Beaufort scale used in Taiwan and mainland China, which are often affected by typhoons. Internationally, WMO Manual on Marine Meteorological Services (2012 edition) defined the Beaufort Scale only up to force 12 and there was no recommendation on the use of the extended scale. Wind speed on the 1946 Beaufort scale is based on the empirical relationship: Where "v" is the equivalent wind speed at 10 metres above the sea surface and "B" is Beaufort scale number. For example, "B" = 9.5 is related to 24.5 m/s which is equal to the lower limit of "10 Beaufort". Using this formula the highest
1942 Belize hurricane and eventually curved southeastward. Around 1200 UTC on November 11, the system made another landfall near Campeche, Campeche with winds of 45 mph (75 km/h). Less than six hours later, the storm weakened to a tropical depression and dissipated shortly thereafter. In the Bahamas, a barometric pressure reading of and force 9 sustained winds on the Beaufort scale were observed on at Georgetown on Exuma. No damage was reported in that country. Strong winds were reported in some areas of Cuba. Cayo Paredon Grande in Camagüey Province recorded sustained winds of , while the city of Camagüey observed wind gusts
