Tropical Cyclone Forms North-Northeast of Mauritius

Tropical Cyclone 12S formed north-northeast of Mauritius on Sunday morning. At 5:00 a.m. EST on Sunday the center of Tropical Cyclone 12S was located at latitude 15.1°S and longitude 60.5°E which put it about 430 miles (695 km) north-northeast of Port Louis, Mauritius. The tropical cyclone was moving toward the west-southwest at 8 m.p.h. (13 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 998 mb.

Tropical Cyclone 12S formed over the Southwest Indian Ocean early on Sunday morning. The distribution of thunderstorms around Tropical Cyclone 12S was asymmetrical. The strongest thunderstorms were occurring southeast of the center of circulation. Bands in other parts of the tropical cyclone consisted primarily of showers and lower clouds. Storms near the center of circulation began to generate upper level divergence that pumped mass away from the tropical cyclone. The circulation around Tropical Cyclone 12S was small. Winds to tropical storm force extended out 30 miles (50 km) in the southeastern quadrant of the tropical cyclone. The winds in the other parts of Tropical Cyclone 12S were blowing at less than tropical storm force.

Tropical Cyclone 12S will move through an environment somewhat favorable for intensification during the next 24 hours. Tropical Cyclone 12S will move over water where the Sea Surface Temperatures are near 28˚C. It will move under the axis of an upper level ridge over the Southwest Indian Ocean. The upper level winds are weak bear the axis of the ridge and there will be little vertical wind shear. There is drier air to the north of Tropical Cyclone 12S. Drier air could inhibit the formation of thunderstorms in the northern part of the tropical cyclone’s circulation. If drier air inhibits the formation of thunderstorms, then it could prevent intensification of Tropical Cyclone 12S. Since the circulation around Tropical Cyclone 12S is small, changes in the environment could have big effects on the circulation. Tropical Cyclone 12S could get a little stronger during the next 24 hours.

Tropical Cyclone 12S will move north of a subtropical high pressure system over the Southwest Indian Ocean. The high pressure system will steer the tropical cyclone toward the west-southwest during the next several days. On its anticipated track Tropical Cyclone 12S will pass north of Mauritius in 24 hours. The small size of the circulation means that the tropical cyclone should have little effect on Mauritius. Tropical Cyclone 12S could be north of La Reunion in 36 hours. The tropical cyclone could reach northern Madagascar in less than three days.

Tropical Cyclone Batsirai Brings Wind and Rain to Mauritius

Tropical Cyclone Batsirai brought wind and rain to Mauritius on Wednesday. At 10:00 a.m. EST on Wednesday the center of Tropical Cyclone Batsirai was located at latitude 19.0°S and longitude 56.3°E which put it about 90 miles (145 km) north-northwest of Port Louis, Mauritius. Batsirai was moving toward the west-southwest at 11 m.p.h. (17 km/h). The maximum sustained wind speed was 145 m.p.h. (235 km/h) and there were wind gusts to 175 m.p.h. (280 km/h). The minimum surface pressure was 931 mb.

The core of Tropical Cyclone Batsirai passed north of Mauritius on Wednesday, but it still brought wind and rain. A weather station at Champ de Mars, near Port Louis, reported a wind speed of 94 m.p.h. (151 km/h). Another weather station near Port Louis at Bell Village reported 6.01 inches (152.7 mm) of rain.

Tropical Cyclone Batsirai appeared to undergo an eyewall replacement cycle. The tiny inner eyewall dissipated and a new larger eye was apparent on satellite images. Batsirai may have been near Category 5 on the Saffir-Simpson Scale before the inner eyewall dissipated. The new 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 Batsirai. Storms near the core generated strong upper level divergence that pumped large quantities of mass away from the tropical cyclone.

The size of the circulation around Tropical Cyclone Batsirai increased during the eyewall replacement cyclone. Winds to hurricane/typhoon force extended out 65 miles (105 km) from the center of Batsirai. Winds to tropical storm force extended out 215 miles (345 km) from the center of circulation. The Hurricane Intensity Index (HII) for Tropical Cyclone Batsirai was 29.9. The Hurricane Size Index (HSI) was 23.1 and the Hurricane Wind Intensity Size Index (HWISI) was 53.0.

Tropical Cyclone Batsirai will move through an environment capable of supporting a strong tropical cyclone during the next 36 hours. Batsirai will move over water where the Sea Surface Temperatures are near 29˚C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Tropical Cyclone Batsirai weakened after the eyewall replacement cycle, but it could strengthen again since the inner core is still intact. There is a chance that Batsirai could reach Category 5 on the Saffir-Simpson Scale.

Tropical Cyclone Batsirai will move north of a high pressure system over the South Indian Ocean. The high pressure system will steer Batsirai toward the west-southwest during the next several days. Weather conditions on Mauritius will improve gradually as Batsirai moves farther away. On its anticipated track the center of Tropical Cyclone Batsirai will pass north of La Reunion during the next 24 hours. Although the strongest winds in Batsirai will pass north of La Reunion, it could experience strong winds and locally heavy rain. Locally heavy rain could cause flash floods in some locations. Tropical Cyclone Batsirai could reach the east coast of Madagascar within 60 hours. Batsirai is likely to be the equivalent of a major hurricane when it reaches Madagascar.

Tropical Cyclone Batsirai Rapidly Intensifies to Equivalent of a Major Hurricane

Tropical Cyclone Batsirai rapidly intensified to the equivalent of a major hurricane on Tuesday night. At 10:00 p.m. EST on Tuesday the center of Tropical Cyclone Batsirai was located at latitude 18.3°S and longitude 57.9°E which put it about 155 miles (250 km) northeast of Port Louis, Mauritius. Batsirai was moving toward the southwest at 11 m.p.h. (17 km/h). The maximum sustained wind speed was 140 m.p.h. (225 km/h) and there were wind gusts to 165 m.p.h. (270 km/h). The minimum surface pressure was 915 mb.

Tropical Cyclone Batsirai rapidly intensified to the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale on Tuesday night. The core of Batsirai contracted around a tiny pinhole eye. 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 Batsirai. Storms near the core generated strong upper level divergence that large quantities of mass away from the tropical cyclone. The removal of that much mass allowed the surface pressure to decrease rapidly.

Tropical Cyclone Batsirai increased in size as it intensified rapidly. Winds to hurricane/typhoon force extended out 45 miles (75 km) from the center of Batsirai. Winds to tropical storm force extended out 195 miles (315 km) from the center of circulation. The Hurricane Intensity Index (HII) for Tropical Cyclone Batsirai was 28.3. The Hurricane Size Index (HSI) was 18.3 and the Hurricane Wind Intensity Size Index (HWISI) was 46.6.

Tropical Cyclone Batsirai will move through an environment capable of supporting a strong tropical cyclone during the next 48 hours. Batsirai will move over water where the Sea Surface Temperatures are near 29˚C. It will move under the northern part of an upper level ridge over the Southwest Indian Ocean. The ridge will produced easterly winds that will blow toward the top of Batsirai’s circulation. Those winds will cause some vertical wind shear and the wind shear could inhibit additional intensification. If the inner end of a rainband wraps around the existing eye and eyewall, then an eyewall replacement cycle could begin. If an eyewall replacement cycle occurs Tropical Cyclone Batsirai is likely to weaken, at least temporarily.

Tropical Cyclone Batsirai will move north of a high pressure system over the South Indian Ocean. The high pressure system will steer Batsirai toward the west-southwest during the next several days. On its anticipated track the center of Tropical Cyclone Batsirai will pass north of Mauritius during the next 12 hours. Although the strongest winds in Batsirai will pass north of Mauritius, it could experience tropical storm force winds and locally heavy rain. Locally heavy rain could cause flash floods in some locations. Tropical Cyclone Batsirai will be north of La Reunion in 24 hours. Batsirai could reach the east coast of Madagascar within 72 hours. Tropical Cyclone Batsirai could still be the equivalent of a major hurricane when it reaches Madagascar.

Tropical Cyclone Forecast to Develop, Hit Northern Madagascar

A tropical cyclone is forecast to develop over the South Indian Ocean and to hit northern Madagascar during the weekend. The system is currently a low pressure system designated as Invest 93S. At 7:00 a.m. EST on Thursday the center of Invest 93S was located at latitude 14.9°S and longitude 59.0°E which put it about 435 miles (700 km) north-northeast of Mauritius. It was moving toward the west at 5 m.p.h. (8 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. (60 km/h). The minimum surface pressure was 1006 mb.

A low pressure system, currently designated as Invest 93S, over the South Indian Ocean north-northeast of Mauritius is forecast to move west toward northern Madagascar and to develop into a tropical cyclone during the next 72 hours. The distribution of thunderstorms around the low pressure system is currently asymmetrical. The strongest thunderstorms are occurring in bands in the western side of the low pressure system. Bands in the eastern half of the circulation consist primarily of showers and lower clouds. Storms in the western half of the system generated upper level divergence that pumped mass away to the west of the low pressure system.

Invest 93S will move through an environment favorable for the development of a tropical cyclone during the next 48 hours. The low pressure system will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the northwestern part of an upper level ridge over the South Indian Ocean. The ridge will produce easterly winds that will blow toward the top of the circulation. Those winds will cause moderate vertical wind shear. The wind shear is currently contributing to the asymmetrical distribution of thunderstorms. However, the vertical wind shear will not be strong enough to prevent Invest 93S from developing into a tropical cyclone.

Invest 93S will move around the northern side of a high pressure system over the South Indian Ocean. The high pressure system will steer the low pressure system toward the west-southwest during the next 48 hours. On its anticipated track Invest 93S could reach the coast of northeastern Madagascar within 72 hours. Invest 93S is forecast to be a tropical cyclone when it reaches northern Madagascar. It will bring strong winds and locally heavy rain to northern Madagascar during the weekend. Locally heavy rain could cause flash floods in some locations.

Tropical Cyclone Iman Brings Rain to La Reunion

Tropical Cyclone Iman brought rain to La Reunion and Mauritius on Saturday night. At 7:00 p.m. EST on Saturday the center of Tropical Cyclone Iman was located at latitude 22.6°S and longitude 54.5°E which put it about 105 miles (165 km) south-southwest of La Reunion. Iman was moving toward the east-southeast at 23 m.p.h. (37 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.

An area of low pressure strengthened on Saturday after it moved over the South Indian Ocean east of Madagascar and Meteo France la Reunion designate the system as Tropical Cyclone Iman. The distribution of thunderstorms around Tropical Cyclone Iman was asymmetrical. The strongest thunderstorms were occurring in bands in the eastern half of Iman. Bands in the western half of the tropical cyclone consisted of primarily of showers and thunderstorms. Storms east of the center of circulation generated upper level divergence which pumped mass away to the southeast of the tropical cyclone.

Rainbands on the eastern side of Tropical Cyclone Iman brought gusty winds and locally heavy rain to La Reunion and Mauritius. Heavy rain could cause flash floods in some locations, especially in areas of steeper terrain.

An upper level trough south of Madagascar will steer Tropical Cyclone Iman toward the east-southeast. On its anticipated track Tropical Cyclone Iman will move quickly away to the southeast of La Reunion and Mauritius. Weather conditions in those locations will improve on Sunday.

Tropical Cyclone Iman will move into an environment that will be marginally favorable for intensification during the next 24 hours. Iman will move over water where the Sea Surface Temperatures will be near 27°C. The upper level trough will produce northwesterly winds which will blow toward the top of Iman. Those winds will cause more vertical wind shear and they will inhibit intensification.

Elsewhere over the South Indian Ocean, powerful Tropical Cyclone Habana maintained its intensity south-southeast of Diego Garcia. At 4:00 p.m. EST on Saturday the center of Tropical Cyclone Habana was located at latitude 16.8°S and longitude 79.2°E which put it about 785 miles (1265 km) south-southeast of Diego Garcia.
