Tropical Cyclone Forms over Coral Sea

Tropical Cyclone 03P formed over the Coral Sea southwest of the Solomon Islands on Saturday. At 4:00 p.m. EST on Saturday the center of Tropical Cyclone 03P was located at latitude 13.2°S and longitude 157.1°E which put it about 650 miles (1050 km) northwest of Poum, New Caledonia. Tropical Cyclone 03P was moving toward the south-southeast at 16 m.p.h. (26 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 997 mb.

The circulation around a small low pressure system over the Coral Sea strengthened on Saturday into Tropical Cyclone 03P. More thunderstorms formed near the center of the tropical cyclone. Thunderstorms also became more numerous in bands revolving around the center of circulation. Storms near the center generated upper level divergence that pumped mass away from the tropical cyclone. The circulation around the tropical cyclone was small. Winds to tropical storm force extended out 20 miles (30 km) from the center of circulation.

Tropical Cyclone 03P will move through an environment favorable for intensification during the next 36 hours. The tropical cyclone will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the western part of an upper level ridge over the South Pacific Ocean. The ridge will produce northwesterly winds that will blow toward the top of the tropical cyclone’s circulation. Those winds will cause some vertical wind shear, but the wind shear will be too small to prevent intensification. Tropical Cyclone 03P will intensify and it could strengthen to the equivalent of a hurricane/typhoon within 36 hours.

Tropical Cyclone 03P will move around the southwestern part of a high pressure system over the South Pacific Ocean during the next several days. The high pressure system will steer the tropical cyclone toward the southeast during the next 36 hours. On its anticipated track Tropical Cyclone 03P could approach the northwestern part of New Caledonia in 48 hours. The tropical cyclone is likely to be the equivalent of a hurricane/typhoon when it nears New Caledonia.
