HURRICANE ISIDORE

Hurricane Isidore


A tropical wave moved off the coast of Africa into the eastern waters of the Atlantic Ocean on September 22. The wave was initially well defined by a cyclonic circulation of clouds, and it was allowed to organize further during the next two days. Deep convection became more concentrated and persistent on September 23, and the wave was deemed Tropical Depression Nine midday on September 24. This depression was located south of a deep ridge initially, which kept the storm on a steady WNW track for the next few days. It was named Tropical Storm Isidore on September 25 when an intense band of convection became more centralized around the circulation. Isidore was able to strengthen quite rapidly in the next 24 hours, reaching hurricane status just 24 hours later on September 26. After becoming a hurricane, Isidore did not strengthen as rapidly, with winds increasing at about 5 mph intervals over the next few days. This intensification made the storm a powerful Category 3 with winds of 115 mph and a pressure of 960 mbar, which would be its peak intensity. By now, the steering currents had turned the storm to the north, which took Isidore into an unfavorable area for development. Plagued with wind shear and cooler waters, the eye became indistinguishable on September 29, and the storm weakened to a tropical storm later that day. Over the next few days, the center of circulation became exposed as convection faded away. Tropical Storm Isidore weakened to a depression on October 1, and then degenerated into an extratropical storm early on the 2nd of October in the far northern atlantic. No damages or deaths were reported due to Isidore, having never affected land.
