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). The minimum surface pressure was 996 mb.

Tropical Cyclone Anggrek Spins Far South of Diego Garcia

Tropical Cyclone Anggrek continued to spin over the South Indian Ocean far to the south of Diego Garcia on Monday. At 4:00 p.m. EST on Monday the center of Tropical Cyclone Anggrek was located at latitude 26.9°S and longitude 71.2°E which put it about 1315 miles (2120 km) south of Diego Garcia. Anggrek was moving toward the south at 14 m.p.h. (22 km/h). The maximum sustained wind speed was 120 m.p.h. (195 km/h) and there were wind gusts to 150 m.p.h. (240 km/h). The minimum surface pressure was 944 mb.

Tropical Cyclone Anggrek continued to be small, but powerful. A circular eye with a diameter of 16 miles (26 km) was at the center of Anggrek’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 revolved around the core of Anggrek’ circulation. Storms near the core generated upper level divergence that pumped mass away from the tropical cyclone.

The small circulation around Tropical Cyclone Anggrek was still symmetrical. Winds to hurricane/typhoon force extended out 45 miles (75 km) from the center of Anggrek’s circulation. Winds to tropical storm force extended out 85 miles (135 km) from the center of circulation. The Hurricane Intensity Index (HII) for Tropical Cyclone Anggrek was 22.1. The Hurricane Size Index (HSI) was 13.8 and the Hurricane Wind Intensity Size Index (HWISI) was 35.9.

Tropical Cyclone Anggrek will move through an environment unfavorable for a strong tropical cyclone during the next 24 hours. Anggrek will move over water where the Sea Surface Temperatures are near 25°C. It will move under the eastern side of an upper level trough that is east of Madagascar. The upper level trough will produce northwesterly winds that will blow toward the top of Anggrek’s circulation. Those winds will cause the vertical wind shear to increase. The combination of cooler water and more vertical wind shear will cause Tropical Cyclone Anggrek to weaken during the next 24 hours. The combination of cooler water and more wind shear will also cause Anggrek to start to make a transition to an extratropical cyclone.

The upper level trough east of Madagascar will steer Tropical Cyclone Anggrek toward the southeast during the next 24 hours. On its anticipated track, Tropical Cyclone Anggrek will move farther away from Diego Garcia.

Tropical Cyclone Anggrek Intensifies to Equivalent of Cat. 4 Hurricane

Tropical Cyclone Anggrek intensified to the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale over the South Indian Ocean far to the south of Diego Garcia on Sunday. At 4:00 p.m. EST on Sunday the center of Tropical Cyclone Anggrek was located at latitude 22.2°S and longitude 72.7°E which put it about 1010 miles (1625 km) south of Diego Garcia.

The minimum surface pressure was 950 mb.

Tropical Cyclone Anggrek was small, but powerful. A circular eye with a diameter of 17 miles (28 km) was at the center of Anggrek’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 revolved around the core of Anggrek’ circulation. Storms near the core generated upper level divergence that pumped mass away from the tropical cyclone. The upper level divergence pumped away more mass than was converging in the lower levels of Tropical Cyclone Anggrek. The removal of mass caused the surface pressure to decrease.

The small circulation around Tropical Cyclone Anggrek was very symmetrical. Winds to hurricane/typhoon force extended out 25 miles (40 km) from the center of Anggrek’s circulation. Winds to tropical storm force extended out 100 miles (160 km) from the center of circulation. The Hurricane Intensity Index (HII) for Tropical Cyclone Anggrek was 25.1. The Hurricane Size Index (HSI) was 8.7 and the Hurricane Wind Intensity Size Index (HWISI) was 33.8.

Tropical Cyclone Anggrek will move through an environment favorable for a strong tropical cyclone during the next 24 hours. Anggrek will move over water where the Sea Surface Temperatures are near 28°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 Anggrek intensify during the next 24 hours. However, if the inner end of a rainband wraps around the existing eye and eyewall, then concentric eyewalls could form. If concentric eyewalls form, then an eyewall replacement cycle could cause Anggrek to start to weakeny.

Tropical Cyclone Anggrek will move around the western part of a high pressure system over the South Indian Ocean. The high pressure system will steer Anggrek toward the south during the next 24 hours. On its anticipated track, Tropical Cyclone Anggrek will move farther away from Diego Garcia.

The minimum surface pressure was 965 mb.

Tropical Cyclone Anggrek continued to be the equivalent of a major hurricane as it churned over the South Indian Ocean on Saturday. A very small circular eye was present at the center of Anggrek’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 revolved around the core of Anggrek’ circulation. Storms near the core generated upper level divergence that pumped mass away from the tropical cyclone. The upper level divergence was almost in balance with the convergence in the lower atmosphere and the intensity of Tropical Cyclone Anggrek was nearly constant during the past 24 hours.

The circulation around Tropical Cyclone Anggrek was small. Winds to hurricane/typhoon force extended out 25 miles (40 km) from the center of Anggrek’s circulation. Winds to tropical storm force extended out 90 miles (150 km) from the center of circulation. The Hurricane Intensity Index (HII) for Tropical Cyclone Anggrek was 20.6. The Hurricane Size Index (HSI) was 7.7 and the Hurricane Wind Intensity Size Index (HWISI) was 28.3.

Tropical Cyclone Anggrek will move through an environment 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 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 Anggrek is in an equilibrium with its environment, but Anggrek could intensify a little during the next 24 hours. However, if the inner end of a rainband wraps around the existing eye and eyewall, then concentric eyewalls could form. If concentric eyewalls form, then an eyewall replacement cycle could cause Anggrek to weaken temporarily.

Tropical Cyclone Anggrek will move around the northwestern part of a high pressure system over the South Indian Ocean. The high pressure system will steer Anggrek toward the west-southwest during the next 24 hours. On its anticipated track, Tropical Cyclone Anggrek will remain far to the south of Diego Garcia.

Elsewhere over the South Indian Ocean, Tropical Cyclone Candice weakened rapidly south-southeast of Mauritius.

The minimum surface pressure was 1000 mb.

Tropical Cyclone Anggrek continued to meander over the same part of the South Indian Ocean on Monday. The slow meandering motion of Anggrek allowed the winds near the surface of the South Indian Ocean to mix more cooler water to the surface. The cooler water limited the flow of energy from the surface to the atmosphere. Many of the remaining thunderstorms in Anggrek’s circulation weakened. Some thunderstorms were still occurring in bands in the northern part of Tropical Cyclone Anggrek. Winds to tropical storm force extended out 80 miles (130 km) from the center of Anggrek’s circulation

Tropical Cyclone Anggrek will move through an environment that should become more favorable for intensification during the next 24 hours. Anggrek will move over water where the Sea Surface Temperatures are near 28°C, when it moves away from the cooler water that has mixed to the surface. Tropical Cyclone Anggrek will move under the northern part of an upper level ridge over the South Indian Ocean. The upper level ridge will produce easterly winds that will blow toward the top of Anggrek’s circulation. Those winds will cause moderate vertical wind shear. The wind shear will inhibit intensification but the shear might not be enough to prevent strengthening. Tropical Cyclone Anggrek strengthen during the next 24 hours.

Tropical Cyclone Anggrek will move around the northwestern part of a high pressure system west of Australia. The high pressure system west of Australia will steer Anggrek toward the southwest during the week 24 hours. On its anticipated track, Tropical Cyclone Anggrek will continue gradually move farther west of Cocos Islands.
