Tropical Storm Nuri developed over the South China Sea on Friday.  At 5:00 p.m. EDT on Friday the center of Tropical Storm Nuri was located at latitude 18.1°N and longitude 116.4°E which put it about 360 miles (580 km) south-southeast of Hong Kong.  Nuri was moving toward the west-northwest at 12 m.p.h. (19 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 998 mb.

The wind speed around former Tropical Depression 02W increased on Friday and the Japan Meteorological Agency designated the system as Tropical Storm Nuri.  The distribution of thunderstorms around Nuri was asymmetrical.  The strongest thunderstorms were occurring in bands in the southern and western parts of the circulation.  Bands in the eastern and northern portions of Tropical Storm Nuri consisted primarily of showers and lower clouds.  Thunderstorms near the center of Nuri began to generate upper level divergence which pumped mass away from the tropical storm.

Tropical Storm Nuri will move through an environment somewhat favorable for intensification during the next 24 hours.  Nuri will move over water where the Sea Surface Temperature is near 30°C.  It will move under the southwestern part of an upper level ridge centered over eastern China.  The ridge will produce northeasterly winds which will blow toward the top of the circulation.  Those winds will cause some vertical wind shear and the shear will inhibit intensification.  The wind shear could also cause the distribution of thunderstorms to remain asymmetrical.  Tropical Storm Nuri is likely to get stronger during the next 24 hours in spite of the vertical wind shear.

Tropical Storm Nuri will move around the southwestern part of a subtropical high pressure system over the Western North Pacific Ocean.  The high will steer Nuri toward the northwest during the next 24 to 36 hours.  On its anticipated track the center of Tropical Storm Nuri will approach the coast of China southwest of Hong Kong in about 24 hours.  Nuri will drop locally heavy rain over parts of southeastern China.
