Hurricane Ivan in the Far Eastern Atlantic Near Peak Intensity

A tropical wave moved off the coast of Africa and passed into the Atlantic Ocean on September 16. The wave had strong convection, and it organized and became Tropical Depression Nine when located about 175 miles southwest of the Cape Verde Islands late on September 18. At first, the depression was steered west by cyclonic flow over the Central Atlantic, but the flow came to a halt, and it was allowed to move to the northwest. The depression was slow to strengthen due to wind shear, but it managed to strengthen slowly into Tropical Storm Ivan by late on September 20. Ivan remained a minimal tropical storm for quite some time, and strengthening did not begin until it turned sharply to the north on September 21. The pressure fell steadily over the next few days as the storm returned to a northwesterly motion. Ivan became a hurricane late on September 23, despite entering progressively colder waters. After reaching hurricane strength, the storm began a wide curve that would eventually lead it eastward. When the storm completed the curve and began to accelerate to the east, it reached its peak intensity with winds of 90 mph and a pressure of 975 mbar. This was short-lived, however, and as the hurricane passed to the north of the Azores on September 27, it weakened to a tropical storm due to colder waters. The now tropical storm Ivan continued east for the next day, before becoming extratropical on September 28. The remnant degenerated into a gale that moved over the United Kingdom. No damages or casualties were reported due to Ivan.
