Question: It seems like terminal area forecasts (TAFs) are amended more frequently these days. Is there a reason for this?
Answer: TAFs are issued by highly trained National Weather Service (NWS) meteorologists physically located at the 123 Weather Forecast Offices (WFOs) located throughout the U.S. and its territories. Each WFO issues a forecast for all airports serviced by a TAF within its county warning area (CWA). These areas are shown below.
For example, the Greenville-Spartanburg WFO in Greer, South Carolina, issues a TAF for six terminal areas to include, Charlotte Douglas International Airport (KCLT), Hickory Regional Airport (KHKY), Anderson Regional Airport (KAND), Asheville Regional Airport (KAVL), Greenville-Spartanburg International Airport (KGSP), and Greenville Downtown Airport (KGMU).
