This year, the number of tropical storms and depressions are predicted to reach between seven and nine, including three to four directly affecting the Vietnamese mainland, largely the central and southern regions. 

For example, the second half of August and early September will see abnormal weather conditions hit the northern part of the East Sea, affecting both northern and north central provinces. 

Forecasters have warned that localities should take preventive measures aimed at easing the effects of strong storms which will likely feature complicated developments from September to December. 

In addition, localities have been advised to prepare for the risks of abnormal weather conditions such as thunderstorms, lighting, whirlwinds, and hailstones during the period.

With regard to temperatures and hot weather, the average nationwide temperature from September to November may be 0.5-1 degree Celsius higher than the average seen in previous years.
