What is the valid time range for a Terminal Aerodrome Forecast (TAF)?

A Terminal Aerodrome Forecast (TAF) is a weather forecast specifically for the general aviation community and is focused on the conditions at an airport. The valid time range for a TAF is typically 24 to 30 hours. This forecast provides critical information on expected weather conditions, such as wind, visibility, significant weather, and changes in weather conditions that may affect aviation operations.

The 24 to 30-hour window allows pilots and air traffic controllers to plan for upcoming weather events that could impact flights, ensuring safety and efficiency in aviation. This extended forecast also helps address the dynamic nature of weather patterns that can affect flying conditions over a longer period than shorter forecasts.
