Tropical Storm Khanun brought gusty winds and rain back to Okinawa on Friday night. A weather station at Kadena Air Force Base reported a sustained wind speed of 52 m.p.h. (84 km/h) and a wind gust of 69 m.p.h. (111 km/h). At 11:00 p.m. EDT on Friday the center of Tropical Storm Khanun was located at latitude 27.7°N and longitude 127.2°E which put it about 100 miles (160 km) northwest of Okinawa. Khanun was moving toward the east at 5 m.p.h. (8 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 972 mb.

Former Typhoon Khanun weakened to a tropical storm on Friday. The bands in the inner core of Khanun’s circulation consisted of low clouds and showers. Bands of thunderstorms were located in the eastern and southern parts of Tropical Storm Khanun. Bands in the northwestern part of Khanun also consisted primarily of showers and lower clouds. The bands of thunderstorms generated upper level divergence that pumped mass away to the east of the tropical storm. Winds to tropical storm force extended out 200 miles (325 km) from the center of Khanun’s circulation.

Tropical Storm Khanun will move through an environment that will be somewhat favorable for intensification during the next 24 hours . Khanun will move over water where the Sea Surface Temperatures are near 28˚C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. However, Tropical Storm Khanun is unlikely to intensify during the next 24 hours, because of the lack of thunderstorms in the inner core of its circulation. The large circulation around Tropical Storm Khanun seems to be in an equilibrium with its environment and the intensity may not change much during the next 36 hours..

Tropical Storm Khanun will move around the northwestern part of a subtropical high pressure system over the Western North Pacific Ocean. The high pressure system will steer Khanun toward the east during the next 24 hours. On its anticipated track, the center of Tropical Storm Khanun will pass north of Okinawa in 12 hours. The center of Khanun could pass over Amami Oshima in less than 24 hours. Tropical Storm Khanun will continue to produce strong, gusty winds and locally heavy rain in Okinawa, Amami Oshima and the other northern Ryukyu Islands. Heavy rain will cause flash floods in some locations.
