TAFs stands for Terminal
Aerodrome Forecasts. In Zambia TAFs are produced four times
a day starting at approximately 30 minutes before each main
synoptic hour (00Z, 06Z,
12Z, and 18Z). All the forecasts
produced starting one hour before the main synoptic hour up
to four hours past the main synoptic hour are considered to
be for the same cycle. For example, forecasts produced between
1100Z and 1600Z are all
considered to be 12Z forecastss. In reality,
forecasts contain the starting and ending times for which
the forecast is valid. Our rule of thumb is that all forecasts
produced between (hh-1)00Z
to (hh+4)44Z
are considered to be for the hh cycle. The following table
summarizes the relationship between forecast production time
and cycle
