Area forecast
From Wikipedia, the free encyclopedia
An Aviation Area Forecast (FA or ARFOR) was a message product of the National Weather Service (NWS) in the United States. It has been replaced by Graphic Area Forecasts, or GFA, in 2017.[1]
There are also weather charts forecast like SIGWX. FA encompasses the weather conditions over a large regional area and is considered one of the better sources of information for en-route weather. It is also beneficial in verifying airport conditions at airports that do not have terminal aerodrome forecasts. FA's were issued three times daily in all 48 contiguous states of the United States, and modified as required. The NWS offices also issued FA's for Alaska and Hawaii, but Alaska used a slightly different format.
