Tropical Cyclone Eleanor Forms North of Mauritius

Tropical Cyclone Eleanor formed over the South Indian Ocean north of Mauritius on Monday. At 1:00 p.m. EST on Monday the center of Tropical Cyclone Eleanor was located at latitude 14.1°S and longitude 56.6°E which put it about 415 miles (670 km) north of Port Louis, Mauritius. Eleanor was moving toward the east at 13 m.p.h. (21 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 999 mb.

A low pressure system over the South Indian Ocean north of Mauritius strengthened on Monday and Meteo France La Reunion designated the system as Tropical Cyclone Eleanor. More thunderstorms formed near the center of Eleanor’s circulation. Bands of showers and thunderstorms were revolving around the center of Tropical Cyclone Eleanor. Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical cyclone. Winds to tropical storm force extended out 150 miles (240 km) from the center of Eleanor’s circulation.

Tropical Cyclone Eleanor will move through an environment favorable for intensification during the next 36 hours. Eleanor will move over water where the Sea Surface Temperatures are near 29°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 Eleanor will intensify during the next 36 hours. Eleanor could intensify rapidly at times. Tropical Cyclone Eleanor is likely to strengthen to the equivalent of a hurricane/typhoon.

Tropical Cyclone Eleanor will move around the western end of a high pressure system over the South Indian Ocean. The high pressure system will steer Eleanor toward the south during the next 48 hours. On its anticipated track, the center of Tropical Cyclone Eleanor will approach Mauritius in 48 hours. Eleanor is likely to be the equivalent of a hurricane/typhoon when it approaches Mauritius.

Elsewhere over the South Indian Ocean, Tropical Cyclone Djoungou weakened rapidly west of Australia. At 4:00 p.m. EST on Monday the center of Tropical Cyclone Djoungou was located at latitude 30.7°S and longitude 93.9°E which put it about 1470 miles (2370 km) west of Perth, Australia. Djoungou was moving toward the southeast at 47 m.p.h. (76 km/h). The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h). The minimum surface pressure was 984 mb.

Tropical Cyclone Djoungou Strengthens to Equivalent of Cat. 4 Hurricane

Tropical Cyclone Djoungou strengthened to the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale over the South Indian Ocean on Sunday. At 4:00 p.m. EST on Sunday the center of Tropical Cyclone Djoungou was located at latitude 22.5°S and longitude 82.3°E which put it about 1150 miles (1855 km) south-southeast of Diego Garcia. Djoungou was moving toward the southeast at 33 m.p.h. (54 km/h). The maximum sustained wind speed was 140 m.p.h. (220 km/h) and there were wind gusts to 165 m.p.h. (265 km/h). The minimum surface pressure was 942 mb.

A small circular was visible at the center of Tropical Cyclone Djoungou earlier on Sunday, but the eye was no longer evident on Sunday afternoon. 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 core of Tropical Cyclone Djoungou. Storms near the core generated strong upper level divergence that pumped lmass away from the tropical cyclone.

The size of the circulation around Tropical Cyclone Djoungou increased on Sunday. Winds to hurricane/typhoon force extended out 70 miles (110 km) from the center of Djoungou’s circulation. Winds to tropical storm force extended out 200 miles (320 km) from the center of circulation. The Hurricane Intensity Index (HII) for Tropical Cyclone Djoungou was 28.2. The Hurricane Size Index (HSI) was 25.7 and the Hurricane Wind Intensity Size Index (HWISI) was 53.9.

Tropical Cyclone Djoungou will move through an environment unfavorable for a strong tropical cyclone during the next 36 hours. Djoungou will move over water where the Sea Surface Temperatures are near 26°C. It will move under the eastern part of an upper level trough over the South Indian Ocean. The upper level trough will produce strong northwesterly winds that will blow toward the top of Djoungou’s circulation. Those winds will cause strong vertical wind shear. Strong vertical wind shear and cooler water will cause Tropical Cyclone Djoungou to weaken rapidly during the next 36 hours.

Tropical Cyclone Djoungou will move around the southern side of a high pressure system over the South Indian Ocean. The high pressure system will steer Djoungou toward the east-southeast during the next 36 hours. On its anticipated track, Tropical Cyclone Djoungou will move far to the south of the Cocos Islands in 36 hours.

Elsewhere over the South Indian Ocean, a tropical depression formed northwest of Mauritius. At 1:00 p.m. EST on Sunday the center of the tropical depression was located at latitude 15.5°S and longitude 5363°E which put it about 405 miles (650 km) northwest of Port Louis, Mauritius. The tropical depression was moving toward the east-northeast at 11 m.p.h. (17 km/h). The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h). The minimum surface pressure was 1004 mb.

Tropical Cyclone Djoungou Rapidly Intensifies to Equivalent of a Major Hurricane

Tropical Cyclone Djoungou rapidly intensified to the equivalent of a major hurricane over the South Indian Ocean south of Diego Garcia on Saturday. At 4:00 p.m. EST on Saturday the center of Tropical Cyclone Djoungou was located at latitude 17.1°S and longitude 73.3°E which put it about 660 miles (1065 km) south of Diego Garcia. Djoungou was moving toward the east-southeast at 22 m.p.h. (35 km/h). The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 145 m.p.h. (235 km/h). The minimum surface pressure was 960 mb.

A small circular eye formed at the center of Tropical Cyclone Djoungou as it rapidly intensified on Saturday. 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 core of Tropical Cyclone Djoungou. Storms near the core generated strong upper level divergence that pumped large quantities of mass away from the tropical cyclone. The removal of large amounts of mass caused the surface pressure to decrease rapidly.

The circulation around Tropical Cyclone Djoungou also became more symmetrical when Djoungou rapidly intensified. Winds to hurricane/typhoon force extended out 50 miles (80 km) from the center of Djoungou’s circulation. Winds to tropical storm force extended out 185 miles (295 km) from the center of circulation. The Hurricane Intensity Index (HII) for Tropical Cyclone Djoungou was 20.6. The Hurricane Size Index (HSI) was 20.2 and the Hurricane Wind Intensity Size Index (HWISI) was 40.8.

Tropical Cyclone Djoungou will move through an environment favorable for intensification during the next 24 hours. Djoungou will move over water where the Sea Surface Temperatures are near 29°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 Djoungou is likely to intensify during the next 24 hours. However, Djoungou could start to weaken if the inner end of a rainband wraps around the existing eye and eyewall and concentric eyewalls form.

Tropical Cyclone Djoungou will move around the southern side of a high pressure system over the South Indian Ocean. The high pressure system will steer Djoungou toward the east-southeast during the next 24 hours. On its anticipated track, Tropical Cyclone Djoungou will move farther southeast of Diego Garcia.

The minimum surface pressure was 988 mb.

Tropical Cyclone Djoungou intensified rapidly over the South Indian Ocean on Friday. The inner end of a rainband wrapped around the center of Djoungou’s circulation. A small eye was visible intermittently at the center of Tropical Cyclone Djoungou. The developing 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 core of Djoungou. Storms near the core generated upper level divergence that pumped mass away from the tropical cyclone. The removal of mass caused the surface pressure to decrease.

Winds to hurricane/typhoon force extended out 45 miles (75 km) from the center of Tropical Cyclone Djoungou. Winds to tropical storm force extended out 175 miles (280 km) in the northeastern quadrant of Djoungou’s circulation. Winds to tropical storm force extended out 80 miles (130 km) in the other parts of Tropical Cyclone Djoungou.

Tropical Cyclone Djoungou will move through an environment very favorable for intensification during the next 36 hours. Djoungou will move over water where the Sea Surface Temperatures are near 29°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 Djoungou will intensify during the next 36 hours. Djoungou could intensify more rapidly once the eye and eyewall are fully formed. Tropical Cyclone Djoungou could strengthen to the equivalent of a major hurricane during the weekend.

Tropical Cyclone Djoungou will move around the southern side of a high pressure system over the South Indian Ocean. The high pressure system will steer Djoungou toward the east-southeast during the next 36 hours. On its anticipated track, Tropical Cyclone Djoungou will pass south of Diego Garcia in 24 hours.
