What information may be included in a "Special TAF"?

A "Special TAF" is a type of Terminal Aerodrome Forecast that provides localized forecasts with greater detail than regular TAFs. These forecasts are issued when there are significant changes in expected weather conditions that are not covered by routine forecasts. For example, if severe weather is anticipated, such as thunderstorms or rapidly changing wind conditions, a special TAF will address these imminent weather phenomena at a specific aerodrome.

The emphasis on local forecasts allows pilots and airline operations to make informed decisions based on the imminent weather impact on takeoffs, landings, and overall flight safety. Such detailed information is crucial for professionals operating in the aviation industry, which is why a "Special TAF" is not general or international in scope, nor does it provide historical weather data. Each of these other topics falls outside the purpose of a Special TAF.
