Maximum sustained wind 50% of the geostrophic wind speed aloft; while over open water or ice, the reduction is between 10% and 30%. In most basins, maximum sustained winds are used to define their category. In the Atlantic and northeast Pacific oceans, the Saffir–Simpson scale is used. This scale can be used to determine possible storm surge and damage impact on land. In most basins, the category of the tropical cyclone (for example, tropical depression, tropical storm, hurricane/typhoon, super typhoon, depression, deep depression, intense tropical cyclone) is determined from the cyclone's maximum sustained wind. Only in Australia is this quantity not used to
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
