HANOI (Reuters) -Heavy rains triggered by tropical storm Wipha have caused severe flooding in the central Vietnamese province of Nghe An, killing at least three people and leaving one more missing.

Tropical storm Wipha weakened after making landfall in northern Vietnam on Tuesday, with authorities on alert due to heavy rains that could cause flooding and mudslides, as the Philippines struggled with monsoon downpours that began last week.
