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.

The national flag carrier Vietnam Airlines has adjusted its flight schedules to ensure the safety of passengers and crew given the complicated developments of Typhoon Wipha, the third to hit the East Sea (South China Sea) this year.
