Cyclone Edzani (BOM Designation:03U, JTWC designation:07S) was the strongest storm of the 2009–10 South-West Indian Ocean cyclone season], and one of the strongest cyclones of the year 2010.
Early on January 1 2010, TCWC Perth reported that Tropical Low 03U had developed about 1200 km (745 mi) to the southwest of Jakarta, Indonesia. [1] The low was being moved slowly by a mid level ridge of pressure located to the southeast. [2] The tropical low was thought to be in a favorable environment to develop further with moderate vertical wind shear and was benefiting from a good mid level equatorward outflow. [2] 03U continued to develop with deep convection near the Low Level Circulation Center despite the moderate vertical wind shear. [3] 03U continued to benefit from a monsoonal flow through the shear. [4] 03U continued to drift westward, as it passed over longitude 90E on January 4. [5] RSMC La Reunion then took over responsibility of 03U, and dubbed it Tropical Disturbance 08. [6] 08 became ill-defined, and was under strong easterly shear on January 5. [7] The Mauritius Meteorological Center named Tropical Disturbance 08 as Moderate Tropical Storm Edzani on January 6. [8] Edzani was upgraded on January 7 to a Severe Tropical Storm, as it continued west south-west around a subtropical ridge. [9] Just hours after becoming Severe Tropical Storm, Edzani became Tropical Cyclone Edzani. [10] Yet again on January 7, Edzani was upgraded as it continued to intensify, becoming Intense Tropical Cyclone Edzani. [11] Edzani had turned more southwestward due to the subtropical ridge located to it's southeast. [11] On August 8, intensification began to slow as Edzani was expected to move into cooler waters. [12] Edzani continued to intensify, and midday on August 8, Edzani was upgraded to Very Intense Tropical Cyclone strength. [13] Edzani reached it's max intensity that day, as RSMC La Reunion noted that the eye temperature began to warm. [14] Edzani began to weaken on January 9, and underwent an eyewall replacement cycle. [15] On January 10, Edzani weakened to tropical cyclone status, and the eye was lost. [16] Westerly shear increased over Edzani as it began to track more southward, and it became a Severe tropical storm. [17] Edzani began extratropical transition on January 11. [18] It became fully extratropical the next day, and RSMC La Reunion issued it's last advisory on the 13th.
