Tropical Rainstorm Vamco will bring flooding rain to portions of Indochina through at least Wednesday.
As of Monday evening local time, 215 mm (8 inches) of rain from Vamco has been reported in Da Nang, Vietnam, before making landfall south of the city as a tropical storm. Wind gusts up to 70 km/h (45 mph) were reported in the city as well.
The tropical cyclone will quickly weaken across the mountainous terrain of Vietnam and Laos Monday night local time, but flooding will persist in the region.

Heavy rain will press south and west into Thailand, Cambodia and southern Vietnam Tuesday and Wednesday; 75-150 mm (3-6 inches) with more isolated areas receiving 300 mm (12 inches) of rain will threaten these areas.
Due to the mountainous terrain of the region, rivers are expected to rapidly rise leading to life-threatening flash flooding. Water-logged hillsides may give way and lead to mudslides.

Drenching downpours and the threat for flooding could remain across Cambodia, Thailand and southern Myanmar during the second half of the week.
Despite containing locally damaging winds at the time of landfall, flooding rain is expected to be the primary concern and will threaten areas for several days.
Vamco originally took shape east of Vietnam early Sunday night, local time, and was classified as a tropical depression. The tropical cyclone quickly strengthened into a tropical storm before making landfall along the central coast of Vietnam.
