  4. A. How do hurricanes form? A hurricane forms when two opposing winds meet and begin to swirl over tropical oceans, usually between 5° and 20° north latitude. Around the middle of the low pressure area, warm, moist air, is forced aloft. As this air rises, it cools and condenses. The storm then becomes a large, swirling, low pressure system.

  8. Naming of Hurricanes • In 1953, the U.S. Weather Bureau officially started naming hurricanes after women--they were easy to pronounce, easy to remember, and were less likely to cause confusion than other methods. • In the late 1970’s, men’s names, as well as Hawaiian and Spanish names, were added. • Now alphabetical lists alternating male and female names are used (starting with A through W). • There are separate sets of names for hurricanes in the North Atlantic and for typhoons in the Pacific. • The lists of names for North Atlantic hurricanes are repeated every six years; if a hurricane has been especially deadly or damaging, its name is removed from the list.
