The TAF and MOS forecasts shown on the Airports page are selected based on the nearest available station within approximately a 50 nm radius. MOS forecasts are more commonly displayed due to the higher number of MOS stations compared to TAF stations.
MOS Forecast: If a MOS station is available, the forecast will show the airport identifier followed by "MOS" at the top of the MOS forecast.
TAF Forecast: If a TAF station is available, the forecast will display the airport identifier followed by "TAF" at the top of the TAF forecast.
Nearest or No TAF/MOS: When neither a TAF nor MOS forecast is available directly for the airport, the forecast view will display "NO OBSERVATION" or indicate the nearest station used, including its direction and distance from the selected airport.
