Tropical storm 04W (Leepi) remains active over the east China Sea…located approximately 282 NM southwest of Sasebo, Japan. This TS has tracked north-northeast at 12 knots (14 mph) over the past six hours. Satellite imagery shows well defined shallow banding wrapping into the low level circulation center. The Joint Typhoon Warning Center (JTWC) reports that the initial intensity is 35 knots (40 mph). TS Leepi remains within an unfavorable environment, characterized by moderate vertical wind shear, and marginal sea surface temperatures.

TS 04W is forecast to remain on a more or less north-northeast bearing, and then turn more towards the east, and accelerate…as it begins to encounter the prevailing westerly wind flow. It will lose its tropical character within 12 hours, and become a cold core system by 36 hours. The JTWC forecast path takes this system over the southern Japanese Islands, although for only a short time. It will then move back over the ocean, as it parallels the southern coasts of the rest of the islands…offshore. It will move by just south of Sasebo, and then a bit further south of Iwakuni, Kyoto, and finally Tokyo. Gusty breezes, and locally heavy rainfall will occur over these islands as it moves by.

Tropical cyclone 05W has recently formed in the South China Sea…located approximately 403 NM south-southeast of Hong Kong. Satellite imagery shows a slowly consolidating low level circulation center…with improved curved banding. The initial intensity provided by the JTWC is at 25 knots (29 mph). TD 05W is located within an unfavorable environment, characterized by moderate to strong vertical wind shear.

This tropical system is forecast to move more or less northwestward, and then take a more west-northwestward track over the next 24 hours. The JTWC suggests that this system may strengthen slightly, becoming a minimal tropical storm. This tropical cyclone is expected to make landfall over southeast China in about 72 hours…and then track into north Vietnam and dissipate over land thereafter.
