Tropical Storm Talim formed over the South China Sea during Friday night. At 5:00 a.m. EDT on Saturday the center of Tropical Storm Talim was located at latitude 18.2°N and longitude 117.7°E which put it about 360 miles (585 km) southeast of Hong Kong. Talim was moving toward the northwest at 5 m.p.h. (8 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 992 mb.

A large low pressure system over the South China Sea strengthened during Friday night and the Japan Meteorological Agency designated the system as Tropical Storm Talim. The circulation around Tropical Storm Talim was very large. Winds to tropical storm force extended out 200 miles (320 km) in the northwestern quadrant of Talim’s circulation. Winds to tropical storm force extended out 90 miles (145 km) in the eastern side of the circulation. Even though the circulation around Tropical Storm Talim was large, the winds were weaker near the center of circulation. There were few thunderstorms near the center of circulation. Thunderstorms were occurring in bands in the northern and southern sides of Tropical Storm Talim.

Tropical Storm Talim will move through an environment somewhat favorable for intensification during the next 24 hours. The water at the surface of the South China Sea is very warm. Talim will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the southern side of an upper level ridge that extends from the Western North Pacific Ocean to China. The ridge will produce easterly winds that will blow toward the top of Talim’s circulation. Those winds will cause moderate vertical wind shear and the shear will inhibit intensification. Tropical Storm Talim is likely to intensify during the next 24 hours in spite of the vertical wind shear.

Tropical Storm Talim will move around the southwestern part of a subtropical high pressure system over the Western North Pacific Ocean. The high pressure system will steer Talim toward the northwest during the weekend. On its anticipated track Tropical Storm Talim could be south of Hong Kong in less than 48 hours. Talim could approach the coast of southern China early next week. Tropical Storm Talim could be a typhoon when it approaches southern China.
