Nguyen Thi Lua, a local resident, reported that around 13:30, a small swirling column initially appeared, picking up objects from the ground. Within minutes, the waterspout rapidly grew, connecting to dark clouds above and forming a funnel-shaped column. Heavy rain then poured down on the area after the phenomenon ended.

A video recorded by Nguyen Thi Lua captured a gray-white swirling column extending from the ground to the base of the thunderstorm cloud. It moved within a narrow area across the field before gradually dissipating. Local authorities confirmed the waterspout caused no damage.

A waterspout is a strong swirling wind phenomenon that forms in a narrow area, creating a funnel-shaped air column connecting from a thunderstorm cloud to the ground. As it moves, a waterspout can pick up dust, water, and objects, causing the swirling column to appear white, gray, or black depending on the material drawn up.

This phenomenon often accompanies strong thunderstorm clouds, particularly cumulonimbus clouds. Though the affected area is not usually large, winds within a waterspout can be strong enough to rip off roofs, fell trees, and throw objects along its path.

According to the National Center for Hydro-Meteorological Forecasting (NCHMF), on 8/7, the northern mountainous and midland regions, along with Quang Ninh, continued to experience widespread rain of 20-40 mm, with localized amounts exceeding 100 mm. Other areas in the Northern region saw scattered showers and thunderstorms, with rainfall ranging from 10-30 mm, and some locations receiving over 70 mm, primarily in the afternoon and night.
