Tropical Cyclone Neville Weakens Over South Indian Ocean

Tropical Cyclone Neville weakened over the South Indian Ocean on Sunday. At 11:00 a.m. EDT on Sunday the center of Tropical Cyclone Neville was located at latitude 23.5°S and longitude 88.8°E which put it about 930 miles (1500 km) south-southwest of the Cocos Islands. Neville was moving toward the southwest at 10 m.p.h. (16 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 1002 mb.

Tropical Cyclone Neville was weakening rapidly over the South Indian Ocean on Sunday. Neville was under the eastern part of an upper level trough. The upper level trough was producing strong northwesterly winds that were blowing across the top of Neville’s circulation. Those winds were causing strong vertical wind shear. The strong wind shear was making the distribution of thunderstorms in Tropical Cyclone Neville asymmetrical. Thunderstorms were still occurring in the southeastern quadrant of Neville’s circulation. Bands in the other parts of Tropical Cyclone Neville consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 75 miles (120 km) from the center of circulation.

Tropical Cyclone Neville will move through an environment that will be unfavorable for intensification during the next 36 hours. Neville will move over water where the Sea Surface Temperatures are near 25°C. The upper level trough over the South Indian Ocean will continue to produce strong northwesterly winds that will blow toward the top of Neville’s circulation. Those winds will continue to cause strong vertical wind shear. Tropical Cyclone Neville will weaken during the next 36 hours.

Tropical Cyclone Neville will move around the northern side of a high pressure system over the South Indian Ocean. The high pressure system will steer Neville toward the west-southwest during the next 36 hours. On its anticipated track, Tropical Cyclone Neville will remain far southeast of Diego Garcia.

Tropical Cyclone Neville Passes South of Cocos Islands

Tropical Cyclone Neville passed south of the Cocos Islands on Saturday. At 11:00 a.m. EDT on Saturday the center of Tropical Cyclone Neville was located at latitude 20.8°S and longitude 93.1°E which put it about 630 miles (1015 km) south-southwest of the Cocos, Islands. Neville was moving toward the west-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 985 mb.

Tropical Cyclone Neville was weakening as it moved over the South Indian Ocean south of the Cocos Islands on Saturday. The distributions of thunderstorms and clouds in Neville was becoming asymmetrical. Some drier air appeared to be entering the northeastern part of Neville’s circulation. Thunderstorms were occurring in bands in the southern and western parts of Tropical Cyclone Neville. Bands in the northern and eastern parts of Neville’s circulation consisted primarily of showers and lower clouds.

Storms near the center of Tropical Cyclone Neville still generated upper level divergence that pumped mass away to the south of the tropical cyclone. Winds to hurricane/typhoon force extended out 25 miles (40 km) from the center of Neville’s circulation. Winds to tropical storm force extended out 130 miles (210 km) from the center of circulation.

Tropical Cyclone Neville will move through an environment that will be unfavorable for intensification during the next 24 hours. Neville will move over water where the Sea Surface Temperatures are near 28°C. However, an upper level trough over the South Indian Ocean will produce northwesterly winds that will blow toward the top of Neville’s circulation. Those winds will also cause the vertical wind shear to increase. Tropical Cyclone Neville will weaken during the next 24 hours.

Tropical Cyclone Neville will move around the northern side of a high pressure system over the South Indian Ocean. The high pressure system will steer Neville toward the west-southwest during the next 24 hours. On its anticipated track, Tropical Cyclone Neville will remain far southeast of Diego Garcia.

Tropical Cyclone Neville Spins Southeast of Cocos Islands

Tropical Cyclone Neville was spinning over the South Indian Ocean southeast of the Cocos Islands on Friday morning. At 11:00 a.m. EDT on Friday the center of Tropical Cyclone Neville was located at latitude 18.6°S and longitude 98.7°E which put it about 445 miles (720 km) south-southeast of the Cocos, Islands. Neville was moving toward the west-southwest at 16 m.p.h. (26 km/h). The maximum sustained wind speed was 105 m.p.h. (165 km/h) and there were wind gusts to 125 m.p.h. (200 km/h). The minimum surface pressure was 968 mb.

A small circular eye with a diameter of 10 miles (16 km) was at the center of Neville’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 center of Tropical Cyclone Neville. Storms near the center of Neville generated upper level divergence that pumped mass away from the tropical cyclone.

The circulation around Tropical Cyclone Neville was small. Winds to hurricane/typhoon force extended out 25 miles (40 km) from the center of Neville’s circulation. Winds to tropical storm force extended out 140 miles (220 km) from the center of circulation. The Hurricane Intensity Index (HII) for Tropical Cyclone Neville was 17.8. The Hurricane Size Index (HSI) was 9.0 and the Hurricane Wind Intensity Size Index (HWISI) was 26.8.

Tropical Cyclone Neville will move through an environment that will become less favorable for intensification during the next 24 hours. Neville will move over water where the Sea Surface Temperatures are near 28°C. An upper level trough over the South Indian Ocean will approach Neville’s circulation from the west. The upper level trough will produce northwesterly winds that will blow toward the top of Neville’s circulation. Those winds will also cause the vertical wind shear to increase. Tropical Cyclone Neville is likely to weaken when the vertical wind shear increases.

Tropical Cyclone Neville will move around the northern side of a high pressure system over the South Indian Ocean. The high pressure system will steer Neville toward the west-southwest during the next 24 hours. On its anticipated track, Tropical Cyclone Neville will pass south of the Cocos Islands later today.
