Over the past three days, the northern mountainous and midland regions have experienced thunderstorms due to the convergence of southeast and southwest winds. The National Center for Hydro-Meteorological Forecasting stated that this pattern will continue, so tonight and on the night of 15/9, Lai Chau, Dien Bien, Lao Cai, and the northern part of Tuyen Quang (formerly Ha Giang) will continue to experience rain. The lowlands will see less rain, with sunny skies and high temperatures of 33-35 degrees Celsius, and some areas exceeding 35 degrees.

From the night of 16/9 to 20/9, the intertropical convergence zone and southeast winds will strengthen, leading to increased rainfall. Accuweather forecasts temperatures in Hanoi next week to range from 25-34 degrees Celsius, while Sa Pa (Lao Cai) will experience temperatures between 17-23 degrees.

The south-central coast, the Central Highlands, and southern Vietnam are currently influenced by the intertropical convergence zone around 9-12 degrees north latitude, resulting in thunderstorms. From 18/9 to 20/9, as the convergence zone strengthens, the areas from Quang Tri to Hue, the south-central coast, southern Vietnam, and the Central Highlands will experience heavier rainfall.

In the past month, northern Vietnam has recorded two heat waves, Thanh Hoa to Hue one heat wave, and the south-central coast has experienced a prolonged heat wave from 29/7 to the present. The national average temperature during this period is approximately the same as the long-term average; Nghe An to Da Nang is about 0.5 degrees lower.

The forecast for the coming month predicts temperatures nationwide to be generally around the long-term average, with northern Vietnam and Thanh Hoa to Ha Tinh 0.5-1 degrees Celsius higher.
