Typhoon Pabuk Update #8

Issued (00 UTC) 8am PhT 092613

Typhoon Pabuk has maintained its intensity as it moves southwest of Mainland Japan. The eye of Pabuk was last located approximately 520km southeast of Tokyo. Maximum sustained winds are at 165kph with gusts of up to 205kph. Typhoon Pabuk is moving northeastward at 30kph.

Latest satellite image shows the eye of Pabuk remaining uniform and still well-defined. Convection has weakened somewhat and it looks like dry air is increasing ahead of the path of the system. Nevertheless, good poleward outflow is helping to sustain the current intensity.

While the strong typhoon-force winds are not going to affect Japan, some areas across Southeastern Honshu (particularly in the Chiba Prefecture) have recorded up to 80kph of sustained winds along with gusts of more than 100kph this morning. Coastal areas are also dealing with high waves being churned by Pabuk. The rain bands, on the other hand, have managed to stay offshore and are not expected to bring any significant precipitation across Honshu.

Typhoon Pabuk will continue moving northeastward and should begin extra-tropical transition today. Increasing wind, decreasing sea surface temperature, and the presence of dry air will lead to weakening over the next 24 to 48 hours. Pabuk is forecast to become completely extra-tropical by Friday and will continue to head northeastward across the North Pacific.

We'll have another update later today.
