A Wind Advisory is generally issued by the National Weather Service of the United States when there are sustained 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. The product is site specific, but winds of this magnitude occurring over an area that frequently experiences such wind speeds will not trigger a wind advisory.
