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.

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.

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 minimum surface pressure was 1001 mb.

A low pressure system over the South Indian Ocean north of Rodrigues strengthened on Thursday and Meteo France La Reunion designated the system as Tropical Cyclone Djoungou. The circulation around Djoungou was organizing quickly. The inner end of a rainband wrapped around the eastern and southern sides of the center of Tropical Cyclone Djoungou. Storms near the center of Djoungou’s circulation generated upper level divergence that pumped mass away from the tropical cyclone. Thunderstorms developed in bands in the northern and eastern parts of Tropical Cyclone Djoungou. Bands in the western part of Djoungou’s circulation consisted primarily of showers and lower clouds.

The distribution of wind speeds around Tropical Cyclone Djoungou was asymmetrical. 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 45 miles (75 km) in the southeastern quadrant of Tropical Cyclone Djoungou. The winds in the western half of Djoungou were blowing at less than tropical storm force.

Tropical Cyclone Djoungou will move through an environment very 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 will intensify during the next 24 hours. Djoungou could intensify rapidly at times. 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 during the next 24 hours. On its anticipated track, Tropical Cyclone Djoungou will move farther away from Rodrigues. Djoungou could pass south of Diego Garcia in a few days.

Tropical Cyclone Freddy Still Moving West

Tropical Cyclone Freddy was still moving westward over the South Indian Ocean on Thursday morning. At 10:00 a.m. EST on Thursday the center of Tropical Cyclone Freddy was located at latitude 15.1°S and longitude 78.8°E which put it about 720 miles (1165 km) southeast of Diego Garcia. Freddy was moving toward the west at 17 m.p.h. (28 km/h). The maximum sustained wind speed was 145 m.p.h. (230 km/h) and there were wind gusts to 175 m.p.h. (280 km/h). The minimum surface pressure was 929 mb.

Powerful Tropical Cyclone Freddy continued to move toward the west over the South Indian Ocean. A smallcircular eye with a diameter of 8 miles (13 km) was at the center of Tropical Cyclone Freddy. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Freddy’s circulation. Storms near the core generated strong upper level divergence that pumped mass away from the tropical cyclone in all directions.

The circulation around Tropical Cyclone Freddy was small. Winds to hurricane/typhoon force extended out 50 miles (80 km) from the center of Freddy. Winds to tropical storm force extended out 80 miles (130 km) from the center of circulation. The Hurricane Intensity Index (HII) for Freddy was 30.0. The Hurricane Size Index (HSI) was 14.6 and the Hurricane Wind Intensity Size Index (HWISI) was 44.6.

Tropical Cyclone Freddy will move through an environment that will be favorable for a strong tropical cyclone during the next 24 hours. Freddy will move over over water where the Sea Surface Temperatures are near 28˚C. An upper level ridge over the South Indian Ocean will produce easterly winds that will blow toward the top of Freddy’s circulation. The winds in the lower levels of the atmosphere will also blow from the east. So, there will be little vertical wind shear. If the inner end of a rainband wraps around the existing small inner core of Tropical Cyclone Freddy, then concentric eyewalls could form. That would start an eyewall replacement cycle that would cause Freddy to weaken temporarily.

Tropical Cyclone Freddy will move around the northern part of a high pressure system over the South Indian Ocean. The high pressure system will steer Freddy toward the west during the next several days. On its anticipated track, Tropical Cyclone Freddy will move south of Diego Garcia in 36 hours. Freddy could eventually threaten Mauritius, La Reunion and Madagascar in a few days. Tropical Cyclone Freddy could be northeast of Rodrigues in three days. Freddy could approach Mauritius in four days and it could be near the east coast of Madagascar in five days.

Elsewhere over the South Indian Ocean, Tropical Cyclone Dingani completed a transition to an extratropical cyclone. At 4:00 a.m. EST on Thursday the center of former Tropical Cyclone Dingani was located at latitude 31.5°S and longitude 67.7°E which put it about 860 miles (1385 km) south-southeast of Rodrigues.

Freddy was near the threshold for a Category 5 hurricane on the Saffir-Simpson Scale on Wednesday morning. A circular eye with a diameter of 15 miles (24 km) was at the center of Tropical Cyclone Freddy. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Freddy’s circulation. Storms near the core generated strong upper level divergence that pumped mass away from the tropical cyclone in all directions.

Winds to hurricane/typhoon force extended out 35 miles (55 km) from the center of Tropical Cyclone Freddy. Winds to tropical storm force extended out 125 miles (200 km) from the center of circulation. The Hurricane Intensity Index (HII) for Freddy was 33.3. The Hurricane Size Index (HSI) was 12.4 and the Hurricane Wind Intensity Size Index (HWISI) was 45.7.

Tropical Cyclone Freddy will move through an environment that will be favorable for a strong tropical cyclone during the next 24 hours. Freddy will move over over water where the Sea Surface Temperatures are near 28˚C. An upper level ridge over the South Indian Ocean will produce easterly winds that will blow toward the top of Freddy’s circulation. The winds in the lower levels of the atmosphere will also blow from the east. So, there will be little vertical wind shear. If the inner end of a rainband wraps around the existing eye and eyewall, then concentric eyewalls could forms. That would start an eyewall replacement cycle that would cause Tropical Cyclone Freddy to weaken temporarily.

Tropical Cyclone Freddy will move around the northern part of a high pressure system over the South Indian Ocean. The high pressure system will steer Freddy toward the west during the next few days. On its anticipated track, Tropical Cyclone Freddy will move south of Diego Garcia in three days. Freddy could eventually threaten Mauritius, La Reunion and Madagascar in a few days.

Elsewhere over the South Indian Ocean, Tropical Cyclone Dingani continued to make a transition to an extratropical cyclone. At 4:00 a.m. EST on Wednesday the center of Tropical Cyclone Dingani was located at latitude 27.2°S and longitude 69.2°E which put it about 635 miles (1025 km) southeast of Rodrigues.

Tropical Cyclone Freddy churned westward over the South Indian Ocean on Tuesday. At 10:00 a.m. EST on Tuesday the center of Tropical Cyclone Freddy was located at latitude 15.4°S and longitude 89.3°E which put it about 1315 miles (2120 km) east-southeast of Diego Garcia. Freddy was moving toward the west at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 110 m.p.h. (175 km/h) and there were wind gusts to 130 m.p.h. (210 km/h). The minimum surface pressure was 959 mb.

Tropical Cyclone Freddy started to intensify again when it moved into a more favorable environment on Tuesday morning. A circular eye with a diameter of 25 miles (40 km) was present at the center of Freddy’s circulation. The eye was surrounded by a ring of strong 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 Freddy. Storms near the core generated upper level divergence that pumped mass away from the tropical cyclone.

Winds to hurricane/typhoon force extended out 35 miles (55 km) from the center of Tropical Cyclone Freddy. Winds to tropical storm force extended out 110 miles (175 km) from the center of circulation. The Hurricane Intensity Index (HII) for Freddy was 19.2. The Hurricane Size Index (HSI) was 9.8 and the Hurricane Wind Intensity Size Index (HWISI) was 29.0.

Tropical Cyclone Freddy will move through an environment that will be favorable for intensification during the next 24 hours. Freddy will move over over water where the Sea Surface Temperatures are near 28˚C. An upper level ridge over the Southeast Indian Ocean will produce easterly winds that will blow toward the top of Freddy’s circulation. Those winds will cause some vertical wind shear during the next 24 hours, but the wind shear is not likely to be enough to prevent intensification. Tropical Cyclone Freddy is likely to strengthen back to the equivalent of a major hurricane during the next 24 hours.

Tropical Cyclone Freddy will move around the northern part of a high pressure system over the South Indian Ocean. The high pressure system will steer Freddy toward the west during the next few days. On its anticipated track, Tropical Cyclone Freddy will move south of Diego Garcia in four or five days.

Elsewhere over the South Indian Ocean, Tropical Cyclone Dingani started a transition to an extratropical cyclone. At 4:00 a.m. EST on Tuesday the center of Tropical Cyclone Dingani was located at latitude 22.7°S and longitude 71.5°E which put it about 580 miles (935 km) east-southeast of Rodrigues. Dingani was moving toward the southwest at 10 m.p.h. (16 km/h). The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h).

Tropical Cyclone Freddy Passes South of the Cocos Islands

Tropical Cyclone Freddy passed south of the Cocos Islands on Sunday night. At 10:00 a.m. EST on Monday the center of Tropical Cyclone Freddy was located at latitude 15.4°S and longitude 94.1°E which put it about 275 miles (445 km) south-southwest of Cocos Islands. Freddy was moving toward the west at 14 m.p.h. (22 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 964 mb.

Tropical Cyclone Freddy weakened a little as it passed south of the Cocos Islands on Sunday night. Freddy was moving under the northern part of an upper level ridge over the Southeast Indian Ocean. The ridge produced stronger easterly winds that blew toward the top of Freddy’s circulation during Sunday night. Those winds caused more vertical wind shear and the shear caused Tropical Cyclone Freddy to weaken a little. The wind shear also caused the distribution of thunderstorms in Freddy’s circulation to become more asymmetrical. Many of the thunderstorms were occurring in bands in the western half of Tropical Cyclone Freddy. Some of the bands in the eastern side of Freddy consisted primarily of showers and lower clouds. Winds to hurricane/typhoon force extended out 30 miles (50 km) from the center of Tropical Cyclone Freddy. Winds to tropical storm force extended out 110 miles (175 km) from the center of circulation.

Tropical Cyclone Freddy will move through an environment that will be unfavorable for intensification during the next 24 hours. Freddy will move over over water where the Sea Surface Temperatures are near 27˚C. However, the upper level ridge over the Southeast Indian Ocean will continue to cause moderate vertical wind shear during the next 24 hours. The wind shear is likely to cause Tropical Cyclone Freddy to weaken during the next 24 hours. Freddy could move into a region were the upper level winds are weaker later this week.

Tropical Cyclone Freddy will move around the northern part of a high pressure system over the South Indian Ocean. The high pressure system will steer Freddy toward the west during the next few days. On its anticipated track, Tropical Cyclone Freddy will move farther away from the Cocos Islands. Freddy could be south of Diego Garcia by the end of the week.

Elsewhere over the South Indian Ocean, Tropical Cyclone Dingani was passing east of Rodrigues. At 4:00 a.m. EST on Monday the center of Tropical Cyclone Dingani was located at latitude 19.2°S and longitude 73.2°E which put it about 660 miles (1060 km) east of Rodrigues. Dingani was moving toward the southwest at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 115 m.p.h. (185 km/h). The minimum surface pressure was 969 mb.

Tropical Cyclone Dingani strengthened to the equivalent of a hurricane/typhoon over the South Indian Ocean on Saturday night. At 4:00 a.m. EST on Sunday the center of Tropical Cyclone Dingani was located at latitude 17.0°S and longitude 75.2°E which put it about 810 miles (1310 km) east-northeast of Rodrigues. Dingani was moving toward the west-southwest at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h). The minimum surface pressure was 981 mb.

Tropical Cyclone Dingani strengthened to the equivalent of a hurricane/typhoon on Saturday night. A circular eye with a diameter of 17 miles (28 km) developed at the center of Dingani’s circulation. The eye was surrounded by a ring of strong 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 Dingani. Storms near the core generated upper level divergence that pumped mass away from the tropical cyclone. Winds to hurricane/typhoon force extended out 25 miles (40 km) from the center of Dingani. Winds to tropical storm force extended out 110 miles (175 km) from the center of circulation.

Tropical Cyclone Dingani will move through an environment favorable for intensification during the next 24 hours. Dingani will move over over water where the Sea Surface Temperatures are near 27˚C. It will move under the western part of the axis of an upper level ridge over the South Indian Ocean. The upper level winds are weak near the axis of the ridge. Tropical Cyclone Dingani is likely to intensify during the next 24 hours. Dingani could intensify rapidly at times, since it now has a well developed inner core with an eye and an eyewall.

Tropical Cyclone Dingani will move around the northwestern part of a high pressure system over the South Indian Ocean. The high pressure system will steer Dingani toward the southwest during the next 24 hours. On its anticipated track, Tropical Cyclone Dingani could pass east of Rodrigues early next week.
