Tropical Storm Dianmu killed one person and left four injured in northern Vietnam, local media reported Saturday.
The country's northernmost provinces were hit hardest as the storm made landfall on Friday at Haiphong, the country's third largest city, the Tuoi Tre newspaper reported.
Winds of up to 90 kilometres per hour and rainfall of 200 millimetres were reported.
One person was killed in Son La province near the Laotian border, with three other injured in Hanoi and one in Vinh Phuc province.
Although the storm weakened and dissipated late Friday, authorities anticipate flooding and mudslides in the northern mountains in the coming days.
