Alaska Aviation Guidance (AAG) is a completely automated and experimental product designed to provide a short-term projection of weather conditions at select locations based off of Local Aviation Model Output Statistics (LAMP). The goal of this product is to provide additional local aviation guidance to Alaska airports that have an AWOS or ASOS observations, but do not have Terminal Aerodrome Forecasts (TAF). The projection covers the next six hours, and is updated every hour at forty minutes past the hour.

AAG is intended for use under Visual Meteorological Conditions within the next 6 hours for flight times of two hours or less in duration. FAA regulations require AAG to be used in conjunction with METARs, Pilot Reports (PIREPs), the Area Forecast (FA), Significant Meteorological Information (SIGMETs) and Airmen's Meteorological Information (AIRMETs) to ensure the weather conditions at the estimated time of arrival will be at or above the minimums and operations can be conducted with the performance limitations of the aircraft.

Due to limitations in LAMP guidance, AAG will not include forecasts of convective activity, blowing snow, or smoke. If precipitation is forecast the operators should review all available weather information, including SIGMETs, weather radar, and satellite imagery, to determine if hazardous weather will be present when the aircraft arrives and plan appropriately.

Prior to every flight, pilots should gather all information vital to the nature of the flight. This site is informational in nature and is designed to assist pilots and aircrews for flight planning and weather familiarization. It may be used in conjunction with other preflight information sources needed to satisfy all the requirements of 14 CFR 91.103 and is not to be considered as a sole source of information to meet all preflight action. Pilots can complete their regulatory-compliant preflight briefing by using other automated resources or from Flight Service at or by calling 1-800-WX-BRIEF.

Alaska Aviation Guidance (AAG) is a completely automated and experimental product produced on non-operational National Weather Service systems. As such, this guidance may not be available at all times and may change without notice. This guidance will not be monitored or updated by National Weather Service forecasters, and should be used with caution.
