In an offical document issued on September 3, the provincial Peopls's Committee directed all relevant departments and localities to closely monitor Yagi.
Relevant localities have notified owners of vehicles and captains of ships and boats operating at sea about the storm.
Districts and cities across the province were urged to keep ships operating in potentially affected sea areas informed of the storm's developments to avoid impacts and to prepare rescue plans if necessary.
Network operators and local mass media agencies need to ensure communication for response work, direct local agencies to increase sharing and guidance on the prevention of tropical depressions and storms, and give priority to broadcast warnings and response instructions.
