What does a Gale Warning primarily alert boaters to?

A Gale Warning primarily alerts boaters to winds becoming potentially dangerous. Specifically, this warning indicates sustained wind speeds between 34 and 40 knots (39 to 46 mph) or gusts reaching these levels. Such conditions can create hazardous situations on the water, including choppy waves and reduced maneuverability for vessels. Understanding the implications of this warning is crucial for boaters to ensure safety, as high winds can lead to loss of control and increased risks of capsizing or accidents. Therefore, recognizing a Gale Warning allows boaters to take appropriate precautions, such as returning to shore or securing their vessel to prevent accidents during these conditions.
