As of July 8, 2026, many provinces in the midland and mountainous areas of Northern Vietnam are experiencing heavy rainfall, prompting warnings about the potential for flash floods and landslides in several districts.

The National Center for Hydro-Meteorological Forecasting has reported that from 1 PM to 3 PM on July 8, provinces such as Phu Tho and Lang Son experienced significant rainfall, with Mi Hoa station recording 61mm and Thach Kiet 1 station recording 49.4mm in Phu Tho, while Tam Gia in Lang Son saw 52mm.

Forecasts indicate that this evening and overnight, scattered rain and thunderstorms will continue in Northern Vietnam, with localized areas expected to receive very heavy rain. The soil moisture models suggest that some regions are nearing saturation, which raises concerns for further rainfall accumulation.

Warnings for Specific Areas

In the next 3 to 6 hours (from 3:30 PM), the affected provinces are expected to receive an additional 20 to 50mm of rain, with some areas possibly exceeding 80mm. There is a significant risk of flash floods in small rivers and streams, as well as landslides on steep slopes, particularly in the following districts:

Authorities are advising local agencies to review critical points and potential blockages to implement preventive measures and responses effectively.
