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.
