According to the National Center for Hydro-Meteorological Forecasting, a weak cold air mass is moving southward over the Northern region. This system is expected to push down the low-pressure trough located between 24 degrees and 27 degrees North latitude starting April 3.
From the evening of April 3 to the early morning of April 4, most of the Northern region, excluding Dien Bien and Lai Chau, will likely experience showers and thunderstorms, with rainfall ranging from 10–20mm and locally exceeding 40mm.
During these thunderstorms, there is a possibility of strong winds, lightning, hail and tornadoes. Flash floods may occur along small rivers and streams, landslides may threaten slopes, and low-lying areas may experience flooding.
Residents in mountainous Northern regions are advised to monitor forecasts and take necessary precautions.
Meanwhile, in the Southeast region, temperatures recorded at meteorological stations on the afternoon of April 2 ranged from 33–35 degrees Celsius with humidity levels of 50–60 percent. Over the next 24–48 hours, the area is expected to continue experiencing heat, with maximum temperatures generally between 35–36 degrees Celsius and locally above 36 degrees Celsius, while minimum humidity levels drop to 45–50 percent.
From April 3 to 4, areas from Thanh Hoa to Quang Ngai are expected to see hot weather, with some locations experiencing severe heat. Maximum temperatures are forecasted at 35–37 degrees Celsius, locally exceeding 37 degrees Celsius, with minimum humidity between 40–45 percent. This heatwave in the Central and Southeastern regions is likely to persist for several days.
