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).
