Tropical Cyclone Fabien moved southwest of Diego Garcia on Friday. At 11:00 a.m. EDT on Friday the center of Tropical Cyclone Fabien was located at latitude 10.2°S and longitude 69.6°E which put it about 285 miles (460 km) southwest of Diego Garcia. Fabien was moving toward the southwest at 5 m.p.h. (8 km/h). The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h). The minimum surface pressure was 993 mb.

Tropical Cyclone Fabien was maintaining its intensity on Friday morning as it moved southwest of Diego Garcia, but the distribution of thunderstorms was asymmetrical. Thunderstorms were occurring in bands in the southeastern quadrant of Fabien’s circulation. Bands in the other parts of Tropical Cyclone Fabien consisted primarily of showers and lower clouds. Drier air had wrapped around the western and northern sides of Fabien’s circulation and the drier air was causing the asymmetrical distribution of thunderstorms. Storms in the southeastern quadrant of Fabien still generated upper level divergence that pumped mass away to the southeast of the tropical cyclone. Winds to tropical storm force extended out 140 miles (225 km) in the northern side of Tropical Cyclone Fabien. Winds to tropical storm force extended out 60 miles (95 km) in the southern half of Fabien.

Tropical Cyclone Fabien will move through an environment that will become a little more favorable for intensification during the next 24 hours. Fabien will move over water where the Sea Surface Temperatures are near 27˚C. It will move into a region where the upper level winds are weaker and the vertical wind shear will decrease. The drier air in the western and northern parts of Tropical Cyclone Fabien will continue to inhibit intensification. Even with the effects of the drier air, Tropical Cyclone Fabien could intensify during the next 24 hours when the wind shear decreases.

Tropical Cyclone Fabien will move around the western side of a high pressure system over the South Indian Ocean. The high pressure system will steer Fabien slowly toward the southwest during the next 24 hours. On its anticipated track, Tropical Cyclone Fabien will move farther away from Diego Garcia. Fabien is likely to move toward the south during the weekend when it moves around the western end of the high pressure system.
