Gale watch
A gale watch is issued by the National Weather Service of the United States when there is an increased risk for a gale-force wind event, meaning sustained surface winds, or frequent gusts, of 34 to 47 knots (39 to 54 mph or 63 km/h to 87 km/h), but the occurrence, location, and/or timing of the event is still uncertain, though the area it may effect is known.[1] A gale watch may precede a gale warning.
