A distinct low level center of circulation developed in an area of thunderstorms over the South China Sea east of southern Vietnam on Saturday and the Japan Meteorological Agency designated the system as Tropical Storm Teraji. The circulation around Teraji was exhibiting evidence of vertical wind shear. The center of circulation was on the eastern edge of a cluster of thunderstorms. Tropical Storm Teraji was south of an upper level ridge. The ridge was producing easterly winds which were causing moderate vertical wind shear. The stronger thunderstorms were occurring in bands west of the center of circulation, which was likely an effect of the wind shear.
The ridge north of Tropical Storm Teraji will steer the tropical storm westward into southern Vietnam. On its anticipated track Teraji will move over southern Vietnam on Sunday. Tropical Storm Teraji will move across southern Cambodia early next week. Thunderstorms in rainbands in the western half of Teraji could drop locally heavy and floods could occur in some locations.
