What wind speed categorizes a gale warning?

A gale warning is issued when wind speeds are forecasted to be between 34 and 47 knots. In maritime terms, a gale indicates sustained winds that can significantly affect navigation and operations at sea. This category of wind is strong enough to create rough seas and pose hazards to smaller vessels, making it essential for mariners to be aware of such conditions to ensure safety.

The ranges for other classifications of wind speed further clarify why the range of 34 to 47 knots is specifically called a gale. For instance, wind speeds above 48 knots are considered strong gales and can induce even more severe conditions, while speeds of 64 knots and above represent storms. Conversely, speeds below 34 knots do not warrant a gale warning, and thus this range effectively categorizes wind conditions that can severely impact maritime activities.

Understanding these classifications helps mariners assess the risks associated with weather conditions and make informed decisions on navigation and safety procedures.
