A "gale warning" is a weather alert issued by meteorological agencies to inform the public about strong winds. Specifically, it indicates sustained wind speeds of 34 to 40 knots (39 to 46 miles per hour) or gusts reaching 43 to 54 knots (49 to 62 miles per hour). These warnings are crucial for mariners, as they signal potentially dangerous conditions at sea. Gale warnings are part of a broader system of weather advisories, which also includes alerts for storms and hurricanes. They help ensure safety for those involved in outdoor activities, including sailors and fishermen, by providing timely information about changing weather conditions.
