Tropical Storm Ewiniar Update #9 (FINAL)

Tropical Storm Ewiniar is now fully transitioning into an extra-tropical cyclone as it continues to move across the North Pacific. The system was last located roughly 1,100km northeast of Tokyo. Maximum sustained winds are at 65kph with gusts of up to 85kph. Ewiniar is moving northeastward at 45kph.

Latest satellite image still shows some convective activity. Low-level center continues to get decoupled as strong upper-level winds shear the system apart. We expect Ewiniar to complete the extra-tropical transition later today. It is not forecast to be a threat to land.

Both the Joint Typhoon Warning Center (JTWC) and the Japan Meteorological Agency (JMA) have issued their final warnings on this system. Likewise, this will be our final update on Tropical Storm Ewiniar. We'll have our update on Typhoon Jelawat (nearing the coast of Honshu) later this afternoon.
Issued (0130 UTC) 930am PhT 093012
