Tropical Cyclone Faraji Weakens Southeast of Diego Garcia

Tropical Cyclone Faraji weakened southeast of Diego Garcia on Friday. At 4:00 p.m. EST on Friday the center of Tropical Cyclone Faraji was located at latitude 18.9°S and longitude 80.4°E which put it about 1000 miles (1610 km) south-southeast of Diego Garcia. Faraji was moving toward the west-southwest at 9 m.p.h. (15 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 987 mb.

An upper level low east of Madagascar produced strong northwesterly winds which blew toward the top of Tropical Cyclone Faraji on Friday. Those winds caused strong vertical wind shear and the winds blew the tops of many of the thunderstorms around Faraji. The strongest thunderstorms were occurring in bands southeast of the center of circulation. Bands in the other parts of Tropical Cyclone Faraji consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 90 miles (145 km) from the center of Faraji.

Tropical Cyclone Faraji will move into an environment that will be unfavorable for a tropical cyclone during the next 48 hours. Faraji will move over water where the Sea Surface Temperature is near 28°C. However, the upper level low east of Madagascar will continue to produce northwesterly winds which will blow toward the top of the tropical cyclone. Those winds will continue to cause the strong vertical wind shear. Tropical Cyclone Faraji will weaken during the next 48 hours..

Tropical Cyclone Faraji will move around the northern part of a subtropical high pressure system over the South Indian Ocean. The high will steer Faraji toward the west during the next few days. On its anticipated track Tropical Cyclone Faraji will pass well to the south of Diego Garcia.

Tropical Cyclone Faraji Churns Southeast of Diego Garcia

Tropical Cyclone Faraji churned southeast of Diego Garcia on Wednesday. At 4:00 p.m. EST on Wednesday the center of Tropical Cyclone Faraji was located at latitude 16.0°S and longitude 84.7°E which put it about 1060 miles (1710 km) southeast of Diego Garcia. Faraji was moving toward the south-southwest at 5 m.p.h. (8 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 960 mb.

After intensification to the equivalent of a Category 5 hurricane on the Saffir-Simpson Scale on Monday, Tropical Cyclone Faraji weakened gradually during the past 48 hours. Even though Faraji weakened, the circulation around the tropical cyclone remained very well organized. A small circular eye was apparent on infrared satellite images. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Storms near the core of the circulation generated upper level divergence which pumped mass away from the tropical cyclone. Winds to hurricane/typhoon force extended out 30 miles (50 km) from the center of circulation. Winds to tropical storm force extended out 130 miles (210 km from the center of Faraji.

Tropical Cyclone Faraji will move into an environment that will become less favorable for a strong tropical cyclone during the next 48 hours. Faraji will move over water where the Sea Surface Temperature is near 28°C. An upper level trough east of Madagascar will move toward Tropical Cyclone Faraji. The approaching trough will produce northwesterly winds which will blow toward the top of the tropical cyclone. Those winds will cause the wind vertical wind shear to increase. More vertical wind shear will likely cause Faraji to weaken during the next 48 hours..

Tropical Cyclone Faraji will move around the northern part of a subtropical high pressure system over the South Indian Ocean. The high will steer Faraji toward the west during the next few days. On its anticipated track Tropical Cyclone Faraji will pass well to the south of Diego Garcia.

Tropical Cyclone Danilo Weakens South of Diego Garcia

Tropical Cyclone Dailo weakened south of Diego Garcia on Wednesday. At 10:00 a.m. EST on Wednesday the center of Tropical Cyclone Danilo was located at latitude 16.6°S and longitude 74.0°E which put it about 665 miles (1070 km) south of Diego Garcia. Danilo was moving toward the west at 9 m.p.h. (15 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.

Northerly winds carried dry air from Asia across the Indian Ocean and some of the dry air was pulled into the circulation around Tropical Cyclone Danilo. The dry air mixed with the moister air in the eyewall and rainbands, which caused the thunderstorms in those regions to weaken. When the thunderstorms weakened, downdrafts that transported stronger winds to the surface also weakened. The eye and eyewall at the center of circulation dissipated. Bands in the northern half of Danilo consisted of showers and lower clouds. Some thunderstorms were still occurring in bands in the southern half of Tropical Cyclone Danilo. Winds to tropical storm force extended out 70 miles (110 km) from the center of circulation.

Tropical Cyclone Danilo will move through an environment somewhat favorable for intensification during the next several days. Danilo will move over water where the Sea Surface Temperature is near 28°C. It will move under an upper level ridge over the South Indian Ocean. The upper level winds are weak under the ridge and there will be little vertical wind shear. If the flow of drier air diminishes, then Tropical Cyclone Danilo could strengthen again. However, if the flow of drier air remains strong, then intensification is unlikely. Slight intensification is forecast during the next 24 hours.

Tropical Cyclone Danilo will move north of a high pressure system over the South Indian Ocean. The ridge will steer Danilo toward the west during the next several days. On its anticipated track Tropical Cyclone Danilo could be north of Rodrigues in 60 hours. Danilo could approach Mauritius and La Reunion in about four days.
