In addition, the National Center for Hydro-Meteorological Forecasting has just issued a warning that a large cloud area from the north of storm No. 3 is moving straight into the Hanoi area.

Based on satellite images, weather radar and lightning positioning systems, the meteorological agency said the rain-causing cloud area has begun to affect suburban districts of Hanoi, including Son Tay, Phuc Tho, Thach That, Hoa Lac and Co Loa.

This cloud area is forecast to continue to develop and expand, causing rain across the city. In the next 4 hours, the rain will spread to inner-city districts. Wards such as Viet Hung, Bo De (Long Bien), Hong Ha, Ba Dinh (Ba Dinh), Khuong Dinh (Thanh Xuan) and other central areas will have showers and thunderstorms.

Explaining why storm number 3 has light winds but heavy rains, the meteorological agency said the reason is because the main circulation cloud area of storm number 3 is concentrated in the west and south. Furthermore, as the storm moves further inland, its intensity has weakened significantly.

The main and most dangerous impact of storm No. 3 on Hanoi in the coming time will be heavy rain and extreme weather phenomena associated with thunderstorms such as tornadoes, lightning and strong gusts of wind, instead of widespread storm winds. People need to pay close attention to ensure safety.
