Area forecast

An Aviation Area Forecast (FA or ARFOR) is a message product of the National Weather Service (NWS) in the United States. 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 are issued three times daily in all 48 contiguous states of the United States, and modified as required. The NWS offices also issue FA's for Alaska and Hawaii, but Alaska uses a slightly different format.
