Tropical Storm Co-may neared the coast of eastern China on Tuesday.  At 11:00 a.m. EDT on Tuesday the center of Tropical Storm Co-may was located at latitude 28.9°N and longitude 123.1°E which put the center about 215 miles (345 km) south-southeast of Shanghai, China.  Co-may was moving toward the northwest at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 982 mb.

After meandering around Okinawa for several days Tropical Storm Co-may started to move toward the coast of eastern China south of Shanghai on Tuesday.  The distribution of thunderstorms in Tropical Storm Co-may was asymmetrical.  Thunderstorms were occurring in bands in the northern and western parts of Co-may’s circulation.  Bands in the eastern and southern parts of Tropical Storm Co-may consisted primarily of showers and lower clouds.

The distribution of wind speeds in Tropical Storm Co-may was also asymmetrical.  Winds to tropical storm force extended out 175 miles (280 km) in the northern side of Co-may’s circulation.  The winds in the southern half of Tropical Storm Co-may were blowing at less than tropical storm force.

Tropical Storm Co-may will move through an environment somewhat favorable for intensification during then ext 12 hours.  Co-may will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the eastern side of an upper level trough that is over eastern Asia.  The upper level trough will produce southwesterly winds that will blow toward the top of Co-may’s circulation.  Those winds will cause some vertical wind shear.  The vertical wind shear will inhibit intensification but the wind shear may not be enough to prevent intensification.  Tropical Storm Co-may could intensify during the next 12 hours.

Tropical Storm Co-may will move around the western end of a high pressure system over Japan.  The high pressure system will steer Co-may toward the northwest during the next 24 hours.  On its anticipated track, the center of Tropical Storm Co-may will be near Shanghai in less than 24 hours.

Tropical Storm Co-may will bring wind and rain to the region around Shanghai.  Heavy rain could cause floods in Zhejiang and Jiangsu.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Krosa was meandering south of Japan.  At 11:00 a.m. EDT on Tuesday the center of Tropical Storm Krosa was located at latitude 28.6°N and longitude 142.9°E which put the center about 500 miles (805 km) south-southeast of Tokyo, Japan.  Krosa was moving toward the north at 2 m.p.h. (3 km/h).  The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h).  The minimum surface pressure was 980 mb.
