Tropical Storm Yagi Update #7

Issued (01 UTC) 9am PhT 061113

Tropical Storm Yagi has now moved away from the Philippine Area of Responsibility and is racing quickly towards Japan. The storm was last located approximately 860km east northeast of Okinawa. Maximum sustained winds have increased to 95kph with gusts of up to 120kph. TS Yagi is currently moving northward at 30kph.

Latest satellite image shows Yagi looking a little bit better compared to yesterday. Banding has improved and the circulation center is well-defined as well. There is still some impinging on the western half of the storm but overall, Yagi looks more symmetrical. This intensification is short-lived, however, as the system will soon be moving into less-favorable region with increasing vertical wind shear and cooler sea surface temperatures.

As we've said in our previous update this morning, we no longer think Yagi will make landfall in Japan. Instead, it will move near the southern coast but will significantly slow down and will make a u-turn away from Honshu. Nevertheless, we still expect some light rains, breezy conditions, and rough surf to impact the Japanese coast beginning today and will last into Thursday. By then, we expect Yagi to weaken to a Tropical Depression.

We'll have another update later tonight.
