Typhoon Vamco brought wind and rain to Vietnam on Saturday night. At 10:00 p.m. EST on Saturday the center of Typhoon Vamco was located at latitude 17.3°N and longitude 107.5°E which put it about 40 miles (65 km) east of Vinh Linh, Vietnam. Vamco was moving toward the northwest at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 115 m.p.h. (185 km/h). The minimum surface pressure was 979 mb.

The center of Typhoon Vamco was about to make landfall on the coast of Vietnam between Vinh Linh and Dong Hoi on Saturday night. Bands on the western side of Vamco were already bringing wind and rain to Vietnam. A flow of drier air from eastern Asia into the western part of the circulation around Vamco caused the typhoon to weaken as it approached Vietnam. Even though it was weaker, Typhoon Vamco was still capable of causing serious damage. Winds to typhoon force extended out 30 miles (50 km) from the center of Vamco. Winds to tropical storm force extended out 130 miles (210 km from the center.

Typhoon Vamco will bring strong winds to the coast of central Vietnam during the next few hours. Wind blowing water toward the coast will cause a storm surge north of Vinh Linh. The winds blwoing around Vamco will weaken when it moves inland. However, Typhoon Vamco will drop heavy rain over parts of central Vietnam, southern Laos and northeastern Thailand. Heavy rain will fall on saturated ground and significant flooding is likely to occur.
