A wind advisory is generally issued by the National Weather Service of the United States when there are sustained non thunderstorm winds of 31–39 miles per hour (50–63 km/h) and/or gusts of 46–57 miles per hour (74–92 km/h) over land.
Winds over the said cap will trigger high wind alerts rather than a wind advisory.
The advisory is site specific, but winds of this magnitude occurring over an area that frequently experiences such wind speeds on a basis will not trigger a wind advisory.
[1] A slightly lower wind speed in areas around lakes may trigger a Lake wind advisory instead.
The following is an example of a Wind Advisory issued by the National Weather Service Office in Paducah, Kentucky on Sunday March 24, 2024.
