Tropical Storm Wukong (27W) by Philippines12.5N 126.7E
Tropical Storm Wukong (27W) located approximately 285 nm south-southwest of Manila, Philippines, has tracked west-southwestward at 14 knots over the past six hours. Here, the system can be seen encroaching on the Philippines, whose borders are visible despite the convection covering them due to the use of the Chelys Satellite Rapid Response System (SRRS) “borders” feature.
Animated enhanced infrared satellite imagery shows the low level circulation center has become fully exposed and ragged as the main convection was sheared almost 200 nm to the north. The same animation shows the convective tops have significantly warmed as the bands unraveled and dispersed. Maximum significant wave height is 11 feet.
Upper level analysis indicates the system is 05 degrees south of the ridge axis in an area of moderate to strong (20-30 knot) southerly vertical wind shear (VWS). The cyclone is tracking along the southern extension of a deep-layered subtropical ridge to the north. The system is expected to dissipate in 12 hours due to the high VWS, exacerbated by a cold northeasterly surface wind surge in the South China Sea.
