Tropical storm Hagupit had weakened to a tropical depression when it arrived at the south central coast of Viet Nam on early Friday, bringing torrential rain to the region, the Viet Nam National Center for Hydro-Meteorological Forecasting reported.

The tropical depression entered the coast of Khanh Hoa and Ninh Thuan provinces early this morning, December 12, and then weakened into a low pressure area, packing winds of less than 39 kph.

In the next 12 hours, the low pressure system will move west-southwest rapidly and dissipate, the center said.
