Cloud / ceiling flags
Every estimated cloud layer (and the ceiling) is flagged blue / red / pink based on its adjusted height above your facility — not the height as reported.
- Blue — estimated height below 1500 ft. Example:
BKN015reported at a station 200 ft lower adjusts to 1,300 ft. - Red — estimated height below 1000 ft. Example:
BKN010at KLUK (465 ft lower) adjusts to 535 ft for 8OH9. - Pink — estimated height below 500 ft. Example:
OVC008at a station 400 ft lower adjusts to 400 ft.
The flag is based on the adjusted (estimated) height, not the reported height, so a layer can change color once corrected for your facility's elevation. See How it works for the adjustment, and Visibility flags for the matching visibility scale.
