Weather forecast for May 28: Warning of heavy rain causing flash floods in Nghe An

According to the National Center for Hydro-Meteorological Forecasting, on May 28, the low pressure trough with an axis at about 20-23 degrees North latitude continued to be compressed by the continental high pressure in the North and pushed southward.

Due to the impact of the compressed low pressure trough combined with wind convergence up to 5,000m, there have been widespread thunderstorms in the North and Thanh Hoa. In the mountainous provinces of the North, there has been moderate to heavy rain, and in some places very heavy rain such as: Bac Quang (Ha Giang) 178mm, Bac Me (Ha Giang) 108mm, Trung Khanh (Cao Bang) 171mm.
