TS Sanvu Update #13 (FINAL)

Tropical Storm Sanvu is now undergoing extra-tropical transition over the North Pacific. It was last located approximately 550km east northeast of Chichi-Jima. Maximum sustained winds are now down to 85kph gusting to 100kph. TS Sanvu is currently moving east northeastward at 30kph.

Satellite images continue to show convective activity on the eastern half of the storm; banding continues to be present on microwave images as well. Nevertheless, it is clear Sanvu is now beginning to transition into an extra-tropical storm as it begins to interact with the baroclinic zone. It is forecast to complete the transition early tomorrow (Monday).

Due to the weakening and expected transition to an extra-tropical storm, this will be our final update on TS Sanvu. Rest of the Pacific looks quiet right now although some computer models are hinting at a possible development later next week. We'll have a tropical update tomorrow to discuss this possibility.
