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.

Pilot feedback is requested during this experimental period, which is expected to continue until October 16, 2020. Please send your feedback to the NWS through the following survey: https://www.surveymonkey.com/r/AlaskanAvnGuidance

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.
