Tropical Cyclone Horacio Passes South of Diego Garcia

Tropical Cyclone Horacio passed south of Diego Garcia as it moved over the South Indian Ocean on Saturday.  At 4:00 p.m. EST on Saturday the center of Tropical Cyclone Horacio was located at latitude 17.0°S and longitude 71.3°E which put the center about 675 miles (1095 km) south of Diego Garcia.  Horacio was moving toward the west at 13 m.p.h. (21 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 998 mb.

Tropical Cyclone Horacio struggled to intensify on Saturday.  Horatio was under the northern side of an upper level ridge that was over the South Indian Ocean.  The upper level ridge produced easterly winds that blew toward the top of Horacio’s circulation.  Those winds caused moderate vertical wind shear.  The wind shear inhibited intensification.

The easterly winds in the upper levels and the vertical wind shear also affected the distribution of thunderstorms in Tropical Cyclone Horacio.  Thunderstorms were occurring in bands in the western and northern parts of Horacio’s circulation.  Bands in the eastern and southern sides of Tropical Cyclone Horacio consisted primarily of showers and lower clouds.

The vertical wind shear also affected the distribution of wind speeds in Tropical Cyclone Horacio.  Winds to tropical storm force extended out 100 miles (160 km) in the southern half of Horacio’s circulation.  Winds to tropical storm force extended out 60 miles (95 km) in the northern half of Tropical Cyclone Horacio.

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

Tropical Cyclone Horacio will move around the northern part of a high pressure system that is over the South Indian Ocean.  The high pressure system will steer Horatio toward the west-southwest during the next 24 hours.  On its anticipated track, Tropical Cyclone Horacio will move closer to Rodrigues.  Horacio could approach Rodrigues in 36 hours.

Tropical Cyclone Horacio Develops South of Diego Garcia

Tropical Cyclone Horacio developed over the South Indian Ocean south of Diego Garcia on Thursday night.  At 10:00 a.m. EST on Friday the center of Tropical Cyclone Horacio was located at latitude 15.5°S and longitude 75.3°E which put the center about 610 miles (985 km) south-southeast of Diego Garcia.  Horacio was moving toward the south-southwest at 8 m.p.h. (13 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 999 mb.

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

The circulation around Tropical Cyclone Horacio was organizing quickly on Friday morning.  Thunderstorms were forming near the center of Horatio’s circulation.  Thunderstorms were also developing in bands revolving around the center of Tropical Cyclone Horacio.  Storms near the center of Horacio 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 Horacio was fairly large.  Winds to tropical storm force extended out 175 miles (280 km) from the center of Horacio’s circulation.

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

Tropical Cyclone Horacio will move toward the northern part of a high pressure system that is over the South Indian Ocean.  The high pressure system will steer Horacio toward the west-southwest during the next 24 hours.  On its anticipated track, Tropical Cyclone Horacio will move toward Rodrigues.  Horacio could approach Rodrigues in three days.

Tropical Cyclone Dudzai Churns Westward

Tropical Cyclone Dudzai continued to churn westward over the South Indian Ocean on Friday.  At 10:00 p.m. EST on Friday the center of the Tropical Cyclone Dudzai was located at latitude 17.6°S and longitude 68.8°E which put the center about 750 miles (1210 km) south-southwest of Diego Garcia.  Dudzai was moving toward the west-southwest at 8 m.p.h. (13 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 971 mb.

Tropical Cyclone Dudzai weakened as it churned westward over the South Indian Ocean on Friday.  An eye was no longer visible on satellite imagery of Dudzai on Friday evening.  Bands of showers and thunderstorms were still revolving around the center of Dudzai’s circulation.  Storms near the center of Dudzai generated upper level divergence that pumped mass away from the tropical cyclone.  However, the removal of mass in the upper levels was less than the convergence of mass in the lower levels of the atmosphere.  So, the surface pressure increased on Friday.

The size of the circulation around Tropical Cyclone Dudzai increased on Friday even though Dudzai was weakening.  Winds to hurricane/typhoon force extended out 75 miles (120 km) in the southwestern quadrant of Dudzai’s circulation.  Winds to hurricane/typhoon force extended out 35 miles (55 km) in the other quadrants of Tropical Cyclone Dudzai.  Winds to tropical storm force extended out 155 miles (250 km) in the southern half of Dudzai’s circulation.  Winds to tropical storm force extended out 80 miles (130 km) in the northern half of Tropical Cyclone Dudzai.

The Hurricane Intensity Index (HHI) for Tropical Cyclone Dudzai was 17.8,  The Hurricane Size Index (HSI) was 17.0 and the Hurricane Wind Intensity Size Index (HWISI) was 34.8.

Tropical Cyclone Duzai will move through an environment unfavorable for intensification during the next 24 hours.  Dudzai will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the western part of an upper level rdige that is over the South Indian Ocean.  The upper level ridge will produce northeasterly winds that will blow toward the top of Dudzai’s circulation.  Those winds will cause vertical wind shear.  The vertical wind shear will inhibit intensification. Tropical Cyclone Dudzai will continue to weaken on Saturday because of the vertical wind shear.

Tropical Cyclone Dudzai will move around the northern part of a high pressure system over the South Indian Ocean.  The high pressure system will steer Dudzai toward the west-southwest on during the next 24 hours.  On its anticipated track, Tropical Cyclone Dudzai will approach Rodrigues in 36 hours.

Tropical Cyclone Dudzai Intensifies Back to Equivalent of Cat. 4 Hurricane

Tropical Cyclone Dudzai intensified back to the equivalent of a Category 4 hurricane as it moved over the South Indian south of Diego Garcia on Thursday.  At 4:00 p.m. EST on Thursday the center of the Tropical Cyclone Dudzai was located at latitude 16.9°S and longitude 72.4°E which put the center about 675 miles (1090 km) south of Diego Garcia.  Dudzai was moving toward the west 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. (265 km/h).  The minimum surface pressure was 942 mb.

Tropical Cyclone Dudzai rapidly intensified back to the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale on Thursday.  Dudzai started to intensify rapidly after it moved west of cooler water that its winds had mixed to the surface of the ocean earlier this week.  Tropical Cyclone Dudzai was able to extract more energy from the South Indian Ocean, which cause it to intensify rapidly.

A small circular eye was visible again on satellite images at the center of Tropical Cyclone Dudzai.  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 round the core of Dudzai’s circulation.  Storms near the core of Dudzai generated more upper level divergence that pumped more mass away from the tropical cyclone.  The removal of more mass caused the surface pressure to decrease rapidly.

The size of the circulation around Tropical Cyclone Dudzai increased on Thursday.  Winds to hurricane/typhoon force extended out 35 miles (55 km) from the center of Dudzai’s circulation.  Winds to tropical storm force extended out 150 miles (240 km) in the southern half of Tropical Cyclone Dudzai.  Winds to tropical storm force extended out 80 miles (130 km) in the northern side of Dudzai’s circulation.

The Hurricane Intensity Index (HII) for Tropical Cyclone Dudzai was 28.3.  The Hurricane Size Index (HSI) was 13.0 and the Hurricane Wind Intensity Size Index (HWISI) was 41.3.  Tropical Cyclone Dudzai was similar in size and intensity to Hurricane Harvey when Harvey hit Texas in 2017.

Tropical Cyclone Duzai will move through an environment favorable for a strong tropical cyclone during the next 24 hours.  Dudzai will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the northern part of an upper level trough that is over the South Indian Ocean.  The upper level trough will produce westerly winds that will blow toward the top of Dudzai’s circulation.  Those winds will cause some vertical wind shear. The vertical wind shear will inhibit intensification.  Tropical Cyclone Dudzai is likely to start to weaken on Friday because of the vertical wind shear.

Tropical Cyclone Dudzai will move around the northern part of a high pressure system over the South Indian Ocean.  The high pressure system will steer Dudzai toward the west on during the next 24 hours.  On its anticipated track, Tropical Cyclone Dudzai will remain far to the south of Diego Garcia.  Dudzai could approach Rodrigues during the weekend.

Tropical Cyclone Dudzai Moves West

Tropical Cyclone Dudzai moved toward the west over the South Indian Ocean on Wednesday.  At 4:00 p.m. EST on Wednesday the center of the Tropical Cyclone Dudzai was located at latitude 17.2°S and longitude 75.9°E which put the center about 740 miles (1195 km) south-southeast of Diego Garcia.  Dudzai was moving toward the west at 6 m.p.h. (8 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 984 mb.

Tropical Cyclone Dudzai continued to be the equivalent of a hurricane/typhoon as it moved westward over the South Indian Ocean on Wednesday.  Thunderstorms continued to develop near the center of Dudzai’s circulation.  Thunderstorms were also occurring in bands revolving around the center of Tropical Cyclone Dudzai.  Storms near the center of Dudzai generated upper level divergence that pumped mass away from the tropical cyclone.  The removal of mass in the upper levels was nearly equal to the convergence of the mass in the lower levels of the atmosphere.  So, the surface pressure was nearly steady on Wednesday afternoon.

The strongest winds were occurring in the southern half of Tropical Cyclone Dudzai.  Winds to hurricane/typhoon force extended out 25 miles (40 km) in the southern half of Dudzai’s circulation.  Winds to tropical storm force extended out 90 miles (145 km) in the southern side of Tropical Cyclone Dudzai.  Winds to tropical storm force extended out 60 miles in the northern half of Dudzai’s circulation.

Tropical Cyclone Dudzai will move into an environment that will become more favorable for intensification during the next 24 hours.  Tropical Cyclone Dudzai will move farther away from cooler water it mixed to the surface while it moved slowly during the beginning of this week.  Dudzai will move over water where the Sea Surface Temperatures are near 28°C.   It will move under the eastern side of an upper level trough that is over the South Indian Ocean.  The upper level trough will produce northwesterly winds that will blow toward the top of Dudzai’s circulation.  Those winds will cause some vertical wind shear.  The vertical wind shear will inhibit intensification, but the wind shear may not be enough to prevent intensification.  Tropical Cyclone Dudzai is likely to intensify on Thursday.

Tropical Cyclone Dudzai will move around the northern part of a high pressure system over the South Indian Ocean.  The high pressure system will steer Dudzai toward the west on during the next 24 hours.  On its anticipated track, Tropical Cyclone Dudzai will remain far to the south of Diego Garcia.

Tropical Cyclone Dudzai Weakens

Tropical Cyclone Dudzai weakened as it moved over the South Indian Ocean on Tuesday.  At 4:00 p.m. EST on Tuesday the center of the Tropical Cyclone Dudzai was located at latitude 17.2°S and longitude 77.5°E which put the center about 775 miles (1255 km) south-southeast of Diego Garcia.  Dudzai was moving toward the west at 3 m.p.h. (5 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 977 mb.

Tropical Cyclone Dudzai weakened on Tuesday.  Dudzai continued to move slowly over cooler water its winds had mixed to the surface of the ocean.  The cooler water contained less energy.  Tropical Cyclone Dudzai weakened because it was extracting less energy from the ocean.

Even though Tropical Cyclone Dudzai weakened, its structure remained intact.  There was a very small circular eye at the center of Dudzai’s circulation.  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 center of Dudzai’s circulation.  Storms near the center of Dudzai generated upper level divergence that pumped mass away from the tropical cyclone.  However, the removal of mass in the upper levels was less than the convergence of mass in the lower levels of the atmosphere.  So, the surface pressure was increasing.

The circulation around Tropical Cyclone Dudzai was small.  Winds to hurricane/typhoon force extended out 30 miles (50 km) from the center of Dudzai’s circulation.  Winds to tropical storm force extended out 75 miles (120 km) from the center of Tropical Cyclone Dudzai.

The Hurricane Intensity Index (HII) for Tropical Cyclone Dudzai is 13.9.  The Hurricane Size Index (HSI) is 9.8 and the Hurricane Wind Intensity Size Index (HWISI) is 23.7.  Tropical Cyclone Dudzai is similar in size and intensity to Hurricane Hannah when Hannah hit Texas in 2020.

Tropical Cyclone Dudzai will move through an environment that will be unfavorable for intensification during the next 24 hours.  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 northeasterly winds that will blow toward the top of Dudzai’s circulation.  Those winds will cause some vertical wind shear.  The vertical wind shear will inhibit intensification.  In addition, the strong winds in the lower levels of Dudzai’s circulation will continue to mix cooler water to the surface of the South Indian Ocean.  The cooler water will transfer less energy into Tropical Cyclone Dudzai. Tropical Cyclone Dudzai is likely to continue to weaken during the next 24 hours due to the upwelling of cooler water.

Tropical Cyclone Dudzai will move around the northeastern part of a high pressure system over the South Indian Ocean.  The high pressure system will steer Dudzai toward the west on during the next 24 hours.  On its anticipated track, Tropical Cyclone Dudzai will remain far to the south of Diego Garcia.

Tropical Cyclone Dudzai Strengthens to Equivalent of Cat. 4 Hurricane

Tropical Cyclone Dudzai strengthened to the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale on Monday.  At 4:00 p.m. EST on Monday the center of the Tropical Cyclone Dudzai was located at latitude 17.1°S and longitude 78.0°E which put the center about 775 miles (1255 km) south-southeast of Diego Garcia.  Dudzai was moving toward the south-southeast at 3 m.p.h. (5 km/h).  The maximum sustained wind speed was 130 m.p.h. (210 km/h) and there were wind gusts to 160 m.p.h. (260 km/h).  The minimum surface pressure was 948 mb.

Tropical Cyclone Dudzai continued to intensify on Monday afternoon.  Dudzai strengthened to the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale.  A small circular eye was present at the center of Tropical Cyclone Dudzai.  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 Dudzai’s circulation.  Storms near the core of Dudzai generated upper level divergence that pumped mass away from the tropical cyclone.  The removal of mass caused the surface pressure to continue to decrease.

The Hurricane Intensity Index (HII) for Tropical Cyclone Dudzai is 25.1.  The Hurricane Size Index (HSI) is 10.5 and the Hurricane Wind Intensity Size Index (HWISI) is 35.6.  Tropical Cyclone Dudzai is similar in intensity to Hurricane Harvey when Harvey hit Texas in 2017.  Dudzai is slightly smaller than Harvey was.

Tropical Cyclone Dudzai will move through an environment that will become less favorable for intensification during the next 24 hours.  It will move under the middle of an upper level ridge that is over the South Indian Ocean.  The upper level winds are weak in the middle of the ridge and there will be little vertical wind shear.  However, the strong winds in the lower levels of Dudzai’s circulation will mix cooler water to the surface of the South Indian Ocean.  The cooler water will transfer less energy into Tropical Cyclone Dudzai.  Tropical Cyclone Dudzai is likely to weaken during the next 24 hours due to the upwelling of cooler water.

Tropical Cyclone Dudzai will move through a region where the steering winds are weak during the next 12 hours.  Dudzai is likely to move slowly toward the south during that time period.  A high pressure system that is southwest of Dudzai will start to steer it toward the west on Wednesday.  On its anticipated track, Tropical Cyclone Dudzai will remain far to the south of Diego Garcia.
