Tropical Cyclone Honde Lingers Near Southern Madagascar

Tropical Cyclone Honde lingered near southern Madagascar on Sunday.  At 4:00 a.m. EST on Sunday the center of Tropical Cyclone Honde was located at latitude 27.1°S and longitude 46.1°E which put the center about 195 miles (315 km) south of Ambovombe, Madagascar.  Honde was moving toward the southeast at 2 m.p.h. (3 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 975 mb.

Tropical Cyclone Honde was the equivalent of a hurricane/typhoon as it lingered near southern Madagascar on Sunday.  A circular eye with a diameter of 20 miles (32 km) was at the center of Honde’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 Tropical Cyclone Honde.  Storms near the center of Honde generated upper level divergence that pumped mass away from the tropical cyclone.  The divergence of mass in the upper levels of the atmosphere was almost balanced by the inflow of mass in the lower levels of Tropical Cyclone Honde.  As a result, the surface pressure was not changing much.

The size of the circulation around Tropical Cyclone Honde was smaller on Sunday.  Winds to hurricane/typhoon force extended out 40 miles (65 km) in the southern half of Honde’s circulation.  Winds to tropical storm force extended out 140 miles (220 km) from the center of Tropical Cyclone Honde.

Tropical Cyclone Honde will move through an environment that will become less favorable for intensification during the next 24 hours.  Honde will move over water where where the Sea Surface Temperatures are near 27°C.  It will move under the eastern side of an upper level trough near southern Africa.  The upper level trough will produce northwesterly winds that will blow toward the top of Honde’s circulation.  Those winds will cause moderate vertical wind shear.  The moderate vertical wind shear will inhibit intensification.  Tropical Cyclone Honde will likely maintain its intensity during the next 24 hours.

The upper level trough near southern Africa will steer Tropical Cyclone Honde toward the southeast during the next 24 hours.  On its anticipated track, the center of Tropical Cyclone Honde will gradually move farther away from southern Madagascar.

Bands in the northern side of Tropical Cyclone Honde will continue to bring gusty winds and locally heavy rain to parts of southern Madagascar during the next 24 hours.  Additional heavy rain will likely cause flash floods in some locations.

Elsewhere over the Southwest Indian Ocean, Tropical Cyclone Garance was making a transformation to and extratropical cyclone far to the south of La Reunion.  At 4:00 a.m. EST on Sunday the center of Tropical Cyclone Garance was located at latitude 33.8°S and longitude 59.9°E which put the center about 925 miles (1495 km) south-southeast of St. Denis, La, Reunion.  Garance was moving toward the southeast at 25 m.p.h. (40 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 993 mb.

Tropical Cyclone Honde Brings Wind and Rain to Southern Madagascar

Tropical Cyclone Honde continued to bring wind and rain to southern Madagascar on Saturday.  At 4:00 a.m. EST on Saturday the center of Tropical Cyclone Honde was located at latitude 26.9°S and longitude 45.3°E which put the center about 120 miles (195 km) south of Tsiombe, Madagascar.  Honde was moving toward the southeast at 4 m.p.h. (6 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 970 mb.

Bands in the northern side of Tropical Cyclone Honde continued to bring strong winds and locally heavy rain to parts of southern Madagascar on Saturday.  A circular eye with a diameter of 24 miles (38 km) was at the center of Honde’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 Tropical Cyclone Honde.  Storms near the center of Honde generated upper level divergence that pumped mass away from the tropical cyclone.  The divergence of mass in the upper levels of the atmosphere was almost balanced by the inflow of mass in the lower levels of Tropical Cyclone Honde.  As a result, the surface pressure was not changing much.

The circulation around Tropical Cyclone Honde was large.  Winds to hurricane/typhoon force extended out 40 miles (65 km) in the southern half of Honde’s circulation.  Winds to tropical storm force extended out 220 miles (350 km) from the center of Tropical Cyclone Honde.

The Hurricane Intensity Index (HII) for Tropical Cyclone Honde was 10.4.  The Hurricane Size Index (HSI) was 12.5 and the Hurricane Wind Intensity Size Index (HWISI) was 22.9.  Tropical Cyclone Honde was similar in intensity to Hurricane Dolly when Dolly hit south Texas in 2008.

Tropical Cyclone Honde will move through an environment marginally favorable for intensification during the next 24 hours.  Honde will move over water where where the Sea Surface Temperatures are near 27°C.  It will move under the eastern side of an upper level trough near southern Africa.  The upper level trough will produce northwesterly winds that will blow toward the top of Honde’s circulation.  Those winds will cause moderate vertical wind shear.  The moderate vertical wind shear will inhibit intensification. Tropical Cyclone Honde will likely maintain its intensity during the next 24 hours.

The upper level trough near southern Africa will steer Tropical Cyclone Honde slowly toward the southeast during the next 24 hours.  On its anticipated track, the center of Tropical Cyclone Honde will move a little farther away from southern Madagascar.

Tropical Cyclone Honde will continue to bring strong winds and locally heavy rain to parts of southern Madagascar during the next 24 hours.  Prolonged heavy rain will likely cause flash floods in some locations.

Elsewhere over the Southwest Indian Ocean, Tropical Cyclone Garance was weakening as it moved farther to the south of La Reunion.  At 4:00 a.m. EST on Saturday the center of Tropical Cyclone Garance was located at latitude 28.6°S and longitude 55.0°E which put the center about 505 miles (815 km) south of St. Denis, La, Reunion.  Garance was moving toward the south at 21 m.p.h. (33 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 986 mb.

Tropical Cyclone Garance Batters La Reunion

Tropical Cyclone Garance battered La Reunion on Friday.  At 4:00 a.m. EST on Friday the center of Tropical Cyclone Garance was located at latitude 21.8°S and longitude 55.4°E which put the center about 35 miles (55 km) south-southeast of St. Denis, La, Reunion.  Garance was moving toward the south at 15 m.p.h. (24 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 962 mb.

The core of Tropical Cyclone Garance moved directly over La Reunion on Friday.  Roland Garros airport (FMEE) measured a sustained wind speed of 61 knots (70 m.p.h. or 113 km/h) and a wind gust of 83 knots (95 m.p.h. or 154 km/h).

Tropical Cyclone Garance dropped very heavy rain on La Reunion.  There were reports of flooding.  Roland Garros airport (FMEE) measured 6.48 inches (164.6 mm) of rain.  A weather station at Piton-Maido reported 18.49 inches (469.6 mm) of rain.  A weather station at Cilaos reported 17.06 inches (433.4 mm) of rain.

Tropical Cyclone Garance was a small tropical cyclone when it hit La Reunion.  Winds to hurricane/typhoon force extended out 25 miles (40 km) from the center of Garance’s circulation.  Winds to tropical storm force extended out 105 miles (165 km) from the center of Tropical Cyclone Garance.

The Hurricane Intensity Index (HII) for Tropical Cyclone Garance was 17.8.  The Hurricane Size Index (HSI) was 8,8 and the Hurricane Wind Intensity Size Index (HWISI) was 26.6.  Tropical Cyclone Garance was similar in size and intensity to Hurricane Zeta when Zeta hit Louisiana in 2020.

Tropical Cyclone Garance will be pulled around the eastern side of the larger circulation around Tropical Cyclone Honde.  Garance will move toward the south during the next 24 hours.  On its anticipated track, Tropical Cyclone Garance will move south of La Reunion later today.

Tropical Cyclone Garance will weaken significantly during its passage over La Reunion.  Tropical Cyclone Garance will move through an environment that will become unfavorable for intensification during the next 24 hours.  Garance will move over water where where the Sea Surface Temperatures are near 28°C.  However, it will move under the upper level outflow from Tropical Cyclone Honde.  The upper level outflow from Honde’s circulation will cause the vertical wind shear to increase over Garance.  The increase in vertical wind shear will cause Tropical Cyclone Garance to weaken during the next 24 hours.

Elsewhere over the Southwest Indian Ocean, Tropical Cyclone Honde brought strong winds and heavy rain  to southern Madagascar.  At 4:00 a.m. EST on Friday the center of Tropical Cyclone Honde was located at latitude 26.1°S and longitude 44.0°E which put the center about 190 miles (305 km) south of Toliara, Madagascar.  Honde was moving toward the east-southeast at 9 m.p.h. (15 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).  The minimum surface pressure was 974 mb.

Tropical Cyclone Garance Intensifies to Equivalent of Major Hurricane

Tropical Cyclone Garance intensified to the equivalent of a major hurricane north of La Reunion on Thursday.  At 4:00 a.m. EST on Thursday the center of Tropical Cyclone Garance was located at latitude 18.5°S and longitude 55.4°E which put the center about 155 miles (205 km) north of St. Denis, La, Reunion.  Garance was moving toward the southeast at 5 m.p.h. (8 km/h). 0 The maximum sustained wind speed was 120 m.p.h. (195 km/h) and there were wind gusts to 150 m.p.h. (240 km/h).  The minimum surface pressure was 955 mb.

Tropical Cyclone Garance intensified to the equivalent of a major hurricane north of La Reunion on Thursday.  A circular eye with a diameter of 17 miles (28 km) was at the center of Garance’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 Garance’s circulation.  Storms near the center 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 Garance was small.  Winds to hurricane/typhoon force extended out 35 miles (55 km) from the center of Garance’s circulation.  Winds to tropical storm force extended out 105 miles (165 km) from the center of Tropical Cyclone Garance.

The Hurricane Intensity Index (HII) for Tropical Cyclone Garance was 22.1.  The Hurricane Size Index (HSI) was 12.3 and the Hurricane Wind Intensity Size Index (HWISI) was 34.4. Tropical Cyclone Garance was similar in size and intensity to Hurricane Dennis when Dennis hit Northwest Florida in 2005.

Tropical Cyclone Garance will move through an environment favorable for intensification during the next 12 hours.  Garance will move over water where where the Sea Surface Temperatures are near 29°C.  It will move under an upper level ridge that is east of Madagascar.  The upper level winds are weak in the ridge and there will be little vertical wind shear.  Tropical Cyclone Garance could continue to intensify during the next 12 hours unless an eyewall replacement cycle occurs.

Tropical Cyclone Garance is likely to get pulled into the eastern side of the larger circulation around Tropical Cyclone Honde, which is over the southern Mozambique Channel.  The larger circulation around Honde will steer Garance toward the south during the next 24 hours.  On its anticipated track, Tropical Cyclone Garance will reach La Reunion within the next 18 hours.

Tropical Cyclone Garance is likely to be the equivalent of a major hurricane when it reaches La Reunion.  Garance will be capable of causing major damage on La Reunion.  Tropical Cyclone Garance will also drop heavy rain on La Reunion.  Heavy rain is likely to cause widespread flash flooding.  Garance could cause a storm surge of up to 10 feet (3 meters) along the coast of La Reunion.

Bands in the eastern side of Tropical Cyclone Garance could also bring strong winds and heavy rain to Mauritius.  There were reports that the airport on Mauritius was closed as a precaution.

Elsewhere, Tropical Cyclone Honde intensified to the equivalent of a hurricane/typhoon over the southern Mozambique Channel near Madagascar.  At 4:00 a.m. EST on Thursday the center of Tropical Cyclone Honde was located at latitude 25.0°S and longitude 41.8°E which put the center about 170 miles (280 km) southwest of Toliara, Madagascar.  Honde was moving toward the southeast at 13 m.p.h. (21 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 970 mb.

Tropical Cyclone Honde will bring strong winds and locally heavy rain to southern Madagascar.  Heavy rain is likely to cause flash floods in some locations.

Tropical Cyclone Garance Intensifies to Equivalent of Hurricane/Typhoon

Tropical Cyclone Garance intensified to the equivalent of a hurricane/typhoon north-northwest of La Reunion on Wednesday.  At 4:00 p.m. EST on Wednesday the center of Tropical Cyclone Garance was located at latitude 17.8°S and longitude 54.7°E which put the center about 200 miles (325 km) north-northwest of St. Denis, La, Reunion.  Garance was moving toward the east-southeast at 5 m.p.h. (8 km/h).  The maximum sustained wind speed was 100 m.p.h. (160 km/h) and there were wind gusts to 120 m.p.h. (195 km/h).  The minimum surface pressure was 974 mb.

Tropical Cyclone Garance rapidly intensified to the equivalent of a hurricane/typhoon over the Southwest Indian Ocean north-northwest of La Reunion on Wednesday.  The inner end of a rainband wrapped around the center of Garance’s circulation.  A small circular eye appeared to be forming at the center of Tropical Cyclone Garance.  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 center of Garance’s circulation.  Storms near the center 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 Garance was small.  Winds to hurricane/typhoon force extended out 35 miles (55 km) from the center of Garance’s circulation.  Winds to tropical storm force extended out 100 miles (160 km) from the center of Tropical Cyclone Garance.

The Hurricane Intensity Index (HII) for Tropical Cyclone Garance was 16.5  The Hurricane Size Index (HSI) was 11.2 and the Hurricane Wind Intensity Size Index (HWISI) was 27.7.  Tropical Cyclone Garance was similar in size and intensity to Hurricane Idalia when Idalia hit Florida in 2023.

Tropical Cyclone Garance will move through an environment favorable for intensification during the next 24 hours.  Garance will move over water where where the Sea Surface Temperatures are near 30°C.  It will move under the northern side of an upper level low that is southeast of La Reunion.  The upper level low will produce westerly winds that will blow toward the top of Garance’s circulation.  Those winds will some vertical wind shear.  The vertical wind shear will inhibit intensification, but the wind shear will not be enough to prevent intensification. Tropical Cyclone Garance will intensify during the next 24 hours.  Garance is likely to strengthen to the equivalent of a major hurricane.

Tropical Cyclone Garance could get pulled into the eastern side of the larger circulation around Tropical Cyclone Honde, which is over the Mozambique Channel.  The larger circulation around Honde will steer Garance toward the south during the next 24 hours.  On its anticipated track, Garance will approach La Reunion in 24 hours.

Tropical Cyclone Garance is likely to be the equivalent of a major hurricane when it reaches La Reunion.  Garance will be capable of causing major damage on La Reunion.  Tropical Cyclone Garance will also drop heavy rain on La Reunion.  Heavy rain is likely to cause widespread flash flooding.  Garance could cause a storm surge of up to 10 feet (3 meters) along the coast of La Reunion.

Elsewhere, Tropical Cyclone Honde was intensifying over the Mozambique Channel.  At 4:00 p.m. EST on Wednesday the center of Tropical Cyclone Honde was located at latitude 24.1°S and longitude 40.2°E which put the center about 255 miles (410 km) west of Toliara, Madagascar. Honde was moving toward the east-southeast at 7 m.p.h. (11 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).  The minimum surface pressure was 981 mb.

Tropical Cyclone Garance Forms Northwest of La Reunion

Tropical Cyclone Garance formed over the Southwest Indian Ocean northwest of La Reunion on Tuesday morning.  At 10:00 a.m. EST on Tuesday the center of Tropical Cyclone Garance was located at latitude 18.3°S and longitude 52.1°E which put the center about 270 miles (435 km) northwest of St. Denis, La, Reunion.  Garance was moving toward the east-northeast at 3 m.p.h. (5 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 1001 mb.

A low pressure system over the Southwest Indian Ocean northwest of La Reunion strengthened on Tuesday morning and Meteo France La Reunion designated the system as Tropical Cyclone Garance.  The distribution of thunderstorms was asymmetrical in Tropical Cyclone Garance.  Thunderstorms were occurring in bands in the western and northern parts of Garance’s circulation.  Bands in the eastern and southern parts of Tropical Cyclone Garance consisted primarily of showers and lower clouds.  Storms near the center of Garance began to generate upper level divergence that pumped mass away from the tropical cyclone.

The circulation around Tropical Cyclone Garance was small.  Winds to tropical storm force extended out 50 miles (80 km) from the center of Garance’s circulation.

Tropical Cyclone Garance will move through an environment favorable for intensification during the next 24 hours.  Garance will move over water where where the Sea Surface Temperatures are near 30°C.  It will move under the northwestern side of an upper level low that is southeast of La Reunion.  The upper level low will produce southwesterly winds that will blow toward the top of Garance’s circulation.  Those winds will cause moderate vertical wind shear.  The vertical wind shear will inhibit intensification, but the wind shear will not be enough to prevent intensification.  Tropical Cyclone Garance will intensify during the next 24 hours.

The upper level low southeast of La Reunion will steer Tropical Cyclone Garance slowly toward the east during the next 24 hours.  On its anticipated track, Tropical Cyclone Garance will approach La Reunion and Mauritius in 36 hours.

Tropical Cyclone Garance could be the equivalent of a hurricane/typhoon when it approaches La Reunion and Mauritius.

Elsewhere over the Southwest Indian Ocean, a tropical depression formed over the Mozambique Channel.  At 10:00 a.m. EST on Tuesday the center of the tropical depression was located at latitude 22.9°S and longitude 37.1°E which put the center about 405 miles (655 km) west of Toliara, Madagascar.   The tropical depression was moving toward the south-southeast at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 996 mb.

Tropical Cyclone Paul Weakens

Tropical Cyclone Paul weakened over the Coral Sea on Thursday night. At 11:00 p.m. EDT on Thursday the center of Tropical Cyclone Paul was located at latitude 15.2°S and longitude 156.5°E which put it about 325 miles (525 km) southeast of the Tagula Island. Paul was moving toward the east at 4 m.p.h. (6 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 1001 mb.

Tropical Cyclone Paul strengthened earlier on Thursday when it was in a more favorable environment. Then an upper level trough near the east coast of Australia began to produce strong west-northwesterly winds that blew across the top of Paul’s circulation. Those winds caused the vertical wind shear to increase. The stronger vertical wind shear blew the tops off of many of the thunderstorms in Tropical Cyclone Paul. A few thunderstorms were still occurring in bands in the southeastern part of Paul’s circulation. Bands in the other parts of Tropical Cyclone Paul consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 40 miles (65 km) from the center of Paul.

Tropical Cyclone Paul will move through an environment unfavorable for intensification during the next 24 hours. Paul will move over water where the Sea Surface Temperatures are near 29°C. However, the upper level trough near eastern Australia will continue to produce strong west-northwesterly winds that will blow across the top of Paul’s circulation. Those winds will cause strong vertical wind shear. The strong wind shear will cause Paul to continue to weaken.

Tropical Cyclone Paul will be steered by the winds in the lower levels of the atmosphere because of the strong vertical wind shear. Paul will move around the northern side of high pressure system over the Southwest Pacific Ocean and eastern Australia. The high pressure system will steer Paul toward the west-northwest during the next 24 hours. On its anticipated track, Tropical Cyclone Paul will weaken over the Coral Sea.

Tropical Cyclone Paul Forms over Coral Sea

Tropical Cyclone Paul formed over the Coral Sea on Wednesday. At 5:00 p.m. EDT on Wednesday the center of Tropical Cyclone Paul was located at latitude 13.8°S and longitude 154.3°E which put it about 150 miles (240 km) south-southeast of the Tagula Island. Paul was moving toward the south-southeast at 7 m.p.h. (11 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 1000 mb.

A low pressure system over the Coral Sea southeast of New Guinea strengthened on Wednesday and the Australian Bureau of Meteorology designated the system as Tropical Cyclone Paul. More thunderstorms formed near the center of Tropical Cyclone Paul. The inner end of a rainband wrapped around the northern side of the center of Paul’s circulation. Storms near the center generated upper level divergence that pumped mass away from the tropical cyclone. Bands of showers and thunderstorms were revolving around the center of Tropical Cyclone Paul. The circulation around Paul was small. Winds to tropical storm force extended out 30 miles (50 km) from the center of Paul’s circulation.

Tropical Cyclone Paul will move through an environment favorable for intensification during the next 24 hours. Paul will move over water where the Sea Surface Temperatures are near 29°C. An upper level trough over eastern Australia will produce west-northwesterly winds that will blow toward the top of Paul’s circulation. Those winds will cause moderate vertical wind shear. The wind shear will inhibit intensification. Tropical Cyclone Paul could intensify during the next 24 hours despite the wind shear. The vertical wind shear is forecast to increase on Friday. Paul will start to weaken when the wind shear increases.

Tropical Cyclone Paul will be in an area where the steering winds are weak during the next 24 hours. Tropical Cyclone Paul will not move much during the next day or so. A high pressure system over the Southwest Pacific Ocean and eastern Australia is likely to start to steer Paul toward the west on Friday. On its anticipated track, Tropical Cyclone Paul will eventually start to move toward the northern Cape York Peninsula.

Elsewhere, a weakening Tropical Cyclone Olga was passing near Exmouth, Australia. At 5:00 p.m. EDT on Wednesday the center of Tropical Cyclone Olga was located at latitude 21.4°S and longitude 114.3°E which put it about 85 miles (135 km) north-northeast of the Exmouth, Australia. Olga was moving toward the southwest at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h). The minimum surface pressure was 1007 mb. A weather station on Barrow Island reported a sustained wind speed of 37 m.p.h. (59 km/h) and a wind gust of 45 m.p.h. (72 km/h).

Tropical Cyclone Halima Still Meandering Southeast of Diego Garcia

Tropical Cyclone Halima continued to meander over the South Indian Ocean southeast of Diego Garcia on Thursday. At 11:00 p.m. EDT on Thursday the center of Tropical Cyclone Halima was located at latitude 19.4°S and longitude 84.0°E which put it about 1145 miles (1850 km) southeast of Diego Garcia. Halima was moving toward the west-northwest 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 997 mb.

Tropical Cyclone Halima maintained its intensity as it continued to meander over the South Indian Ocean southeast of Diego Garcia on Thursday. The distribution of thunderstorms and wind around Tropical Cyclone Halima was asymmetrical. The strongest thunderstorms were occurring in bands in the southern half of Halima’s circulation. The strongest winds were also occurring in those bands. Bands in the northern half of the circulation consisted primarily of showers and lower clouds. The winds were weaker on the northern side of Tropical Cyclone Halima. Storms near the center of Halima generated upper level divergence that pumped mass away to the southeast of the tropical cyclone. Winds to tropical storm force extended out 90 miles (145 km) in the southern half of Tropical Cyclone Halima. Winds to tropical storm force only extended out 15 miles (25 km) on the northern half of Halima.

Tropical Cyclone Halima will move through an environment that will continue to be unfavorable for intensification during the next 24 hours. Halima will move over water where the Sea Surface Temperatures are near 26˚C. However, an upper level trough over the South Indian Ocean will produce northwesterly winds that will blow toward the top of Halima’s circulation. Those winds will cause moderate vertical wind shear. The wind shear will inhibit intensification of Tropical Cyclone Halima during the next 24 hours.

Tropical Cyclone Halima will move north of a high pressure system over the South Indian Ocean during the next 24 hours. The high pressure will steer Halima toward the west. On its anticipated track Tropical Cyclone Halima will remain far southeast of Diego Garcia during the next 24 hours.

Tropical Cyclone Halima Weakens Southeast of Diego Garcia

Tropical Cyclone Halima weakened over the South Indian Ocean southeast of Diego Garcia on Wednesday. At 11:00 p.m. EDT on Wednesday the center of Tropical Cyclone Halima was located at latitude 19.3°S and longitude 83.4°E which put it about 1110 miles (1790 km) southeast of Diego Garcia. Halima was moving toward the east-northeast at 9 m.p.h (15 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 1000 mb.

Tropical Cyclone Halima weakened gradually southeast of Diego Garcia on Wednesday. Even though it weakened, the circulation around Halima remained organized. A band of thunderstorms wrapped around the southern and western sides of the center of circulation. Storms near the center generated upper level divergence that pumped mass away to the east of Tropical Cyclone Halima. Other thunderstorms formed in bands in the eastern half of Halima’s circulation. Bands in the western half of the circulation consisted primarily of showers and lower clouds. Wind to tropical storm force extended out 70 miles (110 km) from the center of circulation.

Tropical Cyclone Halima will move through an environment that will continue to be unfavorable for intensification during the next 24 hours. Halima will move over water where the Sea Surface Temperatures are near 26˚C. However, an upper level trough over the South Indian Ocean will produce west-northwesterly winds that will blow toward the top of Halima’s circulation. Those winds will cause moderate vertical wind shear. The wind shear will inhibit intensification of Tropical Cyclone Halima during the next 24 hours.

Tropical Cyclone Halima will move around the southeastern part of a high pressure system over the South Indian Ocean during the next 24 hours. The high pressure system will steer Halima toward the east-northeast. On its anticipated track Tropical Cyclone Halima will remain far southeast of Diego Garcia during the next 24 hours.
