western pacific Tropical Storm Etau

[Somerset Squall]

Tropical Storm Etau has formed well south of Japan. Winds are at 35kts according to JMA. Strengthening is expected as Etau heads north along the western periphery of a ridge to the east. As Etau nears Japan, shear and cooler waters will weaken the system. Before this occurs, a 60kt peak is expected (JTWC).

Etau has strengthened to 55kts. The storm is beginning extratropical transition as it moves into Japan. As it becomes further involved with the mid lattitude westerlies, extratropical transition will complete as Etau crosses Japan and noves into the Sea Of Japan.
