Tropical Storm Nakri Update #1

Issued (11 UTC) 7pm PhT 073114

Tropical Storm Nakri is a monsoon depression that has been spinning across the Philippine Sea over the past 2 days. The Japan Meteorological Agency and other agencies in the region, with the exception of the Joint Typhoon Warning Center, are giving warnings and bulletins on this system. Nakri was last located approximately 100km southwest of Okinawa. Maximum sustained winds are at 75kph with gusts of up to 95kph. TS Nakri is moving north northwestward at 20kph.

Nakri, being a monsoon depression, has a very large circulation and an expansive wind field. The system also has very little convection near the circulation center. Its strong winds can be felt as far as 400km away from the center. Due to its large nature, Nakri isn't really intensifying that quickly despite the favorable conditions in the region.

Latest radar out of Okinawa shows scattered light rain showers. Much of the convection is still located south of the circulation and should impact the Japanese Islands by tomorrow. For the latest radar images and cyclone information from Japan, please click HERE (JMA Website)

Tropical Storm Nakri will continue moving generally northward into the East China Sea. We expect very little intensification but its large circulation will affect parts of Eastern China and Ryukyu Islands. By early next week, the system could move into the Korean Peninsula bringing rains and strong winds in the region.

We'll have another update tomorrow.
