Juneau Wind Hazard Information System

The Juneau Wind Hazard Information System, consisting of a network of wind sensors (anemometers) and other equipment around the Gastineau Channel and the Juneau airport, is used to provide research data to determine if wind shear and turbulence could be predicted in and around the Juneau International Airport area. While the research is being conducted, the information from the anemometers is available to the flying public through Juneau Automated Flight Service Station. The anemometers will be in an "operational test" mode until the FAA certifies the anemometers.
During inflight and preflight briefings the AFSS specialist can provide, upon request, wind speed and wind direction for the following locations:
| Location | Elevation (MSL) |
| Eaglecrest | 2,624 ft. |
| Mount Roberts | 1,761 ft. |
| Sheep Mountain | 3,542 ft. |
| Pederson Hill (The Cut) | 492 ft. |
Example: "Eaglecrest operational test, wind one two zero at four five".
Wind direction is in reference to magnetic north and wind speed is in knots and is based on a one-minute average.
A Notice to Airman (NOTAM) will be issued whenever an anemometer is not functioning within normal parameters. During an inflight or preflight briefing the statement, "Eaglecrest wind not available", would indicate an outage and a NOTAM would be issued:
Example: JNU 03/001 JNU EAGLECREST WND NOT AVBL
Please do not hesitate to call Juneau AFSS at 1-800-WX-BRIEF (992-7433) or local call in Juneau at 789-7380, for a complete pilot weather briefing.
