Hanoi and northern Vietnam face continued heavy rain

Hanoi rain northern Vietnam flooding drainage pumps weather forecast flash‑flood risk

A prolonged period of rain has affected Hanoi and the northern provinces of Vietnam since July 29, 2026. The downpour caused localized street flooding in Hanoi, but rapid response by the city's drainage authority, which operated pumps at full capacity, cleared water within hours and restored normal traffic flow.

Meteorological forecasts indicate that rain will persist through early August, with scattered showers and occasional heavy downpours. Temperatures are expected to range from 31 °C to 34 °C, accompanied by thunderstorms that may bring strong gusts, hail and lightning. Authorities warn of flash‑flood risks in low‑lying areas and advise residents to carry rain gear and avoid standing under large trees or fragile structures.
