Tropical Storm Leepi Morning Update and a new Tropical Depression

Tropical Storm Leepi continues to affect the Miyako Islands of Japan. The storm has also left the Philippine Area of Responsibility earlier this morning. TS Leepi was last located approximately 120km north northwest of Miyako-jima or about 300km west southwest of Okinawa. Maximum sustained winds are at 65kph with gusts of up to 85kph. TS Leepi is moving northward at 25kph.

Latest visible satellite image shows that Leepi is starting to feel the effects of the increase in wind shear. Convective activity is now more confined on the southern semi-circle with the low-level center becoming slightly exposed. We are also seeing multiple vortices forming and rotating around Leepi’s true center.

Leepi moved near the Miyako Islands earlier this morning bringing gusty winds and moderate rains. Many stations in the islands have reported seeing winds of up to 100kph along with rainfall amounts of 50 to even 80mm. Most of the bands are now moving away from Miyako although residual rains may still impact the region. Meanwhile, Okinawa should start seeing isolated rain showers beginning this afternoon.

Tropical Storm Leepi will move just west of Okinawa later this afternoon. The system is forecast to start accelerating and turning more to the northeast as it rounds the sub-tropical ridge. Leepi is also forecast to move very near the Kyushu Island by Friday morning. By then, the system should begin transitioning into an extra-tropical cyclone as it interacts with the baroclinic zone.

Meanwhile, a new Tropical Depression has been classified by the Japan Meteorological Agency. This new system is located in the South China Sea, just west of the Philippine Islands. This system (also classified as Invest 94W by the NRLMRY) is exhibiting strong convective activity and an improving curved banding near the center. JMA expects it to become a Tropical Storm within 24 hours while the Joint Typhoon Warning Center (JTWC) has upgraded the system’s chance to MEDIUM.
