Tropical Storm Yagi Update #8

Issued (1330 UTC) 930pm PhT 061113

Tropical Storm Yagi is starting to weaken as it moves into hostile environment. The storm was last located approximately 660km south southeast of Tokyo, Japan. Maximum sustained winds are slightly down to 85kph with gusts of up to 110kph. TS Yagi is moving northward at 30kph.

Latest satellite image shows that the convective activity has significantly decreased over the past 24 hours. Furthermore, we continue to see impinging on the western periphery and the whole system itself is starting to look asymmetrical.

As we’ve been saying over the past two updates, we no longer think Yagi will make landfall in Japan. Instead, the storm is forecast to significantly slow down today just south of the Kii Peninsula. The sub-tropical ridge will, then, steer the system slowly to the east parallel to the Honshu coast. While landfall is no longer in the forecast, the southern coasts of Kinki, Chubu, and even Kanto Regions could still see some light rains, breezy conditions, and high waves along the shore. Yagi is also forecast to continue weakening and could become a Tropical Depression by as early as tomorrow morning (Wednesday).
We’ll have another update tomorrow.
