From July 11 to July 23, Northern Vietnam is expected to endure two consecutive periods of heavy rainfall, prompting warnings about the heightened risk of landslides and flash floods. According to Nguyen Van Huong, Head of the National Center for Hydro-Meteorological Forecasting, the mountainous areas have already seen five days of continuous rain, saturating the ground and increasing the likelihood of dangerous natural disasters.

The forecast indicates that the region will continue to experience widespread moderate to heavy rain, particularly in the northern mountainous provinces and Quang Ninh. Over the past five days, rainfall has ranged from 70 to 150 mm, with some areas, such as Lai Chau, Dien Bien, Son La, and Lao Cai, recording between 100 to 200 mm. Notably, certain locations have reported exceptional rainfall exceeding 300 mm, including Hua Trai in Son La with 511.8 mm and Mong Cai in Quang Ninh with 469.6 mm.

Starting today, July 11, and continuing until July 18, Northern Vietnam will see persistent rain showers and thunderstorms across a wide area, with some regions expected to receive over 100 mm of rain. Furthermore, from July 19 to July 23, another significant rainfall event is anticipated, potentially influenced by a tropical convergence zone that may lead to the formation of tropical storms or depressions.

Given the ongoing heavy rain since June 7, the soil in the mountainous and midland regions is already saturated, reaching a critical state of saturation. Residents are urged to take proactive measures to prepare for the potential risks of flash floods and landslides, as the situation remains precarious in the coming days.
