GRAFOR chart
Graphical aviation forecast - shows cloud / weather areas including freezing level across the country
81
GRAFOR chart validity time of components
Fixed validity
- Freezing level
- Fronts
- Cloud/weather areas delineated by thick green lines
Validity of +/- 3 hours to the fixed time
- Cloud/weather box
- Non-deep convective cloud
- Deep convective cloud
- Visibility + weather
82
GRAFOR Amendment
Amendments will be issued if there is widespread weather conditions not corresponding to the forecast, noted by AMD in the validity box as well as the reason for the amendment
83
GRAFOR validity times
Issued twice a day as a set of 3 covering a total period of 18 hours
- Issue 1 is made available at 1100Z and is valid for 1800Z, 0000Z and 6000Z
- Issue 2 is made available 2100Z and is valid for 0000Z, 6000Z and 1200Z
