Tropical Cyclone Dovi Intensifies to Equivalent of Hurricane/Typhoon

Tropical Cyclone Dovi intensified to the equivalent of a hurricane/typhoon near the southern end of New Caledonia on Thursday morning. At 10:00 a.m. EST on Thursday the center of Tropical Cyclone Dovi was located at latitude 23.6°S and longitude 166.7°E which put it about 80 miles (130 km) southeast of Noumea, New Caledonia. Dovi was moving toward the southwest at 14 m.p.h. (22 km/h). The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 100 m.p.h. (160 km/h). The minimum surface pressure was 969 mb.

Tropical Cyclone Dovi strengthened to the equivalent of a hurricane/typhoon near the southern end of New Caledonia on Thursday morning. An eye with a diameter of 50 miles (80 km) formed at the center of Dovi’s circulation. The eye of Tropical Cyclone Dovi passed over the Ile des Pins. The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the center of Dovi’s circulation. Winds to hurricane/typhoon force extended out 25 miles (40 km) to the east of the center of Tropical Cyclone Dovi. Winds to tropical storm force extended out 150 miles (240 km) from the center of circulation.

Tropical Cyclone Dovi will move around the western end of a high pressure system over the South Pacific Ocean. The high pressure system will steer Dovi toward the south during the next several days. On its anticipated track Tropical Cyclone Dovi will move away from southern New Caledonia. Dovi will continue to cause strong winds and locally heavy rain over southern New Caledonia during the next few hours. Locally heavy rain could cause flash floods in some locations. Weather conditions should improve in New Caledonia when Tropical Cyclone Dovi moves farther away. Dovi could approach New Zealand during the weekend as a strong extratropical cyclone.

Tropical Cyclone Dovi will move through an environment favorable for intensification during the next 12 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 is likely to intensify during the next 12 hours. Dovi will move into a region where the Sea Surface Temperatures are colder and where there will be more vertical wind shear during the weekend. The combination of colder water and more wind shear will cause Tropical Cyclone Dovi to make a transition to a strong extratropical cyclone.
