Meteorological Analysis
Jeanne originated from a tropical wave which slowly crawled off the coast of
Africa on September 19th. The tropical wave organized gradually as it moved
slowly west from Africa and became a tropical depression on the 21st, about
140 nm SW of Guinea-Bissau. Jeanne's origin point is the second furthest
east on record. The depression then moved WNW under the Azores high and
became tropical storm Jeanne on the 21st despite some light shear. Jeanne
continued to intensify and became a hurricane on the 22nd, about 120 nm SW
of the Cape Verde Islands. This was Jeanne's closest approach to the Cape
Verde Islands, and some stormy conditions came onshore there. Jeanne then
strengthened to its maximum intensity of 105 mph with a pressure of 969 mb
on the 24th, about 580 nm W of the Cape Verde Islands. A trough began to
interact with Jeanne on the 25th, causing more shear over the storm. Jeanne
turned more northerly on the 25th as well due to the trough. Shear then let up a bit
as Jeanne headed north, and Jeanne strengthened to a 90 mph hurricane on the
28th, about 550 nm WSW of the Azores. Jeanne then encountered the westerlies
on the 29th and veered east. Shear also increased dramatically over Jeanne,
causing Jeanne to weaken into a tropical storm by the 29th. Jeanne then moved
over the Azores on October 1st and caused a few gusts to tropical storm force there,
Jeanne weakened into a tropical depression though as it crossed the islands.
Cooler waters then caused Jeanne to become extratropical around the 1st, and
Jeanne impacted the Iberian peninsula on the 4th as a gale center. Jeanne
dissipated over Spain that day.
