11. Wind reports from ships at sea have become increasingly based on anemometers, and less so on the Beaufort Scale . 12. The "'Beaufort scale "'is an empirical measure that relates wind speed to observed conditions at sea or on land. 13. On July 11, a nearby ship reported a pressure of and winds of Force 12 on the Beaufort scale . 14. The cover depicts the maritime storm warning flag indicating wind forces 10-12, the highest intensity on the Beaufort scale . 15. Winds were gusting at up to hurricane, force 12 on the Beaufort scale with waves up to high. 16. The wind gust were hitting 7 on the Beaufort scale , meaning a minimum of 50 kph ( 30 mph ). 17. Winds were gusting at up to hurricane force 12 on the Beaufort scale and whipping up waves high. 18. The weather deteriorated to Beaufort scale force 12 with winds at 70 to 90 knots and temperatures 40 below zero. 19. This may result in names being allocated to events that are below the traditional Beaufort scale definition of a storm. 20. There is a unique Beaufort Scale number and a unique Arrow Indication for each type of Wind Description mentioned above.
