Tropical Cyclone Djoungou Develops North of Rodrigues

Tropical Cyclone Djoungou developed over the South Indian Ocean north of Rodrigues on Thursday. At 4:00 p.m. EST on Thursday the center of Tropical Cyclone Djoungou was located at latitude 15.3°S and longitude 65.1°E which put it about 315 miles (505 km) north-northeast of Port Mathurin, Rodrigues. Djoungou was moving toward the east at 7 m.p.h. (11 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 1001 mb.

A low pressure system over the South Indian Ocean north of Rodrigues strengthened on Thursday and Meteo France La Reunion designated the system as Tropical Cyclone Djoungou. The circulation around Djoungou was organizing quickly. The inner end of a rainband wrapped around the eastern and southern sides of the center of Tropical Cyclone Djoungou. Storms near the center of Djoungou’s circulation generated upper level divergence that pumped mass away from the tropical cyclone. Thunderstorms developed in bands in the northern and eastern parts of Tropical Cyclone Djoungou. Bands in the western part of Djoungou’s circulation consisted primarily of showers and lower clouds.

The distribution of wind speeds around Tropical Cyclone Djoungou was asymmetrical. Winds to tropical storm force extended out 175 miles (280 km) in the northeastern quadrant of Djoungou’s circulation. Winds to tropical storm force extended out 45 miles (75 km) in the southeastern quadrant of Tropical Cyclone Djoungou. The winds in the western half of Djoungou were blowing at less than tropical storm force.

Tropical Cyclone Djoungou will move through an environment very favorable for intensification during the next 24 hours. Djoungou will move over water where the Sea Surface Temperatures are near 29°C. It will move under the axis of an upper level ridge over the South Indian Ocean. The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear. Tropical Cyclone Djoungou will intensify during the next 24 hours. Djoungou could intensify rapidly at times. Tropical Cyclone Djoungou could strengthen to the equivalent of a major hurricane during the weekend.

Tropical Cyclone Djoungou will move around the southern side of a high pressure system over the South Indian Ocean. The high pressure system will steer Djoungou toward the east during the next 24 hours. On its anticipated track, Tropical Cyclone Djoungou will move farther away from Rodrigues. Djoungou could pass south of Diego Garcia in a few days.

Anggrek Transitions to an Extratropical Cyclone

Former Tropical Cyclone Anggrek made a transition to an extratropical cyclone over the South Indian Ocean during Tuesday night. At 4:00 a.m. EST on Wednesday the center of former Tropical Cyclone Anggrek was located at latitude 33.3°S and longitude 84.8°E which put it about 1925 miles (3105 km) south-southeast of Diego Garcia. Anggrek was moving toward the east-southeast at 40 m.p.h. (65 km/h). The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h). The minimum surface pressure was 983 mb.

Former Tropical Cyclone Anggrek made a transition to a powerful extratropical cyclone over the South Indian Ocean. Anggrek moved over water where the Sea Surface Temperatures are near 22°C. It moved under the eastern side of an upper level trough that is east of Madagascar. The upper level trough produced northwesterly winds that caused strong vertical wind shear. The combination of colder water and strong wind shear caused formal Tropical Cyclone Anggrek to make a transition to an extratropical cyclone.

The transition to an extratropical cyclone also caused changes to the structure of former Tropical Cyclone Anggrek. The strong northwesterly winds in the upper levels of the atmosphere blew the tops off of many of the thunderstorms in Anggrek’s circulation. Thunderstorms were still occurring in bands in the southern part of former Tropical Cyclone Anggrek. Bands in the northern part of the circulation consisted primarily of showers and lower clouds. Winds to hurricane/typhoon force extended out 70 miles (110 km) in the eastern side of former Tropical Cyclone Anggrek. Winds to tropical storm force extended out 140 miles (220 km) from the center of Anggrek’s circulation.

The upper level trough east of Madagascar will steer former Tropical Cyclone Anggrek quickly toward the east-southeast. On its anticipated track, Former Tropical Cyclone Anggrek could approach southwestern Australia later this week.

Elsewhere over the South Indian Ocean, a tropical depression formed east of Rodrigues. At 10:00 a.m. EST on Wednesday the center of the tropical depression was located at latitude 19.9°S and longitude 66.2°E which put it about 175 miles (280 km) east of Port Mathurin, Rodrigues. The tropical depression was moving toward the south-southeast at 3 m.p.h. (5 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).

Tropical Cyclone Anggrek exhibited a little more organization on Wednesday. The inner end of a rainband wrapped around the western and northern sides of the center of Anggrek’s circulation. Bands of showers and thunderstorms revolved around the center of Tropical Cyclone Anggrek. Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical cyclone. Winds to tropical storm force extended out 75 miles (120 km) from the center of Anggrek’s circulation.

Tropical Cyclone Anggrek will move through an environment somewhat favorable for intensification during the next 24 hours. Anggrek will move over water where the Sea Surface Temperatures are near 28°C. It will move under the western part of an upper level ridge over the eastern part of the South Indian Ocean. The upper level ridge will produce northerly winds that will blow toward the top of Anggrek’s circulation. Those winds will cause some vertical wind shear. The wind shear will inhibit intensification, but the shear may not be enough to prevent strengthening. Tropical Cyclone Anggrek could strengthen during the next 24 hours.

Tropical Cyclone Anggrek will move around the western part of a high pressure system west of Australia. The pressure system will start to steer Anggrek toward the south-southwest during the next 24 hours.

The minimum surface pressure was 989 mb.

Tropical Cyclone Belal began a transition to an extratropical cyclone on Tuesday as it moved over the Southwest Indian Ocean southeast of Mauritius. An upper level trough southeast of Madagascar was producing northwesterly winds that were blowing toward the top of Belal’s circulation. Those winds were causing strong vertical wind shear. The strong upper level winds were also tilting the upper part of Tropical Cyclone Belal to the southeast of the lower part of Belal’s circulation. The strong vertical wind shear also caused the distribution of thunderstorms in Tropical Cyclone Belal to become asymmetrical. Thunderstorms were occurring in bands in the southeastern part of Belal’s circulation. Bands in the other parts of Tropical Cyclone Belal consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 175 miles (280 km) from the center of Belal.

Tropical Cyclone Belal will move through an environment unfavorable for intensification during the next 36 hours. Belal will move over water where the Sea Surface Temperatures are near 26°C. The upper level trough southeast of Madagascar will continue to cause strong vertical wind shear. The strong wind shear will cause Belal to continue to weaken gradually. The strong vertical wind shear will also cause Tropical Cyclone Belal to continue to make a transition to an extratropical cyclone.

Tropical Cyclone Belal will move around the southern side of a high pressure system over the South Indian Ocean. The high pressure system will steer Belal toward the east-southeast during the next 36 hours. On its anticipated track, Tropical Cyclone Belal will pass south of Rodrigues on Wednesday.

Tropical Cyclone Freddy Hits Southern Mozambique

Tropical Cyclone Freddy hit southern Mozambique on Friday morning. At 10:00 a.m. EST on Friday the center of Tropical Cyclone Freddy was located at latitude 22.6°S and longitude 34.6°E which put it about 60 miles (95 km) southwest of Vilankulo, Mozambique. Freddy was moving toward the west at 16 m.p.h. (26 km/h). The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h). The minimum surface pressure was 991 mb.

Tropical Cyclone Freddy strengthened to the equivalent of a hurricane/typhoon before it hit the coast of southern Mozambique on Friday morning. The center of Freddy’s circulation made landfall on the coast about 40 miles (65 km) south of Vilankulo. A circular eye was at the center of circulation. A ring of thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the center of Tropical Cyclone Freddy. Winds to tropical storm force extended out 75 miles (120 km) from the center of circulation.

Tropical Cyclone Freddy will move north of a high pressure system over southern Africa. The high pressure system will steer Freddy toward the west during the next 24 hours. On its anticipated track Tropical Cyclone Freddy will move farther inland over southern Mozambique. The center of Freddy’s circulation will pass near Tesenane and Chigubo. Tropical Cyclone Freddy will weaken gradually as it moves farther inland. Freddy will produce gusty winds and heavy rain over southern Mozambique. Heavy rain could cause flash floods in some locations.

Elsewhere over the South Indian Ocean, Tropical Cyclone Enala moved east-southeast of Rodrigues. At 4:00 a.m. EST on Friday the center of Tropical Cyclone Enala was located at latitude 22.6°S and longitude 70.2°E which put it about 495 miles (800 km) east-southeast of Rodrigues. Enala was moving toward the south-southwest at 16 m.p.h. (26 km/h). The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h). The minimum surface pressure was 978 mb.

Tropical Cyclone Freddy Passes North of Rodrigues

Tropical Cyclone Freddy passed north of Rodrigues on Sunday morning. At 10:00 a.m. EST on Sunday the center of Tropical Cyclone Freddy was located at latitude 17.6°S and longitude 63.2°E which put it about 140 miles (225 km) north of Rodrigues. Freddy was moving toward the west-southwest at 18 m.p.h. (29 km/h). The maximum sustained wind speed was 150 m.p.h. (240 km/h) and there were wind gusts to 185 m.p.h. (295 km/h). The minimum surface pressure was 925 mb.

Tropical Cyclone Freddy was the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale as it passed north of Rodrigues on Sunday morning. Bands in the southern side of Freddy’s circulation brought gusty winds and rain to Rodrigues. A circular eye with a diameter of 30 miles (50 km) was at the center of Tropical Cyclone Freddy. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Freddy’s circulation. Storms near the core generated strong upper level divergence that pumped mass away from the tropical cyclone in all directions.

The circulation around Tropical Cyclone Freddy was very symmetrical. Winds to hurricane/typhoon force extended out 40 miles (65 km) from the center of Freddy’s circulation. Winds to tropical storm force extended out 100 miles (160 km) from the center of circulation. The Hurricane Intensity Index (HII) for Freddy was 31.6. The Hurricane Size Index (HSI) was 14.0 and the Hurricane Wind Intensity Size Index (HWISI) was 45.6. Tropical Cyclone Freddy was similar in size and intensity to Hurricane Ida, when Ida hit the coast of Louisiana in 2021. Freddy was capable of causing regional severe damage.

Tropical Cyclone Freddy will continue to move through an environment that will be favorable for a strong tropical cyclone during the next 24 hours. Freddy will move over over water where the Sea Surface Temperatures are near 28˚C. An upper level ridge over the South Indian Ocean will produce easterly winds that will blow toward the top of Freddy’s circulation. The winds in the lower levels of the atmosphere will also blow from the east. So, there will be little vertical wind shear. If the inner end of a rainband wraps around the existing eye and eyewall, then concentric eyewalls could form. Concentric eyewalls would likely cause an eyewall replacement cycle that would cause Tropical Cyclone Freddy to weaken temporarily.

Tropical Cyclone Freddy will move around the northern part of a high pressure system over the South Indian Ocean. The high pressure system will steer Freddy toward the west-southwest during the next 24 hours. On its anticipated track, Tropical Cyclone Freddy will be north of Mauritius in less than 24 hours. Freddy will continue to bring gusty winds and locally heavy rain to Rodrigues until it moves farther away. Tropical Cyclone Freddy will also affect Mauritius, La Reunion and Madagascar. Bands in the southern side of Freddy’s circulation will bring gusty winds and locally heavy rain to Mauritius and La Reunion on Monday. Heavy rain could cause flash floods in some locations. Tropical Cyclone Freddy will approach the east coast of Madagascar in 48 hours.
