Sudden Thunderstorm Capsizes Tourist Boat In Ha Long Bay: Hydro-Meteorological Centre
The National Centre for Hydro-Meteorological Forecasting attributed the extreme weather to a convergence zone sweeping through the region, which, combined with three days of scorching temperatures, created unstable atmospheric conditions ripe for severe storms.
Meteorologists classified the event as a Mesoscale Convective System (MCS), a sprawling complex of thunderstorms that can span hundreds of km and persist for up to 24 hours. The system brought heavy downpours, lightning, strong gusts, and scattered whirlwinds to the region.

The provincial hydro-meteorological station had been tracking the developing weather system, issuing warnings based on real-time radar data. Specifically, upon detecting developing convective clouds, the station issued two warnings at 11:45 am and 1:30 pm on July 19. The second bulletin warned of showers and thunderstorms affecting areas including Ha Long ward, a popular tourist destination.
According to an urgent report from the provincial Steering Committee for Natural Disaster Prevention and Search and Rescue, a tourist boat, QN7105, carrying 48 passengers and five crew members, capsized around 3 pm on July 19 after being battered by a sudden whirlwind and thunderstorm. The incident occurred between Hon Ga Choi (Fighting Cock Islet) and Bai Tho mountain, roughly three nautical miles from shore.
A total of 47 people have been recovered, with ten survivors and 37 confirmed dead, including four victims whose identities are still being verified. The search continues amid challenging conditions.
The National Centre for Hydro-Meteorological Forecasting anticipated turbulent weather, with a marine bulletin issued at 4:30 am on July 19 forecasting scattered showers and thunderstorms across the Gulf of Tonkin by nightfall, along with the potential for whirlwinds and gusty winds. An extended-range forecast issued on July 18 afternoon had also warned of light rain during the day and thunderstorms at night along the Bai Chay coastal area, including Ha Long Bay, with the possibility of rough seas.
Looking ahead, the centre predicted continued showers and thunderstorms across the Gulf of Tonkin and northern and central of the East Sea, including the Hoang Sa (Paracel) archipelago, starting on July 20. The northern part of the northern East Sea is expected to face particularly severe conditions, with heavy rainfall and strong winds forecast.
