In Hanoi, moderate to heavy rain and thunderstorms are expected from the night of December 12 through December 13. Temperatures will drop from December 13, with some areas likely to see a sharper decline.

At sea, northeasterly winds will intensify from midday December 13, generating rough seas and high waves across several maritime zones, posing risks to vessels and offshore operations.
