Tropical Cyclone Lucas Brushes New Caledonia

Tropical Cyclone Lucas brushed New Caledonia on Tuesday night. At 10:00 p.m. EST on Tuesday the center of Tropical Cyclone Lucas was located at latitude 22.2°S and longitude 167.0°E which put it about 75 miles (120 km) east-northeast of Noumea, New Caledonia. Lucas was moving toward the south 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 991 mb.

Tropical Cyclone Lucas brought gusty winds and locally heavy rain to parts of southern New Caledonia on Tuesday night. Lucas weakened before it reached New Caledonia. An upper level trough east of Australia produced strong northwesterly winds that blew toward the top of Tropical Cyclone Lucas. Those winds caused strong vertical wind shear and they blew the tops off of thunderstorms around the center of Lucas. Drier air wrapped around the northern side of the tropical cyclone, which caused some of the outer rainbands to weaken as well. Tropical Cyclone Lucas was the equivalent of a tropical storm when it moved near southern New Caledonia. Winds to tropical storm force extended out 150 miles (240 km) from the center of Lucas.

Since many of the stronger thunderstorms in the circulation around Tropical Cyclone Lucas have weakened, the system will be steered by winds lower in the atmosphere. A high pressure system north of New Zealand will steer Lucas slowly toward the west during the next several days. On its anticipated track Tropical Cyclone Lucas will continue to bring gusty winds and locally heavy rain to parts of southern New Caledonia for another 24 hours.

Tropical Cyclone Lucas Strengthens to Equivalent of Hurricane/Typhoon

Tropical Cyclone Lucas strengthened to the equivalent of a hurricane/typhoon over the Coral Sea on Monday. At 10:00 a.m. EST on Monday the center of Tropical Cyclone Lucas was located at latitude 16.1°S and longitude 163.1°E which put it about 495 miles (800 km) north-northeast of Noumea, New Caledonia. Lucas was moving toward the southeast at 22 m.p.h. (35 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 973 mb.

Tropical Cyclone Lucas intensified north of New Caledonia on Monday. A microwave satellite image showed a small eye forming at the center of Lucas. The inner end of a rainband wrapped around the northern and eastern sides of the developing eye. Bands of showers and thunderstorms were revolving around the center of Tropical Cyclone Lucas. The strongest bands were in the eastern half of the circulation. Storms near the center of circulation generated upper level divergence which pumped mass away to the southeast of the tropical cyclone. Winds to hurricane/typhoon force extended out 25 miles (40 km) from the center of Lucas. Winds to tropical storm force extended out 170 miles (280 km) from the center of circulation.

Tropical Cyclone Lucas will move through an environment only marginally favorable for intensification. Lucas will move over water where the Sea Surface Temperature is near 29°C. An upper level trough east of Australia will produce northwesterly winds which blow toward the top of the tropical cyclone. Those winds will cause moderate vertical wind shear and they will inhibit intensification. The vertical wind shear could be strong enough to prevent intensification of Tropical Cyclone Lucas even though it will move over warm water.

Tropical Cyclone Lucas will move around the southwestern part of a high pressure system during the next 24 hours. That high pressure system will steer Lucas toward the southeast during the next day or so. A second high pressure system over the South Pacific Ocean will start to steer Tropical Cyclone Lucas more toward the south later on Tuesday. On its anticipated track Lucas could approach New Caledonia within 36 hours.

Tropical Cyclone Bina Develops Northwest of Fiji

Tropical Cyclone Bina developed northwest of Fiji on Sunday. At 10:00 a.m. EST on Sunday the center of Tropical Cyclone Bina was located at latitude 14.0°S and longitude 175.7°E which put it about 315 miles (510 km) northwest of Labasa, Fiji. Bina was moving toward the southeast at 16 m.p.h. (26 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 994 mb.

As Tropical Cyclone Ana was moving away from Fiji, Tropical Cyclone Bina developed northwest of that nation. A low pressure system northwest of Fiji strengthened on Sunday and the Fiji Meteorological Service designated the system as Tropical Cyclone Bina. More thunderstorms formed near the center of Bina. Those storms generated upper level divergence which pumped mass away from the tropical cyclone. The circulation around Tropical Cyclone Bina was small. Winds to tropical storm force only extended out 80 miles (130 km) from the center of Bina.

Tropical Cyclone Bina will move through an environment marginally favorable for intensification during the next 24 hours. Bina will move over water where the Sea Surface Temperature is near 28°C. An upper level trough east of Australia will produce northwesterly winds which blow toward the top of the tropical cyclone. Those winds will cause moderate vertical wind shear and they will inhibit intensification. Tropical Cyclone Bina will likely maintain its intensity during the next 24 hours.

The upper level trough will steer Tropical Cyclone Bina toward the southeast during the next 36 hours. On its anticipated track Bina could reach Vanua Levu within 18 hours. Tropical Cyclone Bina will bring gusty winds and locally heavy rain to Fiji during the next 36 hours. The stormy conditions will make efforts on Viti Levu and Vanua Levu to recover from Tropical Cyclone Ana more difficult. Heavy rain could make floods caused by Ana to become worse.

Elsewhere over the Southwest Pacific Ocean, Tropical Cyclone Ana was moving away from Fiji and Tropical Cyclone Lucas was strengthening over the Coral Sea. At 10:00 p.m. EST on Sunday the center of Tropical Cyclone Ana was located at latitude 19.9°S and longitude 179.7°E which put it about 105 miles (17 km) south of Suva, Fiji. Ana was moving toward the south-southeast at 9 m.p.h. (15 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 978 mb.

At 10:00 p.m. EST on Sunday the center of Tropical Cyclone Lucas was located at latitude 13.2°S and longitude 156.0°E which put it about 870 miles (1405 km) west-northwest of New Caledonia. Lucas was moving toward the east at 17 m.p.h. (28 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 979 mb. Tropical Cyclone Lucas is forecast to strengthen into the equivalent of a hurricane/typhoon. It could affect New Caledonia and Vanuatu in a few days.
