Tropical Cyclone Indusa Passes East of Rodrigues

Tropical Cyclone Indusa passed east of Rodrigues on Saturday.  At 5:00 p.m. EDT on Saturday the center of Tropical Cyclone Indusa was located at latitude 24.7°S and longitude 70.4°E which put the center about 575 miles (930 km) east-southeast of Port Mathurin, Rodrigues.  Indusa was moving toward the south at 23 m.p.h. (37 km/h).  The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 982 mb.

Tropical Cyclone Indusa strengthened on Saturday as it passed well to the east of Rodrigues.  Thunderstorms continued to form near the center of Indusa’s circulation.  Bands of showers and thunderstorms were revolving around the center of Tropical Cyclone Indusa.  Storms near the center of Indusa generated upper level divergence that pumped mass away from the tropical cyclone.  The removal of mass caused the surface pressure to decrease.

The distribution of wind speeds around Tropical Cyclone Indusa became a little more asymmetrical on Saturday.  Winds to hurricane/typhoon force extended out 25 miles (40 km) from the center of Indusa’s circulation.  Winds to tropical storm force extended out 100 miles (160 km) in the eastern side of Tropical Cyclone Indusa.  Winds to tropical storm force extended out 60 miles (95 km) in the western half of Indusa’s circulation.

Tropical Cyclone Indusa will move into an environment that will become unfavorable for intensification during the next 24 hours.  Indusa will move over water where the Sea Surface Temperatures are near 24°C.  It will move under the eastern part of an upper level trough that is southeast of Madagascar.  The upper level trough will produce northwesterly winds that will blow toward the top of Indusa’s circulation.  Those winds will cause the vertical wind shear to increase.  Cooler Sea Surface Temperatures and more vertical wind shear will cause Tropical Cyclone Indusa to weaken on Sunday.

The upper level trough that is southeast of Madagascar will steer Tropical Cyclone Indusa toward the south-southeast during the next 24 hours.  On its anticipated track, Tropical Cyclone Indusa will move rapidly farther away from Rodrigues.

Tropical Cyclone Maila Forms Over the Solomon Sea

Tropical Cyclone Maila formed over the Solomon Sea on Saturday.  At 11:00 a.m. EDT on Saturday the center of Tropical Cyclone Maila was located at latitude 8.9°S and longitude 155.0°E which put the center about 515 miles (830 km) east of Port Moresby, Papua New Guinea.  Maila was moving toward the north-northeast at 3 m.p.h. (5 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 990 mb.

A low pressure system over the Solomon Sea strengthened on Saturday and the system was designated as Tropical Cyclone Maila.

Tropical Cyclone Maila was intensifying on Saturday.  More thunderstorms formed near the center of Maila’s circulation.  More thunderstorms also developed in bands revolving around the center of Tropical Cyclone Maila.  Storms near the center of Maila generated upper level divergence that pumped mass away from the tropical cyclone.  The removal of mass caused the surface pressure to decrease.

The distribution of wind speeds around Tropical Cyclone Maila was asymmetrical.  Winds to tropical storm force extended out 150 miles (240 km) in the northern side of Maila’s circulation.  Winds to tropical storm force extended out 80 miles (130 km) in the southern half of Tropical Cyclone Maila.

Tropical Cyclone Maila will be in an environment that will be favorable for intensification during the next 24 hours.  Maila will be over water where the Sea Surface Temperatures are near 30°C.  It will be under the northwestern part of an upper level ridge that is over the Solomons.  The upper level ridge will produce easterly winds that will blow toward the top of Maila’s circulation.  Those winds will cause some vertical wind shear.  The vertical wind shear will inhibit intensification, but the wind shear will not be enough to prevent intensification.  Tropical Cyclone Maila will intensify during the next 24 hours.  Maila is likely to strengthen to the equivalent of a hurricane/typhoon.

Tropical Cyclone Maila will be in a region where the steering winds are weak during the next 24 hours.  Tropical Cyclone Maila is forecast to meander over the Solomon Sea because the steering winds are weak.

Tropical Cyclone Indusa Strengthens to Equivalent of a Hurricane/Typhoon

Tropical Cyclone Indusa strengthened to the equivalent of a hurricane/typhoon over the South Indian Ocean east of Rodrigues on Friday.  At 5:00 p.m. EDT on Friday the center of Tropical Cyclone Indusa was located at latitude 18.5°S and longitude 71.3°E which put the center about 535 miles (655 km) east of Port Mathurin, Rodrigues.  Indusa was moving toward the south-southwest at 16 m.p.h. (26 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 987 mb.

Tropical Cyclone Indusa strengthened to the equivalent of a hurricane/typhoon on Friday.  the inner end of a rainband wrapped around the center of Indusa’s circulation.  Some satellite images showed indications that a small circular eye could be forming at the center of Tropical Cyclone Indusa.  Bands of showers and thunderstorms were revolving around the center of Indusa’s circulation.  Storms near the center of Indusa generated upper level divergence that pumped mass away from the tropical cyclone.  The removal of mass caused the surface pressure to decrease.

The strongest winds were occurring in the eastern side of Tropical Cyclone Indusa.  Winds to hurricane/typhoon force extended out 30 miles (50 km) in the eastern half of Indusa’s circulation.  The circulation around Tropical Cyclone Indusa continued to be small.  Winds to tropical storm force extended out 90 miles (145 km) from the center of Indusa’s circulation.

Tropical Cyclone Indusa will move through an environment that will be favorable for intensification during the next 24 hours. Indusa will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the western part of an upper level ridge that is over the South Indian Ocean.  The upper level ridge will produce northerly winds that will blow toward the top of Indusa’s circulation.  Those winds will cause some vertical wind shear, but the wind shear may not be enough to prevent intensification.  Tropical Cyclone Indusa could continue to intensify during the next 24 hours.  Indusa is likely to start to weaken when it moves over colder water later in the weekend.

Tropical Cyclone Indusa will move around the western end of a high pressure system that is over the South Indian Ocean.  The high pressure system will steer Indusa toward the south during the next 24 hours.  On its anticipated track, Tropical Cyclone Indusa will move farther away from Rodrigues on Saturday.

Tropical Cyclone Indusa Forms South Of Diego Garcia

Tropical Cyclone Indusa formed over the South Indian Ocean south of Diego Garcia on Wednesday night.  At 5:00 a.m. EDT on Thursday the center of Tropical Cyclone Indusa was located at latitude 12.3°S and longitude 73.4°E which put the center about 345 miles (555 km) south of Diego, Garcia.  Indusa was moving toward the south-southwest at 5 m.p.h. (8 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 999 mb.

A low pressure system over the South Indian Ocean south of Diego Garcia strengthened on Wednesday night and Meteo France La Reunion designated the system as Tropical Cyclone Indusa.

More thunderstorms were forming near the center of Tropical Cyclone Indusa on Thursday morning.  Thunderstorms were also developing in bands revolving around the center of Indusa’s circulation.  Storms near the center of Indusa generated upper level divergence that pumped mass away from the tropical cyclone.  The removal of mass caused the surface pressure to decrease.

The circulation around Tropical Cyclone Indusa was small.  Winds to tropical storm force extended out 45 miles (75 km) from the center of Indusa’s circulation.

Tropical Cyclone Indusa will move through an environment favorable for intensification during the next 24 hours.  Indusa will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the western part of an upper level ridge that is over the South Indian Ocean.  The upper level ridge will produce northerly winds that will blow toward the top of Indusa’s circulation.  Those winds will cause some vertical wind shear, but the wind shear will not be enough to prevent intensification.  Tropical Cyclone Indusa will intensify during the next 24 hours.  Indusa is likely to strengthen to the equivalent of a hurricane/typhoon on Friday.

Tropical Cyclone Indusa will move around the western end of a high pressure system that is over the South Indian Ocean.  The high pressure system will steer Indusa toward the south during the next 24 hours.  On its anticipated track, Tropical Cyclone Indusa will move farther away from Diego Garcia.
