A ship in a force 12 ("hurricane-force") storm at sea, the highest rated on the Beaufort scale. The Beaufort scale (/ ˈ b oʊ f ər t / BOH-fərt) is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale.
A gale warning is an alert issued by national weather forecasting agencies around the world in an event that maritime locations currently or imminently experiencing winds of gale force on the Beaufort scale. [1] Gale warnings (and gale watches) allow mariners to take precautionary actions to ensure their safety at sea or to seek safe anchorage ...
A gale is a strong wind; the word is typically used as a descriptor in nautical contexts. The U.S. National Weather Service defines a gale as sustained surface wind moving at a speed between 34 and 47 knots (63.0 and 87.0 km/h ; 17.5 and 24.2 m/s ; 39.1 and 54.1 mph ). [ 1 ]
Conversely, winds just above this intensity (39–57 miles per hour) are called "gale-force", and have a separate associated warning. Occasionally an informal lesser advisory, known as "small craft exercise caution", is issued for wind speeds lighter than those that call for a small craft advisory.
Hundreds of people were being evacuated from their homes and schools closed in parts of Scotland on Thursday, as much of northern Europe braced for stormy weather, heavy rain and gale-force winds ...
These watches are upgraded to tropical storm warnings, when gale and storm force winds become expected to occur somewhere in the warning area within 36 hours. [7] Hurricane watches are issued when sustained winds of 64 knots (74 mph; 119 km/h) are possible, within 48 hours in a specified area in association with a tropical, subtropical or post ...
Tropical storm watch TRA – Tropical storm conditions (gale- and storm-force sustained winds of 34 to 63 knots [39 to 72 mph; 63 to 117 km/h]) are possible within the specified coastal or inland area within 48 hours in advance of the forecast onset of tropical-storm-force winds. These winds may be accompanied by storm surge, and coastal and/or ...
The findings announced on Tuesday are part of a years-long study of the history of the cosmos focusing upon dark energy, an invisible and enigmatic force that is accelerating the ongoing expansion ...
