According to the National Centre for Hydro-Meteorological Forecasting, at 1:00 p.m. on September 18, the storm was located over the northeastern part of the East Sea, with maximum sustained winds of 62-74kph.

In the next 24 hours, Mitag is forecast to move toward the southern coast of China’s Guangdong province, and could gain further strength. By 1:00 p.m. on September 20, it is expected to make landfall in southern Guangdong and weaken into a tropical depression.

Though it does not directly hit Vietnam, Mitag’s circulation will bring heavy rain to northern and north-central provinces. Meteorologists forecast that these localities are anticipated to experience heavy rain, with rainfall ranging from 15–30 mm, or even exceeding 70 mm.

In the coming months, metrological experts said, the ENSO phenomenon is expected to remain in a neutral state from October to December 2025, leaning slightly toward La Niña conditions but not reaching full La Niña status.

The number of storms and tropical depressions in the East Sea affecting Vietnam may be higher than the long-term average. From October onward, cold air activity will increase in intensity and frequency, likely becoming stronger in November–December 2025. Severe cold spells in northern Vietnam could occur from late December, in line with the long-term average.
