Atlantic hurricane

An Atlantic hurricane is a type of tropical cyclone that forms in the Atlantic Ocean primarily between June and November. These storms are continuously rotating around a low pressure center, which causes stormy weather across a large area, which is not limited to just the eye of the storm. They are organized systems of clouds and thunderstorms that originate over tropical or subtropical waters and have closed low-level circulation. An Atlantic tropical cyclone can be categorized by intensity. Tropical storms have one-minute maximum sustained winds of at least 39 mph (34 knots, 17 m/s, 63 km/h), while hurricanes must achieve the target of one-minute maximum sustained winds that is 75 mph or more (64 knots, 33 m/s, 119 km/h). Until the mid-1900s, storms were named arbitrarily. The practice of naming storms from a pre determined list began in 1953. Hurricanes that result in significant damage or casualties may have their names retired from the list. On average, 14 named storms occur each season in the North Atlantic basin, with 7 becoming hurricanes and 3 becoming major hurricanes (Category 3 or greater). In April 2004, Catarina became the first storm of hurricane strength to be recorded in the South Atlantic Ocean.
