The primary source for expected weather information when a Terminal Forecast is unavailable is the Area Forecast. Area Forecasts provide a comprehensive overview of anticipated weather conditions across larger geographical areas and are beneficial for pilots when detailed terminal data is not accessible. These forecasts typically include information on significant weather phenomena, cloud cover, visibility, and expected surface winds, which are crucial for planning flights, particularly in areas that may be affected by broader weather patterns not confined to a specific airport.

The Weather Depiction Chart illustrates weather conditions but is more about current weather rather than forecasts. The Aeronautical Information Manual serves as a guide to aviation procedures and regulations but does not provide specific weather forecasts. The Radar Summary Chart displays real-time radar data about precipitation and storm intensity but does not offer forecasted weather information. Thus, the Area Forecast stands out as the most reliable choice for expected weather when a Terminal Forecast is not available.
