Tropical Storm Toraji Update #2

Issued (2230 UTC) 630am PhT 090213

Tropical Storm Toraji continues to slowly move across the East China Sea. The storm center was last located approximately 200km north northwest of Okinawa. Maximum sustained winds are around 75kph with gusts of up to 95kph. TS Toraji is moving northeastward at 10kph.

Latest satellite image continue to show good convection with banding wrapping around the circulation center of Toraji. Convection is slightly better on the northern periphery with drier air trying to wrap around the southern half of the storm. Poleward outflow remains excellent as well, aided by the mid-latitude trough situated to the north of Toraji.

Lines of light to moderate rains continue to impact the Ryukyu Islands particularly Amami where up to 50mm of rain is possible this morning. The majority of the heavy rains remains offshore and so we are not expecting widespread reports of heavy rains in the Ryukyus. However, as Toraji makes landfall in Kyushu later this week, there could be up to 200mm of rain falling in the region. For the latest radar images and forecasts from Japan, click HERE (JMA Website)

Tropical Storm Toraji is forecast to slightly intensify in the next two days as upper-level conditions remain conducive. It is also expected to make landfall in the island of Kyushu by early Thursday morning possibly as a transitioning extra-tropical cyclone. Heavy rains will spread not only across Kyushu but also to parts of Western Honshu and Shikoku.

We'll have another update later today.
