Tropical Storm Etau Nears Vietnam, Vamco Threatens Philippines

Tropical Storm Etau neared Vietnam on Monday and newly formed Tropical Storm Vamco threatened the Philippines. At 4:00 a.m. EST on Monday the center of Tropical Storm Etau was located at latitude 12.8°N and longitude 111.6°E which put it about 170 miles (280 km) east of Tuy Hoa, Vietnam. Etau was moving toward the west at 15 m.p.h. (24 km/h). The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h). The minimum surface pressure was 995 mb.

The distribution of thunderstorms around Tropical Storm Etau was asymmetrical. Etau was moving under the southern part of an upper level ridge over eastern Asia. The ridge was producing easterly winds which were blowing toward the top of Etau. Those winds were causing moderate vertical wind shear. The shear was causing the stronger thunderstorms to occur in bands on the western side of Tropical Storm Etau. The bands in the eastern side of Etau consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 150 miles (240 km) in the northern half of Tropical Storm Etau. Winds to tropical storm force only extended out 50 miles in the southern half of Etau.

Tropical Storm Etau will move south of a high pressure system over eastern Asia. The high will steer Etau toward the west during the next two days. On its anticipated track the center of Etau will make landfall in Vietnam near Tuy Hoa in about 12 hours.

Tropical Storm Etau will move through an environment that should allow it to maintain its intensity until it makes landfall in Vietnam. Etau will move over water where the Sea Surface Temperature is near 28°C. The upper level ridge over eastern Asia will continue to cause moderate vertical wind shear which will limit intensification.

Since the stronger thunderstorms are in the western half of Tropical Storm Etau, heavy rain will fall over central Vietnam before the center of Etau makes landfall. Etau will drop locally heavy rain over central Vietnam, northern Cambodia, southern Laos and northeastern Thailand. The ground is already saturated in that region and flash floods are likely.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Vamco developed east of the Philippines. At 4:00 a.m. EST on Monday the center of Tropical Storm Vamco was located at latitude 12.8°N and longitude 130.6°E which put it about 370 miles (605 km) east of Laoang, Philippines. Vamco was moving toward the northwest at 13 m.p.h. (20 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 1002 mb. Tropical Storm Vamco is forecast to move toward Luzon and to strengthen into a typhoon.

Tropical Storm Nakri Brings Wind, Rain to Vietnam and Cambodia

Tropical Storm Nakri brought wind and rain to Vietnam and Cambodia on Sunday.  At 4:00 p.m. EST on Sunday the center of Tropical Storm Nakri was located at latitude 13.0°N and longitude 108.9°E which put it about 20 miles (35 km) west of Tuy Hoa, Vietnam.  Nakri was moving toward the west at 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h).  The minimum surface pressure was 992 mb.

The center of Tropical Storm Nakri made landfall on the coast of Vietnam near Tuy Hoa on Sunday.  The maximum sustained wind speed at the time of landfall was 65 m.p.h. (105 km/h).  Nakri moved slowly toward the west after it made landfall.  Tropical Storm Nakri has been weakening slowly since the center moved over land.  The heaviest rain was falling in bands in the western half of the circulation.  Heavy rain was falling over portions of southern Vietnam and northeastern Cambodia.  The strongest winds were occurring in the eastern half of Nakri which was still over the South China Sea.  Winds to tropical storm force extended out 60 miles (95 km) from the center of circulation.

Tropical Storm Nakri will move south of a ridge over high pressure over the South China Sea and southeast Asia.  The ridge will steer Nakri toward the west-northwest during the next 24 to 36 hours.  Tropical Storm Nakri will continue to weaken as it moves farther inland.  On its anticipated track Nakri will drop locally heavy rain over parts of southern Vietnam, northern Cambodia, southern Laos and eastern Thailand.  Heavy rain could cause flash floods in some locations.
