direct support to the strategic, system-wide planning of FAA Traffic Flow Management intended to reduce traffic flow disruptions that may be caused by convective weather. The CCFP begins March 1 and runs through October 31 each year, covering the conterminous 48 United States and adjacent coastal waters. CCFP is issued as three separate ASCII text files under distinct World Meteorological Organization (WMO) headers. Current issued CCFP WMO Headers: FAUS27 KKCI 2 Hour Forecast FAUS28 KKCI 4 Hour Forecast FAUS29 KKCI 6 Hour Forecast On March 1, 2013, NWS will cease issuance of the FAUS27 KKCI 2 hour forecast, and begin issuance of the FAUS30 KKCI 8 hour forecast. NWS will continue the FAUS28 KKCI 4 Hour Forecast and FAUS29 KKCI 6 Hour Forecast. Effective March 1, 2013 issued CCFP WMO Headers:FAUS28 KKCI 4 Hour Forecast
