Tropical Cyclone Gita strengthened on Saturday as it passed just to the east of Niue. Outer rainbands on the western side of Gita were bringing gusty winds and heavy rain to Niue. At 4:00 p.m. EST on Saturday the center of Tropical Cyclone Gita was located at latitude 19.2°S and longitude 168.8°W which put it about 85 miles (135 km) east-southeast of Niue. Gita was moving toward the south at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 105 m.p.h. (165 km/h). The minimum surface pressure was 969 mb. Tropical Cyclone Gita was the equivalent of a hurricane/typhoon.
The circulation of Tropical Cyclone Gita became more symmetrical on Saturday. Several rainbands wrapped completely around the center of circulation. A clear area appeared at the center of circulation on visible satellite images, which indicated that an eye was forming. A ring of strong thunderstorms surrounded the eye and the strongest winds were occurring in the ring. Storms in the core of the circulation were generating upper level divergence which was pumping mass away from the tropical cyclone. Other rainbands were revolving around the core of Tropical Cyclone Gita.
Tropical Cyclone Gita will move through an area favorable for intensification during the next 24 to 48 hours. Gita will move over water where the Sea Surface Temperature is near 30°C. Tropical Cyclone Gita is moving around the eastern end of an upper level low, but the upper level winds are weak and there is not much vertical wind shear. There is drier air to the southwest of Gita, but it does not seem to be entering the circulation of the tropical cyclone. Tropical Cyclone Gita will continue to intensify and it could strengthen rapidly. Gita could strengthen into the equivalent of a major hurricane.
The upper level low is steering Tropical Cyclone Gita toward the south. Gita will turn toward the southeast in about 12 to 24 hours. When Gita reaches the southern side of the upper low, it will move toward the west. On its anticipated track Tropical Cyclone Gita will pass just to the southeast of Niue. Gita could approach Tonga in about 36 hours and it could the equivalent of a major hurricane at that time.
