A tropical wave moved off the west African coast on September 19. On September 20, the wave organized enough to become Tropical Depression Ten, while 140 miles southwest of the coast of Guinea-Bissau. Since 1886, only one tropical cyclone in the Atlantic basin has formed further east than Jeanne did -- this was Tropical Storm Christine of 1973. After forming, the depression moved west-northwest, and became Tropical Storm Jeanne on September 21. Despite being in a slight shearing environment, Jeanne began to intensify at a faster pace, and by 1800 UTC on September 21, Jeanne attained hurricane status, while centered 120 miles southwest of the Cape Verde Islands. Jeanne continued to the west-northwest, and reached its peak intensity of 105 mph while about 580 miles west of the westernmost portion of the Cape Verde Islands. Jeanne's foward speed slowed, and on September 25, it began to turn to the northwest, then north later on.
Jeanne began to weaken on September 25 and 26, mainly due to strong vertical wind shear from the southwest. This shear was due to a trough. Under the influence of the trough, Jeanne to the north-northeast on September 28. Jeanne re-strengthened to a 90 mph hurricane as it was located 550 miles southwest of the Azores. Jeanne moved north-northeast, then east-northeast on September 29, and its foward speed slowed down and it weakened to a tropical storm. Jeanne continued east-northeast, gradually weakening as it did so. Around 0000 UTC on October 1, Jeanne reached the Azores, but by that time, Jeanne degenerated to a tropical depression, and was rapidly becoming extratropical. Jeanne became extratropical on October 1, the extratropical low moved eastward, generating gale-force winds until reaching the coast of Portugal just to the north of Lisbon around 0000 UTC on October 4. Later that day, Jeanne's extratropical remnants became unidentifiable over Spain.
Lack of Retirement
Because damage was minimal, the name Jeanne was not retired in the Spring of 1999 by the World Meteorological Organization. It was retired in 2004, however, and replaced with Julia for the 2010 Atlantic hurricane season.
