Tropical Cyclone Tonga passed west of Tonga on Friday. At 4:00 p.m. EST on Friday the center of Tropical Cyclone Yasa was located at latitude 20.6°S and longitude 178.0°W which put it about 280 miles (305 km) west of Nuku’Alofa, Tonga. Yasa was moving toward the south at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h). The minimum surface pressure was 974 mb.

After making a direct hit on Vanua Levu, Tropical Cyclone Yasa moved over the Fiji islands in the Lau Group. There were reports of damage and casualties from Fiji. Tropical Cyclone Yasa weakened after it made landfall on Vanua Levu. The eye and eyewall were disrupted by passage over land. An upper level low centered north of New Zealand produced northerly winds which blew toward the top of Yasa’s circulation on Friday. Those winds caused moderate vertical wind shear and the shear caused the tropical cyclone to weaken steadily on Friday.

The circulation around Tropical Cyclone Yasa exhibited less organization on Friday. The strongest thunderstorms were occurring in a band in the southern half of the circulation. Bands in the northern half of Yasa consisted primarily of showers and lower clouds. The circulation around Tropical Cyclone Yasa was still large. Winds to tropical storm force extended out 200 miles (320 km) from the center of circulation.

Tropical Cyclone Yasa will move through an environment that is mostly unfavorable for intensification during the next several days. Yasa will move over water where the Sea Surface Temperature is near 27°C. However, the upper level low centered north of New Zealand will continue to cause moderate vertical wind shear. The shear is likely to be strong enough to cause Tropical Cyclone Yasa to continue to weaken.

Tropical Cyclone Yasa will move around the eastern side of the upper level low. The low will steer Yasa toward the southwest during the next 48 hours. On its anticipated track Tropical Cyclone Yasa will pass west of Tonga and it will remain north of New Zealand.
