According to the National Center for Meteorological and Hydrological Forecasting, due to the influence of a low-pressure trough, on July 2nd, many areas in Northern Vietnam experienced showers, with localized heavy rain. Rainfall amounts up to 3 PM on the same day were recorded at Van Dinh (Hanoi) at 138.8mm, Vinh Tuong (Phu Tho) at 96.6mm, and My Lam (Tuyen Quang) at 73.2mm.

On the afternoon of July 2nd, the center of the tropical depression was located over the sea north of the Hoang Sa special administrative region, with wind speeds of level 7, gusting to level 9, moving in a west-northwest direction at a speed of approximately 25 km/hour.
Forecasts indicate that by the afternoon of July 3rd, the tropical depression is likely to strengthen into a typhoon as it moves towards the southeastern coast of Hainan Island ( China ). By July 4th, the typhoon will enter the northern part of the Gulf of Tonkin with an intensity of level 8, gusting to level 10, then continue to move in a north-northwest direction and gradually weaken into a tropical depression.
Due to the influence of the tropical depression's circulation, from the night of July 3rd to July 4th, the Northeast region and Thanh Hoa province are forecast to experience moderate to heavy rain and thunderstorms, with rainfall generally ranging from 30-70mm, and exceeding 120mm in some areas. From the night of July 4th to the end of July 5th, heavy rain will continue in the Northeast region with rainfall generally ranging from 70-130mm, and 120-180mm in the far Northeast, with localized areas exceeding 250mm.
In Southern Vietnam, including Ho Chi Minh City, thunderstorms will continue in the coming days, mainly occurring in the afternoon and evening. The highest temperature in Ho Chi Minh City will be 27-32 degrees Celsius, and the lowest 25-26 degrees Celsius. People should be wary of localized heavy rain, thunderstorms, tornadoes, lightning, and strong gusts of wind during the rain.
