Former Tropical Storm Trami strengthened into a typhoon on Saturday night. At 11:00 p.m. EDT on Saturday the center of Typhoon Trami was located at latitude 17.0°N and longitude 134.6°E which put it about 810 miles (1310 km) southeast of Okinawa. Trami was moving toward the west at 12 m.p.h. (19 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. (170 km/h). The minimum surface pressure was 965 mb.
The circulation of Typhoon Trami became more circular and symmetrical on Saturday. An inner band of thunderstorms wrapped most of the way around the center of circulation and eye was developing at the center of Trami. Several bands of showers and thunderstorms were revolving around the core of Typhoon Trami. Storms near the core were generating upper level divergence which was pumping mass away from the typhoon in all directions. Winds to typhoon force extended out about 35 miles (55 km) from the center of circulation. Winds to tropical storm force extended out about 200 miles (320 km) from the center.
Typhoon Trami will move through an environment favorable for intensification during the next several days. Trami will move over water where the Sea Surface Temperature is near 30°C. it will move through a region where the upper level winds are weak and there will be little vertical wind shear. Typhoon Trami could intensify into the equivalent of a major hurricane during the next day or two.
Typhoon Trami will move south of a subtropical ridge over the Western North Pacific Ocean. The ridge will steer Trami toward the west-northwest during the next few days. On its anticipated track Typhoon Trami could be east of Taiwan and southeast of the Ryukyu Islands in four or five days. It could be a powerful typhoon at that time.
