Tropical Cyclone Dovi Strengthens near Loyalty Islands

Tropical Cyclone Dovi strengthened near the Loyalty Islands on Wednesday night. At 10:00 p.m. EST on Wednesday the center of Tropical Cyclone Dovi was located at latitude 21.5°S and longitude 168.3°E which put it about 170 miles (280 km) east-northeast of Noumea, New Caledonia. Dovi was moving toward the south-southwest at 11 m.p.h. (17 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.

The center of Tropical Cyclone Dovi was located just to the northeast of the island of Mare in the Loyalty Islands. The inner end of a rainband wrapped around the northern and eastern sides of the center of Dovi. The rainband had not yet wrapped around the southern and western sides of the center of circulation. The strongest thunderstorms were occurring in bands in the northern half of Tropical Cyclone Dovi. Bands in the southern half of Dovi’s circulation consisted primarily of showers and lower clouds. 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 155 miles (250 km) from the center of Tropical Cyclone Dovi.

Tropical Cyclone Dovi will move through an environment favorable for intensification during the next 24 hours. Dovi will move over water where the Sea Surface Temperatures are near 28˚C. It will move under the western part of an upper level ridge centered east of New Caledonia. The ridge will produce southerly winds that will blow toward the top of the tropical cyclone. Those winds will cause some vertical wind shear. The wind shear will inhibit intensification, but it will not be strong enough to prevent intensification. Tropical Cyclone Dovi will intensify during the next 24 hours. Dovi could strengthen to the equivalent of a hurricane/typhoon during the next day or so.

Tropical Cyclone Dovi will move around the western side of a high pressure system over the South Pacific Ocean. The high pressure system will steer Dovi toward the southwest during the next 24 hours. On its anticipated track Tropical Cyclone Dovi will move near the southern end of New Caledonia during the next 12 hours. Dovi will bring gusty winds and locally heavy rain to the Loyalty Islands including Ouvea, Lifou and Mare. The center of Tropical Cyclone Dovi could be near Ile des Pins in 12 hours. Dovi will begin to affect southern New Caledonia during the next 12 hours. Tropical Cyclone Dovi could be the equivalent of a hurricane/typhoon when it moves near the southern end of New Caledonia. Dovi will bring strong winds and locally heavy rain. Heavy rain could cause flash floods in some locations.

Tropical Cyclone Dovi Brings Wind and Rain to Vanuatu

Tropical Cyclone Dovi brought wind and rain to parts of Vanuatu on Wednesday morning. At 10:00 a.m. EST on Wednesday the center of Tropical Cyclone Dovi was located at latitude 20.5°S and longitude 169.4°E which put it about 260 miles (420 km) east-northeast of Noumea, New Caledonia. Dovi was moving toward the southeast at 6 m.p.h. (10 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 Dovi brought gusty winds and rain to southern Vanuatu on Wednesday morning. The center of Dovi’s circulation was southwest of Aneityum. Bands on the northern side of Tropical Cyclone Dovi also brought wind and rain to Erromango and Tanna. The inner end of a rainband wrapped around the center of Dovi’s circulation, which could represent the initial stage in the formation of an eyewall. Most of the thunderstorms and the strongest winds were occurring in bands in the northern half of Tropical Cyclone Dovi. Bands in the southern half of the circulation consisted primarily of showers and lower clouds. Storms near the center generated upper level divergence that pumped mass away from the tropical cyclone. Winds to tropical storm force extended out 175 miles (280 km) in the northern half of Dovi’s circulation. Winds to tropical storm force extended out 70 miles (110 km) in the southern half of the circulation.

Tropical Cyclone Dovi will move through an environment favorable for intensification during the next 24 hours. Dovi will move over water where the Sea Surface Temperatures are near 28˚C. It will move under the western part of an upper level ridge centered east of New Caledonia. The ridge will produce southerly winds that will blow toward the top of the tropical cyclone. Those winds will some moderate vertical wind shear. The wind shear will inhibit intensification, but it will not be strong enough to prevent intensification. Tropical Cyclone Dovi will intensify during the next 24 hours and it could strengthen rapidly if an inner core with an eye and an eyewall devlops.

Tropical Cyclone Dovi will move around the western side of a high pressure system over the South Pacific Ocean. The high pressure system will steer Dovi toward the southwest during the next 24 hours. On its anticipated track Tropical Cyclone Dovi will move slowly away from Vanuatu. Weather conditions will gradually improve as Dovi moves away. Tropical Cyclone Dovi will be near the Loyalty Islands in 12 hours. The center could pass near Mare. Dovi will bring gusty winds and locally heavy rain to Ouvea, Lifou and Mare. The center of Tropical Cyclone Dovi could be near Ile des Pins in 24 hours. Dovi will begin to affect southern New Caledonia during the next 24 hours.

Tropical Cyclone Forms near Vanuatu

Tropical Cyclone 11P formed near Vanuatu on Tuesday night. At 10:00 p.m. EST on Tuesday the center of Tropical Cyclone 11P was located at latitude 19.8°S and longitude 168.9°E which put it about 235 miles (380 km) northeast of Noumea, New Caledonia. Tropical Cyclone 11P was moving toward the south-southeast at 4 m.p.h. (6 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 994 mb.

A low pressure system near the island of Tanna strengthened to a tropical cyclone on Tuesday night. More thunderstorms developed in bands in the western half of Tropical Cyclone 11P. Bands in the eastern half of the circulation consisted primarily of showers and low clouds. Storms near the center of circulation began to generate upper level divergence that pumped mass away to the west of the tropical cyclone. Winds to tropical storm force extended out 75 miles (120 km) from the center of circulation.

Tropical Cyclone 11P will move through an environment favorable for intensification during the next 24 hours. Tropical Cyclone 11P will move over water where the Sea Surface Temperatures are near 28˚C. It will move under the northern part of an upper level ridge centered east of New Caledonia. The ridge will produce southeasterly winds that will blow toward the top of the tropical cyclone. Those winds will cause moderate vertical wind shear. The wind shear will inhibit intensification, but it will not be strong enough to prevent intensification. Tropical Cyclone 11P is likely to intensify during the next 24 hours.

Tropical Cyclone 11P will move around the western side of a high pressure system over the South Pacific Ocean. The high pressure system will steer the tropical cyclone toward the south-southwest during the next 24 hours. On its anticipated track Tropical Cyclone 11P will move slowly away from Vanuatu. The tropical cyclone will be near the Loyalty Islands in 24 hours. The center could pass near Mare. Tropical Cyclone 11P will bring gusty winds and locally heavy rain to Ouvea, Lifou and Mare. The center of Tropical Cyclone could reach southern New Caledonia within 36 hours.
