Tropical Storm Helene
The name Helene or Helena has been used for nine tropical cyclones worldwide: seven in the Atlantic Ocean, one in the South-West Indian Ocean, and one in the Western Pacific Ocean. In the Atlantic: * Hurricane Helene (1958) – a powerful storm that grazed Cape Hatteras causing $11 million in damage. * Tropical Storm Helena (1963) – between Dominica and Guadeloupe and struck Antigua. * Hurricane Helene (1988) – a Category 4 hurricane that stayed in the open sea, never threatening land. * Tropical Storm Helene (2000) – entered the Caribbean Sea, made landfall at Fort Walton Beach, Florida, exited at the North Carolina coast and regained tropical storm strength heading northeast. * Hurricane Helene (2006) – a Category 3 hurricane that stayed in the open ocean, never threatening land. * Tropical Storm Helene (2012) Tropical Storm Helene was a moderate tropical storm which affected the southern Caribbean and Central America in mid-August 2012.

Tropical Cyclone
A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean. In the Indian Ocean, South Pacific, or (rarely) South Atlantic, comparable storms are referred to simply as "tropical cyclones", and such storms in the Indian Ocean can also be called "severe cyclonic storms". "Tropical" refers to the geographical origin of these systems, which form almost exclusively over tropical seas. "Cyclone" refers to their winds moving in a circle, whirling round ...

Hurricane Helene (1958)
Hurricane Helene was the most intense tropical cyclone of the 1958 Atlantic hurricane season. The eighth tropical storm and fourth hurricane of the year, Helene was formed from a tropical wave east of the Lesser Antilles on September 21, 1958. Moving steadily westward, the storm slowly intensified, attaining hurricane strength on September 24. As conditions became increasingly favorable for tropical cyclone development, Helene began to rapidly intensify. Nearing the United States East Coast, the hurricane quickly attained Category 4 intensity on September 26, before it subsequently reached its peak intensity with maximum sustained winds of and a minimum barometric pressure of . The intense hurricane came within of Cape Fear, North Carolina before recurving out to sea. Accelerating northward, Helene gradually weakened, and transitioned into an extratropical cyclone as it passed over Newfoundland on September 29. Helene's extratropical remnants traversed e ...

Tropical Storm Helena
The 1963 Atlantic hurricane season featured one of the deadliest tropical cyclones on record in the Atlantic basin: Hurricane Flora. The season officially began on June 15, and lasted until November 15. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. It was a slightly below average season in terms of tropical storms, with a total of ten nameable storms. The first system, an unnamed tropical storm, developed over the Bahamas on June 1. In late July, Hurricane Arlene, developed between Cape Verde and the Lesser Antilles. The storm later impacted Bermuda, where strong winds resulted in about $300,000 (1963 USD) in damage. Other storms such as hurricanes Beulah and Debra, as well as an unnamed tropical storm, did not impact land. During the month of September, Tropical Storm Cindy caused wind damage and flooding in Texas, leaving three deaths and approximately $12.5 million in damage. Hurri ...

Hurricane Helene (1988)
The 1988 Atlantic hurricane season was a near average season that proved costly and deadly, with 15 tropical cyclones directly affecting land. The season officially began on June 1, 1988, and lasted until November 30, 1988, although activity began on May 30 when a tropical depression developed in the Caribbean. The June through November dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The first cyclone to attain tropical storm status was Alberto on August 8, nearly a month later than usual. The final storm of the year, Tropical Storm Keith, became extratropical on November 24. The season produced 19 tropical depressions of which 12 attained tropical storm status. One tropical storm was operationally classified as a tropical depression but was reclassified in post-analysis. Five tropical cyclones reached hurricane status of which three became major hurricanes reaching Category 3 on the Saffir†... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Storm Helene (2000)
Tropical Storm Helene was a long-lived tropical cyclone that oscillated for ten days between a tropical wave and a tropical storm. It was the twelfth tropical cyclone and eighth tropical storm of the 2000 Atlantic hurricane season, forming on September 15 east of the Windward Islands. After degenerating into a tropical wave, the system produced flooding and mudslides in Puerto Rico. It reformed into a tropical depression on September 19 south of Cuba, and crossed the western portion of the island the next day while on the verge of dissipation. However, it intensified into a tropical storm in the Gulf of Mexico, reaching its peak intensity while approaching the northern Gulf Coast. The storm rapidly weakened before moving ashore near Fort Walton Beach, Florida on September 22. It produced heavy rainfall along the Florida Panhandle that reached . The rains flooded hundreds of houses and caused the Sopchoppy River to reach a record crest. Gusty winds left about 5,000 peop ...

Hurricane Helene (2006)
Hurricane Helene was the ninth tropical cyclone, tropical storm, fourth hurricane, and strongest hurricane of the 2006 Atlantic hurricane season, tied with Hurricane Gordon (2006), Hurricane Gordon. Helene was a long-lived Cape Verde hurricane that formed in the extreme southeastern part of the North Atlantic Ocean, peaking as a Category 3 hurricane on the Saffir-Simpson hurricane scale as it traversed the central Atlantic. It never affected land until the very end of its lifespan as a weak extratropical system, which had minor impact in the northern British Isles. Meteorological history In the second week of September, a strong tropical wave began to emerge off the coast of Africa. It was well-organized from the start, and on September 11, even before it emerged off the coast, the National Hurricane Center predicted that it could quickly develop into a tropical depression. That is indeed what happened, and it became Tropical Depression Eight on the morning of September 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Storm Helene (2012)
Tropical Storm Helene was a moderate tropical storm which affected the southern Caribbean and Central America in mid-August 2012. The seventh tropical depression and eighth named storm of the 2012 Atlantic hurricane season, Helene was monitored as a tropical wave that exited the west coast of the African continent on August 5. It gradually moved westward and became a tropical depression east of the Lesser Antilles four days later. However, unfavorable conditions initially prevented it from developing, which led to its initial degeneration to a remnant low as it traversed the Caribbean Sea. Meteorological history Tropical Storm Helene originated from a tropical wave, with an accompanying area of low pressure, which moved off the west coast of Africa on August 5. The wave traversed westward with some cyclonic rotation occurring in the middle levels of the atmosphere and a large area of convection. Early on August 7, the National Hurricane Center (NHC) began to monitor the distur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Helene (2018)
The 2018 Atlantic hurricane season was the third in a consecutive series of above-average and damaging Atlantic hurricane seasons, featuring 15 named storms, 8 hurricanes, and 2 major hurricanes, which caused a total of over $50 billion (2018 USD) in damages and at least 172 deaths. More than 98% of the total damage was caused by two hurricanes (Florence and Michael). The season officially began on June 1, 2018, and ended on November 30, 2018. These dates historically describe the period in each year when most tropical cyclones form in the Atlantic basin and are adopted by convention. However, subtropical or tropical cyclogenesis is possible at any time of the year, as demonstrated by the formation of Tropical Storm Alberto on May 25, making this the fourth consecutive year in which a storm developed before the official start of the season. The season concluded with Oscar transitioning into an extratropical cyclone on October 31, almost a month before the official e ...

Cyclone Helene (1969)
In meteorology, a cyclone () is a large air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above (opposite to an anticyclone). Cyclones are characterized by inward-spiraling winds that rotate about a zone of low pressure. The largest low-pressure systems are polar vortices and extratropical cyclones of the largest scale (the synoptic scale). Warm-core cyclones such as tropical cyclones and subtropical cyclones also lie within the synoptic scale. Mesocyclones, tornadoes, and dust devils lie within smaller mesoscale. Upper level cyclones can exist without the presence of a surface low, and can pinch off from the base of the tropical upper tropospheric trough during the summer months in the Northern Hemisphere. Cyclones have also been seen on extraterrestrial planets, such as Mars, Jupiter, and Neptune. Cyclogenesis is the process of cyclone formati ...

1950 Pacific Typhoon Season
The 1950 Pacific typhoon season has no official bounds; it ran year-round in 1950, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1950 Pacific hurricane season. This would be the first season that Fleet Weather Center in Guam, predecessor agency to Joint Typhoon Warning Center, would take most of the responsibility in the basin, including naming the storms. Before this season, the storms are identified and named by the United States Armed Services, and these names are taken from the list that USAS publicly adopted before the 1945 season started.

Atlantic Hurricane Set Index Articles
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.
