Tropical Storm (TS) 13w (wipha) located approximately 195 nm southwest of Shanghai, China, has tracked north-northwestward at 12 knots over the past 06 hours. The storm has weakened significantly over the past 06 hours and will continue to rapidly weaken as it undergoes extratropical transition. The system will accelerate to the north as it becomes fully embedded within the midlatitude flow. Ts 13w will be fully extratropical by tau 12. This is the final warning on this system by the joint typhoon monitored for signs of regeneration.//
