Gale: A storm or squall that may produce strong gusty winds or wind shifts.
Gale Force: The U.S. government's National Weather Service defines a gale as 34–47 knots (63–87 km/h, 17.5–24.2 m/s or 39–54 miles/hour) of sustained surface winds. Other sources use minimums as low as 28 knots (52 km/h) and maximums as high as 90 knots (170 km/h). Through 1986, the National Hurricane Center used the term gale to refer to winds of tropical storm force for coastal areas, between 33 knots (61 km/h) and 63 knots (117 km/h). The 90-knot (170 km/h) definition is very non-standard. A common alternative definition of the maximum is 55 knots (102 km/h).
