Tropical Cyclone Lincoln Moves Toward Western Australia

Tropical Cyclone Lincoln moved toward the coast of Western Australia on Friday. At 4:00 p.m. EST on Friday the center of Tropical Cyclone Lincoln was located at latitude 20.0°S and longitude 113.3°E which put it about 200 miles (320 km) north of Exmouth, Australia. Lincoln was moving toward the south-southwest at 5 m.p.h. (8 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 Warning was in effect for the coast of Western Australia from Giralia to Cape Cuvier. The Warning included Exmouth, Ningaloo, and Coral Bay.

Tropical Cyclone Lincoln maintained its intensity on Friday, but the distribution of thunderstorms was asymmetrical. Thunderstorms were occurring mainly in bands in the western half of Lincoln’s circulation. Bands in the eastern half of Tropical Cyclone Lincoln consisted primarily of showers and lower clouds. Storms near the center of Lincoln’s circulation generated upper level divergence that pumped mass away to the south of the tropical cyclone. Winds to tropical storm force extended out 50 miles (80 km) from the center of Tropical Cyclone Lincoln.

Tropical Cyclone Lincoln will move through an environment marginally favorable for intensification during the next 24 hours. Lincoln will move over water where the Sea Surface Temperatures are near 28°C. However, an upper level trough over the South Indian Ocean west of Australia will produce northwesterly winds that will blow toward the top of Lincoln’s circulation. Those winds will cause moderate vertical wind shear. The wind shear will inhibit intensification, but Tropical Cyclone Lincoln could maintain its intensity during the next 24 hours.

The upper level trough west of Australia will steer Tropical Cyclone Lincoln toward the south during the next 24 hours. On its anticipated track, Tropical Cyclone Lincoln will approach the coast of Western Australia between Exmouth and Cape Cuvier in 24 hours. Lincoln will bring gusty winds and locally heavy rain to Western Australia. Heavy rain could cause flash floods in some locations.

Tropical Cyclone Eleanor Weakens South of Mauritius

Tropical Cyclone Eleanor weakened south of Mauritius on Friday. At 10:00 a.m. EST on Friday the center of Tropical Cyclone Eleanor was located at latitude 23.9°S and longitude 58.4°E which put it about 265 miles (430 km) south-southeast of Port Louis, Mauritius. Eleanor was moving toward the south at 5 m.p.h. (8 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 995 mb.

An upper level trough southeast of Madagascar produced strong northwesterly winds that blew across the top of Tropical Cyclone Eleanor. Those winds caused strong vertical wind shear. The strong upper level winds also blew the upper part pf Eleanor’s circulation to the southeast of the circulation in the lower levels of the atmosphere. Bands revolving around the center of Tropical Cyclone Eleanor consisted primarily of showers and lower clouds. A few thunderstorms were still occurring in bands in the southeastern periphery of Eleanor’s circulation. Winds to tropical storm force extended out 140 miles (225 km) from the center of Tropical Cyclone Eleanor.

Tropical Cyclone Eleanor will move through an environment unfavorable for intensification during the next 36 hours. Eleanor will move over water where the Sea Surface Temperatures are near 27°C. However, the upper level trough south of Madagascar will continue to cause strong vertical wind shear. The strong wind shear will cause Tropical Cyclone Eleanor to continue to weaken during the next 36 hours.

Since the circulation around Tropical Cyclone Eleanor exists in the lower levels of the atmosphere, it will be steered by winds in those levels. Eleanor will move around the northern side of a high pressure system over the South Indian Ocean. The high pressure system will steer Eleanor toward the west. On its anticipated track, Tropical Cyclone Eleanor will move south of Mauritius and La Reunion during the next 36 hours.

Elsewhere over the South Indian Ocean, Tropical Cyclone Lincoln continued to spin near the coast of Western Australia. At 10:00 a.m. EST on Friday the center of Tropical Cyclone Lincoln was located at latitude 19.3°S and longitude 113.5°E which put it about 245 miles (395 km) north of Exmouth, Australia. Lincoln was moving toward the 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 Warning was in effect for the portion of the coast from Onslow to Wooramel Roadhouse, Australia. The Warning included Exmouth and Carnarvon.

Tropical Cyclone Lincoln Prompts Warning for Western Australia

The potential risk posed by Tropical Cyclone Lincoln prompted the Australian Bureau of Meteorology to issue a Warning for a portion of the coast of Western Australia on Thursday. At 10:00 a.m. EST on Thursday the center of Tropical Cyclone Lincoln was located at latitude 17.8°S and longitude 117.7°E which put it about 175 miles (280 km) north of Port Hedland, Australia. Lincoln was moving toward the southwest at 15 m.p.h. (24 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 992 mb.

A Warning was in effect for the portion of the coast from Mardie to Ningaloo, Australia. The Warning included Exmouth and Onslow. A Watch was in effect for the portion of the coast from Ningaloo to Wooramel Roadhouse, Australia. The Watch included Carnarvon.

Tropical Cyclone Lincoln was strengthening gradually as it moved over the South Indian Ocean near Western Australia on Thursday. Even though Lincoln was strengthening, the distribution of thunderstorms was asymmetrical. Thunderstorms were occurring in bands in the northern and western parts of Tropical Cyclone Lincoln. Bands in the southern and eastern parts of Lincoln’s circulation consisted primarily of showers and lower clouds. An upper level ridge over Australia was producing northeasterly winds that were blowing toward the top of Tropical Cyclone Lincoln. Those winds were causing moderate vertical wind shear and the wind shear was causing the asymmetrical distribution of thunderstorms. Winds to tropical storm force extended out 85 miles (135 km) from the center of Lincoln’s circulation.

Tropical Cyclone Lincoln will move through an environment somewhat favorable for intensification during the next 24 hours. Lincoln will move over water where the Sea Surface Temperatures are near 28°C. However, the upper level ridge over Australia will continue to cause vertical wind shear. The wind shear will inhibit intensification, but the shear may not be enough to prevent intensification. Tropical Cyclone Eleanor is likely to strengthen gradually during the next 24 hours.

Tropical Cyclone Lincoln will move around the northwestern part of a high pressure system over Australia. The high pressure system will steer Lincoln toward the southwest during the next 24 hours. Lincoln will move more toward the south when it reaches the western end of the high pressure system on Friday. Tropical Cyclone Lincoln could approach the coast of Western Australia between Mardie and Caranarvon in 36 hours.

Tropical Cyclone Eleanor Moves Southeast of Mauritius

Tropical Cyclone Eleanor moved southeast of Mauritius on Thursday morning. At 10:00 a.m. EST on Thursday the center of Tropical Cyclone Eleanor was located at latitude 21.7°S and longitude 58.4°E which put it about 120 miles (195 km) southeast of Port Louis, Mauritius. Eleanor was moving toward the south-southeast at 15 m.p.h. (24 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 992 mb.

Bands in the western part of Tropical Cyclone Eleanor produced gusty winds and rain showers in Mauritius on Thursday. A weather station at the Sir Seewoosagur Ramgoolam International Airport (FIMP) in Port St. Louis reported a sustained wind speed of 26 m.p.h. (43 km/h) and a wind gust of 40 m.p.h. (65 km/h).

The distribution of thunderstorms in Tropical Cyclone Eleanor was asymmetrical. Thunderstorms were occurring in bands in the eastern and southern parts of Eleanor’s circulation. Bands in the northern and western parts of Tropical Cyclone Eleanor consisted primarily of showers and lower clouds. An upper level trough south of Madagascar produced northwesterly winds that blew toward the top of Eleanor’s circulation. Those winds caused moderate vertical wind shear and the wind shear caused the asymmetrical distribution of thunderstorms. Winds to tropical storm force extended out 125 miles (200 km) from the center of Eleanor’s circulation.

Tropical Cyclone Eleanor will move through an environment somewhat favorable for intensification during the next 24 hours. Eleanor will move over water where the Sea Surface Temperatures are near 28°C. However, the upper level trough south of Madagascar will continue to cause moderate vertical wind shear. The wind shear will inhibit intensification, but Tropical Cyclone Eleanor could strengthen a little during the next 24 hours.

Tropical Cyclone Eleanor will move around the northwestern part of a high pressure system over the South Indian Ocean. The high pressure system will steer Eleanor toward the south-southwest during the next 24 hours. On its anticipated track, Tropical Cyclone Eleanor will gradually move farther to the south-southeast of Mauritius.

Tropical Cyclone Gabekile Develops South of Diego Garcia

Tropical Cyclone Gabekile developed south of Diego Garcia on Saturday.  At 10:00 a.m. EST on Saturday the center of Tropical Cyclone Gabekile was located at latitude 17.4°S and longitude 74.1°E which put it about 700 miles (1125 km) south of Diego Garcia.  Gabekile was moving toward the south-southwest at 5 m.p.h. (8 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 995 mb.

The circulation around Tropical Cyclone Gabekile was small but well organized.  Some microwave images suggested that a small eye could be forming at the center of circulation.  The eyelike feature was surrounded by a tight ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the small core of Gabekile.  Storms near the core generated upper level divergence which pumped mass away from the tropical cyclone.  Winds to tropical storm force extended out 65 miles (105 km) from the center of circulation.

Tropical Cyclone Gabekile will move through an environment favorable for intensification during the next several days.  Gabekile will move over water where the Sea Surface Temperature is near 28°C.  It will move under the western end of an upper level ridge over the South Indian Ocean.  The ridge will produce northerly winds which will blow toward the top of the circulation.  Those winds will cause some vertical wind shear, but the shear will not be strong enough to prevent intensification.  Tropical Cyclone Gabekile could strengthen into the equivalent of a hurricane/typhoon.

Tropical Cyclone Gabekile will move around the western end of a high pressure system over the South Indian Ocean.  The high will steer Gabekile  toward the south.  On its anticipated track Tropical Cyclone Gabekile will move farther away from Diego Garcia.

Elsewhere over the South Indian Ocean, Tropical Cyclone Francisco was weakening as it moved slowly inland over east-central Madagascar.  At 7:00 a.m. EST on Saturday the center of Tropical Cyclone Francisco was located at latitude 20.0°S and longitude 48.3°E which put it about 10 miles (15 km) north of Marolambo, Madagascar.  Francisco was moving toward the southwest at 4 m.p.h. (6 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 1007 mb.  Tropical Cyclone Francisco was dropping locally heavy rain over parts of Madagascar.
