SUBJECT: Changes to Collaborative Convective Forecast
Product (CCFP) valid times effective
March 1, 2013
NOTE: The following changes have no impact on
NOAA Weather
Wire Service
subscribers.
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

FAUS28 KKCI 4

On March 1, 2013,
NWS will cease issuance of the FAUS27 KKCI 2
hour forecast, and begin issuance of the FAUS30
