Juneau Airport Wind System(JAWS)
The Juneau Airport Wind System, consists of a network of wind sensors (anemometers) and wind profilers around the Gastineau Channel and the Juneau airport. The purpose is to provide research data to determine if wind shear and turbulence can be predicted in and around the Juneau International Airport area. While research is being conducted, the information from the anemometers is available to the flying public through the Juneau Flight Service Station and online at http://pajk.arh.noaa.gov/jaws/jaws.php.
During inflight and preflight briefings the FSS 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. |
| Pederson Hill (The Cut) | 492 ft. |
| Sheep Mountain | 3,542 ft. |
Example: “Eaglecrest operational test, wind one two zero at four five”.
The wind direction is in reference to magnetic north and wind speed given 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 FSS at 1-866-297-2236 or, if in Juneau, at 789-7380, for a complete pilot weather briefing.
