Tropical Cyclone Kevin Forms West of Vanuatu

Tropical Cyclone Kevin formed over the Coral Sea west of Vanuatu on Wednesday. At 10:00 p.m. EST on Wednesday the center of Tropical Cyclone Kevin was located at latitude 14.8°S and longitude 163.2°E which put it about 430 miles (695 km) west-northwest of Port Vila, Vanuatu. Kevin was moving toward the east-southeast at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h). The minimum surface pressure was 991 mb.

A low pressure system over the Coral Sea west of Vanuatu strengthened on Wednesday and the Fiji Meteorological Service designated the system as Tropical Cyclone Kevin. The circulation Tropical Cyclone Kevin organized quickly. The inner end or a rainband wrapped around the northern and eastern sides of the center of Kevin’s circulation. Other bands of showers and thunderstorms were revolving around the center of Tropical Cyclone Kevin. Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical cyclone. Winds to tropical storm force extended out 130 miles (210 km) from the center of Kevin.

Tropical Cyclone Kevin will move through an environment favorable for intensification during the next 36 hours. Kevin will move over over water where the Sea Surface Temperatures are near 30˚C. It will move under the middle of an upper level ridge over the Coral Sea. The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear. Tropical Cyclone Kevin will rapidly intensify to the equivalent of a hurricane/typhoon during the next 24 hours. Kevin could strengthen to the equivalent of a major hurricane within 36 hours.

An upper level trough east of Australia will steer Tropical Cyclone Kevin toward the east-southeast during the next 36 hours. On its anticipated track, the center of Tropical Cyclone Kevin will pass west of Espiritu Santo and Malekula during the next 24 hours. Kevin will bring gusty winds and locally heavy rain to Espiritu Santo and Malekula. Heavy rain could cause flash floods in some locations. The center of Tropical Cyclone Kevin could pass near Port Vila, Vanuatu within 36 hours. Kevin could be the equivalent of a major hurricane when it passes near Port Vila. Tropical Cyclone Kevin could bring strong winds and locally heavy rain to Port Vila and Efate. Port Vila and Efate were just hit by Tropical Cyclone Judy. Tropical Cyclone Kevin will hinder efforts to recover from Tropical Cyclone Judy.

Elsewhere over the South Pacific Ocean, Tropical Cyclone Judy moved quickly away from Vanuatu. At 10:00 p.m. EST on Wednesday the center of Tropical Cyclone Judy was located at latitude 22.9°S and longitude 172.9°E which put it about 450 miles (650km) east of Noumea, New Caledonia. Judy was moving toward the southeast at 16 m.p.h. (26 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 964 mb.
