30 hour TAFs: A slight change to the TAF format

Added on: March 27, 2008         Duration: 7 minutes

Terminal aerodrome forecasts, better known as TAFs are issued 4 times daily and represents a forecast for the expected meteorological conditions at an airport that are significant to aviation for a specified period of time. Normally this period is 24 hours. While 24 hours will still be the norm, on November 5, 2008, 32 high impact airports were extended to 30 hours. This has triggered a slight change to the format of all 666 TAFs issued by the NWS. Now all forecast groups within the body of the TAF must have a date and a time. This change in format will affect all TAFs issued by the NWS. In this workshop you'll learn the new TAF format and why this change was necessary.
