"Many streets were so deeply submerged that vehicles couldn’t move," the committee representative said. "The flash floods were caused by heavy torrential rainover the past few days."
Some other localities in the northern region including Hanoi, Quang Ninh, Dien Bien and Hai Phong have also reported serious floods since Sunday due to heavy rains.

Rain-induced inundation in the coastal city of Hai Phong also coincided with high tides, resulting in the most severe flooding since the beginning of the rainy season.
In the mountainous parts of Dien Bien and Quang Ninh provinces, warnings have been issued for flash floods and landslides.
Heavy flooding also resulted in traffic congestion and crop damage in these localities on Sunday.

The region might experience thunderstorms, tornadoes, lightning, hail and strong winds.
It also faces a risk of flash floods, landslides in mountainous areas and flooding in low-lying and urban areas.
