The system was last located approximately 400km southeast of Sapporo or about 630km northeast of Tokyo. Maximum sustained winds are at 65pkh with gusts of up to 85kph. TS Vongfong is moving northeastward at 70kph.

Latest satellite image shows Vongfong is nearing the extra-tropical transition. Convection is asymmetrical, circulation center has elongated, and frontal boundaries have begun to develop. Wind speeds of up to 80kph are still being reported especially along the coast of Hokkaido but that should weaken later today.

Vongfong will continue moving quickly to the northeast today as a mid-latitude cyclone. The remaining rains in Northern Honshu and Hokkaido should end later today as the system moves into the North Pacific.

This is our Final Update for Tropical Storm Vongfong. There are no other tropical cyclones in the Western Pacific as of this time.
