Tropical Storm Nakri moved away from Japan on Monday.  At 5:00 p.m. EDT on Monday the center of Tropical Storm Nakri was located at latitude 34.3°N and longitude 149.1°E which put the center about 460 miles (740 km) east of Tokyo, Japan.  Nakri was moving toward the east at 23 m.p.h. (37 km/h).  The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h).  The minimum surface pressure was 985 mb.

Former Typhoon Nakri weakened back to a tropical storm on Monday as it quickly moved farther away from Japan.  Nakri was still a very well organized tropical storm.  The inner end of a rainband wrapped most of the way around the center of Nakri’s circulation.  Bands of showers and thunderstorms revolved around the center of Tropical Storm Nakri.  Storms near the center of Nakri generated upper level divergence that pumped mass away to the east of the tropical storm.

The distribution of winds speeds around Tropical Storm Nakri was fairly symmetrical.  Winds to tropical storm force extended out 155 miles (250 km) from the center of Nakri’s circulation.

Tropical Storm Nakri will move through an environment that will be unfavorable for intensification of a tropical cyclone during the next 24 hours.  Nakri will move over water where the Sea Surface Temperatures are near 25°C.  It will move under the southeastern part of an upper level trough that is over northern Japan.  The upper level trough will produce westerly winds that will blow toward the top of Nakri’s circulation.  Those winds will cause strong vertical wind shear.  Cooler Sea Surface Temperatures and strong vertical wind shear will cause Tropical Storm Nakri to weaken during the next 24 hours.  The cooler Sea Surface Temperatures and strong vertical wind shear will also cause Nakri to make a transition to an extratropical cyclone.

The upper level trough over northern Japan will steer Tropical Storm Nakri quickly toward the east during the next 24 hours.  On its anticipated track, Tropical Storm Nakri will continue to move quickly away from Japan.
