Tropical Cyclone Kevin Passes South of Fiji

Tropical Cyclone Kevin passed south of Fiji on Saturday. At 4:00 p.m. EST on Saturday the center of Tropical Cyclone Kevin was located at latitude 25.1°S and longitude 178.6°E which put it about 450 miles (720 km) south of Suva, Fiji. Kevin was moving toward the east-southeast at 26 m.p.h. (43 km/h). The maximum sustained wind speed was 120 m.p.h. (195 km/h) and there were wind gusts to 150 m.p.h. (240 km/h). The minimum surface pressure was 951 mb.

Tropical Cyclone Kevin started to weaken as it passed south of Fiji on Saturday. An upper level trough east of Australia was producing northwesterly winds that were blowing toward the top of Kevin’s circulation. Those winds were causing moderate vertical wind shear and the wind shear was causing Kevin to weaken. A large circular eye with a diameter of 50 miles (80 km) was at the center of Tropical Cyclone Kevin. The eye was surrounded by a broken ring of thunderstorms and the strongest winds were occurring in that ring of storms. The vertical wind shear also caused the distribution of thunderstorms in Kevin to become asymmetrical. Most of the thunderstorms were occurring in bands in the southern half of Tropical Cyclone Kevin. Bands in the northern half of Kevin consisted primarily of showers and lower clouds.

The size of Tropical Cyclone Kevin’s circulation increased on Saturday. Winds to hurricane/typhoon force extended out 45 miles (75 km) from the center of circulation. Winds to tropical storm force extended out 200 miles (325 km) from the center. The Hurricane Intensity Index (HII) for Tropical Cyclone Kevin was 22.1. The Hurricane Size Index (HSI) was 20.4 and the Hurricane Wind Intensity Size Index (HWISI) was 42.5.

Tropical Cyclone Kevin will move through an environment that is unfavorable for intensification during the next 48 hours. Kevin will move over over water where the Sea Surface Temperatures are near 26˚C. An upper level trough east of Australia will produce northwesterly winds that will blow toward the top of Kevin’s circulation. Those winds will cause strong vertical wind shear during the next 48 hours. The strong vertical wind shear will cause Tropical Cyclone Levin to weaken. Kevin will move over colder water during the next few days. A combination of strong vertical wind shear and colder water will cause Tropical Cyclone Kevin to make a transition to an extratropical cyclone.

The upper level trough east of Australia will steer Tropical Cyclone Kevin toward the east-southeast during the next 48 hours. On its anticipated track Tropical Cyclone Kevin will pass South of Tonga on Sunday.

Tropical Cyclone Kevin Brings Wind and Rain to Southern Vanuatu

Tropical Cyclone Kevin brought wind and rain to southern Vanuatu on Friday morning. At 10:00 a.m. EST on Friday the center of Tropical Cyclone Kevin was located at latitude 19.0°S and longitude 169.2°E which put it about 60 miles (95 km) south-southeast of Port Vila, Vanuatu. Kevin was moving toward the southeast at 15 m.p.h. (24 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 963 mb.

Tropical Cyclone Kevin brought strong winds and locally heavy rain to southern Vanuatu on Friday morning. Kevin was affecting the same area that was hit by Tropical Cyclone Judy earlier this week. Winds to hurricane/typhoon force extended out 50 miles (80 km) from the center of Kevin’s circulation. Winds to tropical storm force extended out 185 miles (300 km) from the center of circulation. The Hurricane Intensity Index (HII) for Tropical Cyclone Kevin was 17.8. The Hurricane Size Index (HSI) was 13.3 and the Hurricane Wind Intensity Size Index (HWISI) was 31.1. Tropical Cyclone Kevin was similar in size and intensity to Tropical Cyclone Judy.

Tropical Cyclone Kevin strengthened as it moved over southern Vanuatu on Friday morning. A circular eye with a diameter of 10 miles (16 km) was at the center of Kevin’s circulation. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Kevin. Storms near the core generated upper level divergence that pumped mass away from the tropical cyclone.

Tropical Cyclone Kevin will move through an environment favorable for intensification during the next 24 hours. Kevin will move over over water where the Sea Surface Temperatures are near 29˚C. An upper level trough east of Australia will produce northwesterly winds that will blow toward the top of Kevin’s circulation. Those winds will cause some vertical wind shear, but the wind shear will not be strong enough to prevent intensification during the rest of today. Tropical Cyclone Kevin is likely to continue to intensify during the next 24 hours. Kevin could strengthen to the equivalent of a major hurricane. The vertical wind shear will increase and Kevin will move over cooler water during the weekend. Tropical Cyclone Kevin will start to weaken when the wind shear increases.

The upper level trough east of Australia will steer Tropical Cyclone Kevin toward the southeast during the next 24 hours. On its anticipated track, the center of Tropical Cyclone Kevin will move away from Port Vila and Efate during the next few hours. Kevin will continue to bring strong winds and locally heavy rain to Port Vila and Efate until it moves farther away. Port Vila and Efate were just hit by Tropical Cyclone Judy. Tropical Cyclone Kevin will hinder efforts to recover from Tropical Cyclone Judy. Tropical Cyclone Kevin will also bring wind and rain to Erromango, Tanna and Aneityum during the next 24 hours. Heavy rain could cause flash floods in some locations.

Elsewhere over the South Pacific Ocean, Tropical Cyclone Judy was making a transition to an extratropical cyclone southwest of Tonga. At 4:00 a.m. EST on Friday the center of Tropical Cyclone Judy was located at latitude 26.5°S and longitude 178.7°W which put it about 460 miles (740 km) southwest of Tonga.
