Leave a reply

Tropical Cyclone Dikeledi passed far to the south of La Reunion on Thursday.  At 4:00 p.m. EST on Thursday the center of Tropical Cyclone Dikeledi was located at latitude 32.3°S and longitude 50.3°E which put the center about 795 miles (1235 km) south-southwest of St. Denis, La Reunion.  Dikeledi was moving toward the east-southeast at 23 m.p.h. (37 km/h).  The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 105 m.p.h. (165 km/h).  The minimum surface pressure was 979 mb.

Tropical Cyclone Dikeledi began to make a transition to an extratropical cyclone on Thursday as it moved over the Southwest Indian Ocean far to the south of La Reunion.  An eye was no longer visible at the center of Dikeledi’s circulation.  Microwave satellite images still showed evidence of the former eyewall.  The strongest winds were occurring in the former eyewall.  Thunderstorms were occurring in bands in the southeastern part of Tropical Cyclone Dikeledi.  Bands in the other parts of Dikeledi’s circulation consisted primarily of showers and lower clouds.

The size of the circulation around Tropical Cyclone Dikeledi increased on Thursday, when Dikeledi started the transition to an extratropical cyclone.  Winds to hurricane/typhoon force extended out 40 miles (65 km) from the center of Tropical Cyclone Dikeledi.  Winds to tropical storm force extended out 150 miles (240 km) from the center of Dikeledi.

Tropical Cyclone Dikeledi will move through an environment that will be unfavorable for intensification during the next 24 hours.  Dikeledi will move over water where where the Sea Surface Temperatures are near 25°C.  It will move under the eastern side of an upper level trough over southern Africa.  The upper level trough will produce northwesterly winds that will blow toward the top of Dikeledi’s circulation.  Those winds will cause moderate vertical wind shear.  Tropical Cyclone Dikeledi will weaken during the next 24 hours.  Cooler Sea Surface Temperatures and moderate vertical wind shear will cause Dikeledi to continue to make a transition to an extratropical cyclone.

The upper level trough over southern Africa will steer Tropical Cyclone Dikeledi toward the east-southeast during the next 24 hours.  On its anticipated track, Tropical Cyclone Dikeldi will pass far to the south of Mauritius on Friday.

Tropical Cyclone Dikeledi passed southwest of Madagascar on Wednesday.  At 4:00 p.m. EST on Wednesday the center of Tropical Cyclone Dikeledi was located at latitude 26.4°S and longitude 42.9°E which put the center about 150 miles (240 km) southwest of Beloha, Madagascar.  Dikeledi was moving toward the south-southeast at 22 m.p.h. (35 km/h).  The maximum sustained wind speed was 100 m.p.h. (160 km/h) and there were wind gusts to 120 m.p.h. (195 km/h).  The minimum surface pressure was 963 mb.

Tropical Cyclone Dikeledi intensified on Wednesday as it moved southwest of Madagascar.  A circular eye with a diameter of 25 miles (40 km) formed at the center of Dikeledi’s circulation.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Dikeledi.  Storms near the core of Dikeledi generated upper level divergence that pumped mass away from the tropical cyclone.  The removal of mass caused the surface pressure to decrease.

The size of the circulation around Tropical Cyclone Dikeledi increased on Wednesday.  Winds to hurricane/typhoon force extended out 25 miles (40 km) from the center of Dikeledi’s circulation.  Winds to tropical storm force extended out 150 miles (240 km) in the eastern side of Tropical Cyclone Dikeledi.  Winds to tropical storm force only extended out 60 miles (95 km) in the western side of Dikeledi.

The Hurricane Intensity Index (HII) for Tropical Cyclone Dikeledi was 16.5.  The Hurricane Size Index (HSI) was 11.8 and the Hurricane Wind intensity Size INdex (HWISI) was 28.3.  Tropical Cyclone Dikeledi was similar in size and intensity to Hurricane Idalia when Idalia hit Florida in 2023.

Bands in the eastern side of Tropical Cyclone Dikeledi were bring gusty winds and heavy rain to southern Madagascar.  Heavy rain could cause flash floods in some locations.

Tropical Cyclone Dikeledi will move through an environment that will become unfavorable for intensification during the next 24 hours.  Dikeledi will move over water where where the Sea Surface Temperatures are near 28°C.  It will move under the eastern side of an upper level trough over southern Africa.  The upper level trough will produce northwesterly winds that will blow toward the top of Dikeledi’s circulation.  Those winds will cause the vertical wind shear to increase.  Tropical Cyclone Dikeledi will weaken when the wind shear increases.

The upper level trough over southern Africa will steer Tropical Cyclone Dikeledi toward the southeast during the next 24 hours.  On its anticipated track, Tropical Cyclone Dikeldi will pass south of Madagascar.  Dikeledi will move southeast of Madagascar on Thursday.
