Tropical Cyclone Gezani weakened on Monday as it started to move away from southern Madagascar. At 4:00 p.m. EST on Monday the center of Tropical Cyclone Gezani was located at latitude 26.0°S and longitude 43.6°E which put the center about 150 miles (240 km) south of Toliara, Madagascar. Gezani was moving toward the east-southeast at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h). The minimum surface pressure was 984 mb.
Tropical Cyclone Gezani started to weaken on Monday. An upper level trough east of South Africa was producing strong northwesterly winds that were blowing toward the top of Gezani’s circulation. Those winds were causing strong vertical wind shear. The strong upper level winds were also blowing the tops off of thunderstorms in the northern and western parts of Tropical Cyclone Gezani. Bands in the northern and western parts of Gezani’s circulation consisted primarily of showers and lower clouds. Thunderstorms were still occurring in bands in the eastern and southern parts of Tropical Cyclone Gezani.
The strong vertical wind shear was also affecting the distribution of wind speeds around Tropical Cyclone Gezani, Winds to tropical storm force extended out 140 miles (225 km) in the southern half of Gezani’s circulation. Winds to tropical storm force extended out 70 miles (110 km) in the northern part of Tropical Cyclone Gezani.
Tropical Cyclone Gezani will move through an environment that will be unfavorable for intensification during the next 24 hours. Gezani will move over water where the Sea Surface Temperatures are near 28°C. However, the upper level trough that is east of South Africa will continue to cause strong vertical wind shear. Tropical Cyclone Gezani will continue to weaken during the next 24 hours because of the strong vertical wind shear. The vertical wind shear will also cause Gezani to continue to make a transition to an extratropical cyclone on Tuesday.
Tropical Cyclone Gezani will move around the western end of high pressure system that is over the South Indian Ocean. The high pressure system will steer Gezani toward the south during the next 24 hours. On its anticipated track, Tropical Cyclone Gezani will move farther away from southern Madagascar on Tuesday.
